Light Barriers use single infrared or laser beam.March 21, 2008 -
Suited for machinery safety applications, PSEN op2S/4S Light Barriers feature M22 threaded bodies that are sealed to IP67. Wiring is completed via M12 connectors on transmitter and receiver. Infrared units have max operating range of 8 m and response time of 1.5 ms, while laser version has extended range of 40 m and response time of 320 µs. Barriers conform to requirements of BS EN 954-1, Category 2, 3, or 4, and are compliant and approved in accordance with EN61496-1 and IEC61496-2.

Pilz Automation Safety Introduces Low-Cost, Single-Beam Light Barriers
(CANTON, MI) - Pilz Automation Safety LLC is launching new low-cost, single-beam light barriers with either an infrared beam or - for applications where extremely rapid response or a long sensing range is required - a laser beam. Considerably more cost-effective than safety light curtains for body detection, the PSEN op2S/4S light barriers are suitable for use in machinery safety applications conforming to the requirements of BS EN 954-1, Category 2, 3 or 4, and compliant and approved in accordance with EN61496-1 and IEC61496-2.
"The sensors are quick and simple to install thanks to their compact M22 threaded bodies that are sealed to IP67," says Pilz Engineer Mike Poynter. "Wiring is completed via M12 connectors on the transmitter and receiver."
Light-emitting diodes (LEDs) are incorporated within each unit to assist with commissioning and troubleshooting. Diagnostics are further improved by linking the sensors to either a Pilz PNOZmulti modular safety controller or a Pilz Programmable Safety System (PSS).
"It costs less to purchases three of the single-beam sensors and a PNOZmulti safety controller than to buy a standard three-beam safety light curtain for body detection," Poynter points out.
The infrared units have a maximum operating range of 8 meters and a response time of 1.5 ms, while the laser version has an extended range of 40 meters and a response time of just 320 microseconds.
The PSEN op2S/4S is part of Pilz's expansion of its PSENopt family of safety light curtains, making it one of the most comprehensive product lines in the industry. The Pilz PSENopt family now meets virtually every requirement: Type 2 and Type 4 light curtains for finger, hand or body detection; cost-effective single-beam light barriers; light curtains with muting and fixed/floating blanking; cascading light curtains; and light curtains for use with SafetyBUS p.
"When you factor in 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 be the first call customers make when considering installing safety light curtains on new machinery or older machines for reasons of safety or productivity," Poynter says.
