Industrial photoelectric sensor for automation

The Sick WT34-R250 is a rectangular photoelectric proximity sensor that uses visible red LED light with background suppression to detect objects at distances from 100 mm to 1,200 mm. It is built for electricians and automation engineers who need reliable presence detection on conveyors, packaging lines or machine guarding applications where ambient light varies.

ABS housing with IP67 rating and gland entry

The sensor measures 27 mm by 92 mm by 70 mm and weighs 140 g, enclosed in ABS plastic rated IP67 for dust and water protection. A terminal connection with an M16 cable gland provides secure wiring for the 20 V to 250 V AC/DC supply, while the potentiometer and selector switches allow on-site adjustment of sensing range, light or dark switching and an off-delay of 0.5 s or 10 s.

Relay output switching at 10 Hz with low consumption

An electrically isolated change-over relay handles up to 4 A at 250 V AC or 24 V DC, consuming less than 2 VA. Response time is 10 ms at a 10 Hz switching frequency, suitable for medium-speed counting or sorting tasks. The unit operates from –40 °C to +60 °C and meets usage categories AC-15 and DC-13 per EN 60947-1, with protection classes A and C built in.
