Photoelectric guards meet IP69K standard

The latest photoelectric guards in the demanding IP69K standard are able to withstand high pressure cleaning and available with protected heights from 330mm to 1130mm.

Balluff's latest safety brochure is now available. Featured within the new full colour brochure are Safety Control's latest photoelectric guards including the Type 4 guard now available in the demanding IP69K standard. This IP69K photoelectric guard is able to withstand high pressure cleaning and are available with protected heights from 330mm to 1130mm to 30mm resolution.

Safety Control also claims the world's smallest Type 4 Guard - the Linesmart with 14mm and 30mm resolution - has an ultra slim body at just a 12mm x 20mm cross section for the 30mm version.

The ALFA 2 and ALFA 4 range provide for all the required options of blanking - fixed and floating - muting, cascade, PC diagnostics and function setting.

One piece, compact robust housing give the utmost protection to the optics coupled with an increased resistance to impact.

This increased impact resistance of these guards helps to ensure a long service life, resulting in value for money and loss of down-time.

Safety light curtains have tough housings

A series of safety light curtains produce safety protection in those tough arduous environments and have strong torsionally stiff housing or high immunity from EMC disturbance.

The new Solid-4E safety light curtain, being introduced by Leuze Mayser, is ideally suited for creating safety protection in those tough arduous conditions environments. Accidental collision is catered for by its strong torsionally stiff housing or high immunity from EMC disturbance, thus assuring reliable protection against intrusion into hazardous areas all times. Trouble-free performance is complimented by a choice of four standard resolutions - 20, 30, 40, 90mm - making Solid 4E an extremely flexible safety light curtain, for hazardous point protection or area protection across many diverse applications.

These can include finger and hand protection at presses and stamping machines for the metal, leather and plastics industries or at manual inserting areas of automated manufacturing cells.

Where multiple light curtain guarding requirements are needed in close proximity the Solid 4E is in a field of its own since it incorporates two different and adjustable light-beam codings.

This eliminates potential optical cross-talking of neighbouring devices ensuring completely reliable safety protection.

Besides integrated standard functions such as restart interlock and relay monitoring, the Leuze Mayser intelligent interface devices of the MSI series are available as a flexible function extension like muting, single/double break or the connection of safety switches.

Another big plus factor for Leuze Mayser's new Solid 4E safety light curtain is maintenance-free operations due to the fail-safe OSSD transistor output.

Various LEDs and a digital display indicate the OSSD status, report weak reception signal and help make adjustments or quickly perform error diagnostics on site.

In developing Solid 4E, Leuze has brought inner strength to the world of safety light curtains, creating a product range that will give lower cost of ownership in terms of performance, easier installation and trouble-free operation.

Fortress' eGard, a product which combines machine safety and control modules in one flexible unit, has gained the prestigious 'Green' Innovation Award

Fortress' eGard, a product which combines machine safety and control modules in one flexible unit, has gained the prestigious 'Green' Innovation Award.


Fortress Interlocks has won the prestigious 'Green' Innovation Award at this year's innovation and Design Excellence Awards (iDEA) against strong competition. The award, announced at a gala reception at the Hilton Hotel in London at the end of September, was for Fortress' eGard, a unique new product which combines both machine safety and control modules in one flexible unit. The iDEAs, organised by Eureka, New Electronics and Cranfield School of Management, recognised that the innovation behind eGard opens up a new, large market sector for Fortress.

The award also recognised that Fortress designed and manufactured eGard along environmental principles following advice from Envirowise, taking into account the whole life-cycle of the product.

eGard has a radical design and is a completely new approach to controlling access to hazardous machinery and equipment.

It is built from clip-together modules and integrates trapped key and safety gate technology with service modules such as indicators and buttons, internal releases and emergency stops.

The internal network is self-configuring.

Fortress decided to make the housing from polymer and the main advice from the environmental Envirowise 'audit' was to use the same material throughout to make recycling more efficient.

Fortress elected to use a glass-filled grade of PBT.

Other parts are made of stainless steel.

In addition, the housing has no fixings or adhesive; parts are clipped together or ultrasonically welded.

This reduces component count and also makes recycling much easier.

* Note that Envirowise is a government-supported environmental consultation service which offers UK businesses free, independent advice on ways to increase competitiveness by using resources efficiently, minimising waste, and reducing environmental impact.

Single-axis probes for selective radiation meter

New from Link Microtek are three new single-axis probes for the Narda SRM-3000 selective radiation meter, for measuring emissions from each source within a multiple-frequency RF environment.

New from RF radiation safety specialist Link Microtek are three new single-axis probes for the Narda SRM-3000 selective radiation meter - an innovative instrument that is capable of measuring emissions from each individual source within a multiple-frequency RF environment. The new probes extend the capabilities of the SRM-3000 to frequencies as low as 100kHz and enable it to measure emissions at radio transmitter sites or in factories using equipment such as RF heat sealers or industrial dryers. With the European EMF Directive due to come into effect in April 2008, employers will be responsible for ensuring that RF emissions do not exceed the maximum permissible limits laid down by the International Commission on Non-Ionising Radiation Protection (ICNIRP).

In multiple-signal environments where the field strength is above the ICNIRP limit of 10W/m2, employers may find that they can still prove compliance by using the SRM-3000 with the new single-axis probes to check the contributions from individual signals, thereby avoiding the disruption and cost of unnecessary remedial action.

Two of the three new probes - an active dipole E-field antenna and an active H-field antenna - cover the frequency range 100kHz to 300MHz and are designed for near-field measurements, which require E and H components to be checked separately.

