Low-cost light barriers have fast laser
option
Low-cost single-beam light barriers are provided with either an infrared beam or, for applications where extremely rapid response or a long sensing range is required, a laser beam.
Pilz Automation Technology 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

Pilz relays measure electricity/temperature
Pilz's PMDsigma range of electronic monitoring relays measure voltage, current, temperature, phase sequence, true power and similar variables.
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 infrared units have a maximum operating range of 8m and a response time of 2ms, while the laser version has an extended range of 40m and a response time of just 333 microsec.
