SICK Through Beam Photoelectric Sensor, Rectangular Sensor

SICK W12 Series Photoelectric Sensor, IP66/IP67/IP69K, 30V DC Maximum DC Voltage - WSE12-3P2431

This photoelectric sensor detects objects using a through‑beam optical arrangement and is intended for industrial automation environments. Housed in metal with a rectangular form, it connects via an M12 4‑pin Interface and is designed for applications where robust ingress protection and Compact mounting are required.

Features and Benefits:

• IP66 IP67 IP69K ingress protection for harsh environments
  PNP output enabling straightforward positive‑switching integration
  30VDC maximum supply for standard control systems
  100mA maximum current supporting common load devices
  −40 to 60°C operating range for varied temperature conditions
  330μs response time for Rapid detection in fast processes

Applications

• Suitable for conveyor object detection in food processing lines
  Ideal for machine safety beam monitoring where wash‑down is required
  Used with PLCs in assembly automation requiring quick switching
  Can be used for presence sensing on robot‑tended workstations
  Used for gap or edge detection in packaging machinery

What connector type is provided for wiring?

A 4‑pin M12 connector is fitted to the sensor for industrial cabling and straightforward interfacing.

Which mounting methods suit constrained machine spaces?

The unit supports threaded and hole mounting allowing fixed installation in confined assemblies.

What approvals and standards relate to electromagnetic or safety aspects?

It complies with EN IEC 63000 and carries UL file references for recognised assessment.

What light source does it use and what does that mean for visibility?

An LED emitter provides a stable, low‑power optical beam suitable for reliable through‑beam sensing.
