SICK Retroreflective Photoelectric Sensor, Rectangular Sensor

SICK W150 Series Photoelectric Sensor, IP67, 0.5ms Response Time - WL150-P430

This photoelectric sensor is a Compact retro-reflective detection device designed for industrial automation tasks. It uses visible red LED illumination and a dual-lens receiver to detect objects against a reflector, delivering Rapid switching for control and monitoring in production and handling systems. The unit connects via an M8 4-pin male connector and is supplied with a mounting bracket and reflector for quick installation.

Features & Benefits

• Response time 0.5ms for fast object detection
  Switching frequency 1000Hz to handle high-speed cycles
  PNP output with less than or equal to 100mA maximum current for direct interfacing
  Operates from 10V DC to 30V DC for common control voltages
  IP67 enclosure rating for use in harsh environments
  Polarisation filter reduces false triggers from stray light

**Applications**

• Suitable for conveyor detection where reflective sensing is required
  Ideal for part presence checks in pick-and-place systems
  Used with small reflectors for position verification in Compact machines
  Can be used for edge detection on packaging lines
  Used for automation set-ups requiring panel mounting and connectorised wiring

What connector and wiring format are used for installation?

It employs a male M8 4‑pin connector configured for standard sensor/actuator cabling with L+/L− and output lines.

How is sensing range adjusted for different reflectors?

A multi-turn potentiometer provides fine sensing-range adjustment to match reflector types and working distances.

What indicators assist with setup and diagnostics?

Two LEDs show stability and output status, aiding alignment and signal verification during commissioning.

What materials make up the housing and optical components?

The body is moulded plastic and the optical elements are MADE from PMMA to balance durability and clarity.