The third single-axis probe is a passive dipole E-field antenna for use over the frequency band 27MHz to 3GHz.

Lone worker solutions demo online

SBES, the lone worker protection specialist has virtual demonstrations of some of its products in action, these are available to view online.

To help those researching lone worker solutions find the right products for their particular application SBES, the lone worker protection specialist has virtual demonstrations of some of its products in action, these are available to view online. The virtual demos demonstrate the flexibility of the SBES product portfolio and will help those who have identified a problem with lone working as part of a risk assessment decide on which product is best suited to their environment or application. Beginning with a demonstration of SBES' core product, Lifesaver, the demos give a short but clear indication of what each product in the range covers and what it can be used for.

The Lifesaver demo for example shows a warehouse application and clearly shows how SBES deals with problems associated with signal coverage and the reaction time of the system.

For mobile workers, the Protector virtual demo is a clear run through of how the system might be used by maintenance/ service personnel frequently moving between buildings.

Tracer, the GPS/GSM and two-way satellite enabled vehicle-based system is demonstrated by showing the classic case of a lone operative, working at height in a remote location who has an accident.

This demonstration clearly shows how the remote monitoring centre, which such systems can be relayed to, answers the call with speed and accuracy.

Using GSM/GPS or two-way satellite communication to suit the particular application the Tracer system can pinpoint a prone operative to within 1m whatever their location - anywhere in the World.

SBES' latest technical innovation is shown in the last virtual demonstration where the backpack mounted Responder system is shown in various situations.

The Responder system again uses GSM/GPS or two-way satellite communication and is equally suited to lone workers undertaking potentially hazardous tasks in the field or service workers walking between locations in a City centre.

Leisure is also covered by the Responder system and activities such as walking, running, mountain biking, climbing, hiking and sailing are all areas in which participants could be effectively protected.

As SBES CEO Peter Swan says 'We know that our lone worker solutions are suitable for use in a wide range of applications.

The virtual demonstrations, while only covering a few applications, illustrate the modular nature of all of our solutions.

We hope that this facility will help those who have identified a potential risk be assured that there is a proven, cost effective solution available.

But, if people have any doubts they should not hesitate to contact SBES' specialist staff who will be pleased to help.'

Emergency Stop buttons have embedded LEDs

Emergency Stop pushbutton stations have the face of the pushbutton illuminated - when the emergency stop station is in normal status the LED's illuminate green, or red if activated.
Jokab Safety have launched a new range of emergency stop pushbutton stations. The SMILE range has six different models which allow the user to connect to either conventional safety relays or Jokab Safety's cost saving Vital system. There are two models with cable connection, two models with one M12 connector and the final two models have two M12 connectors for 'daisy chain' connections.
The enclosure has been reduced to save on space when installing the stations and they are excellent for mounting on aluminium and steel guard fencing.
The main unique feature is the face of the pushbutton is can be illuminated.
When the emergency stop station is in normal status the LEDs will illuminate green, if the e-stop is activated the LEDs will change to red on the station that has been activated.
This means that it is easy to identify which station has been activated.
The E-stop stations can be connected in various ways in order to meet the user's safety requirements.

Miniature photoelectric switches get suppression

IDEC Electronics has introduced background suppression types as an addition to its SA1E range of miniature photoelectric switches.
IDEC Electronics has introduced background suppression types as an addition to its SA1E range of miniature photoelectric switches. The aim of the SA1E range is provide a really low cost alternative in the main application areas for photoelectric switches. Prices start from just GBP31! Measuring only 36mm by 19mm by 11mm, the SA1E switch provides through beam, retro-reflected (uses a reflector plate) and diffuse/spot reflected options (reflects from the object).
Up to 700mm range can be achieved for the diffuse switch and up to 10 metres is possible for the through beam transmitter/receiver pair.
There are two connection methods offered, either by a built-in cable or M8 connector.
Matching M8 cables are available of different lengths.
The background suppression types (range 20 to 200mm) allow the range to be set to only detect the objects passing in front of the lens at the specified distance Objects of different colours will present no problem, also the background because it is beyond the set range will not cause the switch to operate.
This remarkable little switch has a supply range of 12 to 24vdc, a switching speed of 1ms and with an IP rating of IP67 can be expected to operate in the harshest environments.

Sightglasses to safely enable thermography scans

A multiple unit nuclear generating station has adopted the C-Range Hawk IR Sightglasses to safely enable IR thermography scans of Medium Voltage (MV) motor junction boxes.
A multiple unit nuclear generating station has adopted the C-Range Hawk IR Sightglasses to safely enable IR thermography scans of Medium Voltage (MV) motor junction boxes. MV Motors, in particular the junction boxes, are the keystone for a nuclear generating station, providing a junction between large field cabling and the rotating machinery used to power coolant pumps and other critical drives. The Electrical Safety Standard, NFPA70E, has driven the increase in safety awareness, especially in the electrical IR thermography community.
Due to arc-flash hazards, it is not practically and/or safe to remove large, heavy motor box covers to all IR Inspection.
Two IR Windows were installed into each MV Motor Junction box allowing an IR thermographer to inspect both field and motor side cable connections at the motor during running.
Arc-Resistant C-Range IR windows using the revolutionary CLIRVU optic material can protect an infrared thermography should an arc-flash occur In addition to standard electrical requirements, the nuclear industry must also consider the effects of seismic activity on the installation.
The revolutionary fixing method used by Hawk IR ensures that dielectric clearances are not reduced - a MUST when retrofitting - but has also passed the stringent requirements of the nuclear industries seismic standards.
The installation of Infrared Windows, the nuclear industry is leading the field in electrical safety and reliability.
