Single-beam light barriers make safety
modular
Low-cost single-beam light barriers offer options of infra-red or laser beams.
Pilz Automation Technology is launching low-cost single-beam light barriers with either an infra-red 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 EN954-1 Category 2, 3 or 4

Safety systems are put to the test
Pilz has developed a structured method for inspecting the safety-critical elements of plant and machinery to enable the suitability of the safety measures to be validated.
The sensors are quick and simple to install thanks to their compact M22 threaded bodies that are sealed to IP67, and wiring is completed via M12 connectors on the transmitter and receiver.
LEDs are incorporated within each unit to assist with commissioning and troubleshooting, and diagnostics are further improved by linking the sensors to either a Pilz PNOZmulti modular safety controller or a Pilz PSS (programmable safety system).
Indeed, it costs less to purchase three of the single-beam sensors and a PNOZmulti safety controller than to buy a standard three-beam safety light curtain for body detection.
The infra-red units have a maximum operating range of 8m and a response time of 2ms, whereas the laser version has an extended range of 40m and a response time of just 333us.
