SICK Through Beam Photoelectric Sensor, Rectangular Sensor

SICK Series W8 Photoelectric Sensor, IP67, 30V DC Maximum Voltage - WSE8-P2131

This photoelectric sensor is a through-beam detector designed for machine Vision and automation tasks where rapid, reliable object recognition is needed. It employs an LED light source within a robust plastic enclosure to detect objects travelling at high speeds. The device is intended for industrial environments and is built to withstand exposure to dust and water while operating across a broad temperature range.

Features and Benefits:

• Response time 0.25 MS enables detection of very fast-moving objects
  Output type PNP allows straightforward sourcing signal integration
  IP67 rating protects electronics from dust ingress and temporary immersion
  Maximum supply 30V DC supports common industrial control voltages
  Maximum current 100 mA limits load selection for safe switching
  Terminal 3-pin configuration simplifies wiring and mounting

Applications

• Suitable for high-speed conveyor object counting in packaging lines
  Ideal for stacker/crane presence detection in material handling
  Used for cycle timing in automated assembly processes
  Can be used for access detection on robotic end-of-arm tooling

What environmental temperatures can it tolerate during continuous operation?

It operates continuously between -25°C and 55°C without specified derating for response performance.

Which mounting styles are supported for stable installation?

The unit is compatible with threaded and through-hole mounting to accommodate fixed-panel or bracket installations.

How is the sensor sealed against contaminants on busy factory floors?

The enclosure conforms to an IP67 ingress rating, preventing particulate entry and resisting temporary immersion.

What signalling behaviour should be expected when integrating with control systems?

The device provides a PNP switching output suitable for sourcing positive voltage to a PLC input or relay coil.
