Safety light curtains to suit virtually every application
Pilz is expanding its PSENopt family of safety light curtains, making it one of the most comprehensive ranges on the market. Taking into account the competitive prices and the fact that the company has the application expertise to advise customers on how best to use safety light curtains, Pilz should now be the 'first port of call' for customers considering installing safety light curtains on new machinery or older machines for reasons of safety or productivity.
A new addition to the PSENopt range is a series of light curtains that can be used in L or T arrangements for muting in one or two directions, and customers can select the number of muting sensors. Fixed and floating blanking can also be used with a number of the new models of light curtain.
Another exciting development is cascaded light curtains that can be used in a master-and-slave configuration. This ensures full monitoring within the protected zone, with the light curtains mounted in such a way as to suit the machine's layout. Compared with using multiple conventional light curtains, cascaded light curtains can be far more economical.
For small, localised plants, Pilz now offers cost-effective feedback loop monitoring in which contact expander modules or contactors are connected directly to the OSSD (output signal switching device) outputs. Switch status is monitored via the feedback loop function.
The Pilz PSENopt range now meets virtually every requirement: Type 2 and Type 4 light curtains for finger, hand or body detection; cost-effective single-beam light barriers (and laser versions for ultra-fast response and distances of up to 40m); light curtains with muting and fixed/floating blanking; cascading light curtains; and light curtains for use with SafetyBUS p.
To complement these products, there is also an extensive range of accessories, plus Pilz can supply whatever monitoring devices are appropriate, including safety relays, PNOZmulti configurable safety controllers, and PSS programmable safety systems (safety PLCs). If required, Pilz also offers application support and advice on product selection, as well as ESPE (electrosensitive protective equipment) inspections to ensure that light curtains cannot be defeated and that they are correctly positioned in relation to the mechanical hazards - for reasons of both safety and productivity.
