Rectangular plastic sensor housing 20 by 65 by 43 millimetres with M12 connector and reflector bracket

Sick

Sick WL250-P430 photoelectric retro-reflective sensor PNP electrician tool

SKU CH-VK82-03WAS

Photoelectric retro-reflective sensor detects objects up to 13.5 m with visible red LED, PNP output, M12 connector and IP67 housing

  • Detects objects up to 13.5 m with visible red LED
  • Adjustable sensing via 2-turn potentiometer for precise setup
  • Fast 1,000 Hz switching frequency suits high-speed lines
  • IP67-rated ABS housing withstands –25 °C to +55 °C operation
  • Includes P250 reflector and mounting bracket for immediate installation

Industrial sensing tool

The Sick WL250-P430 is a photoelectric retro-reflective sensor with PNP output designed for automation and electrical installation work. It operates on 10 V DC to 30 V DC supply voltage and detects objects at distances from 0.01 m up to 13.5 m using visible red LED light. The rectangular ABS housing measures 20 mm x 65 mm x 43 mm and carries an IP67 enclosure rating for harsh environments.

Suited for DC control circuits

This sensor suits engineers wiring 10 V DC to 30 V DC systems who need light/dark switching selectable via an L/D control cable and a 100 mA PNP output. It is not for applications requiring AC supply voltages or NPN switching logic. Buyers needing analog distance measurement or laser-class precision should look at other technologies.

Bracket and reflector included

The package supplies a P250 reflector and a BEF-W250 mounting bracket so the sensor can be aligned and fixed immediately. The potentiometer with two turns allows sensitivity adjustment on site without extra tools. A four-pin M12 male connector provides a standard industrial plug-in connection.

Questions about this item

What supply voltage must my system provide for the WL250-P430 sensor?

The sensor operates from 10 V DC to 30 V DC with a maximum ripple of 5 Vpp.

Will the PNP switching output work with my existing PLC input module?

Yes, the PNP output delivers up to 100 mA and is compatible with standard PLC inputs that accept a positive-switching signal.

How can I verify the sensor is detecting correctly after mounting?

With the reflector P250 in place, the LED indicator shows the switching state; the potentiometer allows fine adjustment and the 1,000 Hz switching frequency confirms reliable operation.
