Sick WT34-R210 photoelectric proximity sensor

Sick WT34-R210 photoelectric sensor

The Sick WT34-R210 is a rectangular photoelectric proximity sensor that uses background suppression to detect objects reliably. It emits infrared light from an LED source and provides a sensing range from 100 mm up to 2,500 mm. The housing measures 27 mm by 92 mm by 70 mm and weighs 140 g. It is rated IP67 and operates from –40 °C to +60 °C.

Industrial automation and material handling

This sensor suits production lines, conveyors and packaging machines that need adjustable detection distances and a relay output with change-over contacts. The wide supply voltage of 20 V to 250 V AC/DC fits many control cabinets without extra transformers. Buyers who need faster switching than 10 Hz or a solid-state output instead of a relay should look at something else.

2,500 mm range with potentiometer adjustment

The potentiometer lets installers set the exact switching point anywhere within the 100 mm to 2,500 mm window, giving comfortable headroom for varying target positions. At the maximum distance the light spot grows to roughly 80 mm, so very small objects at long range may not be detected reliably. The relay handles up to 4 A at 250 V AC or 24 V DC with a 10 ms response time.
