SICK Through Beam Photoelectric Sensor, Rectangular Sensor

SICK W250-2 Series Photoelectric Sensor, IP67, 30V DC Maximum Voltage - WSE250-2P2431

This photoelectric sensor detects objects using a through-beam LED arrangement and is designed for industrial automation environments. It is housed in a robust plastic enclosure with a rectangular profile and connects via an M12 four‑pin interface, making it suitable for integration into control systems where discrete object detection and reliable signal transmission are required.

Features and Benefits:

• PNP output provides easy integration with PLC inputs
  Response time 500 μs supports high‑speed detection
  IP67 protection allows wash‑down and dusty environments
  Operates from 30V DC for standard control voltages
  Rated for −25 to 55 °C operation for variable ambient conditions

Applications

• Suitable for conveyor part detection in automated lines
  Ideal for presence sensing in packaging machines
  Used with pick‑and‑place equipment for object validation
  Can be used for entry/exit counting in material handling
  Suitable for alignment checks in assembly stations
