SICK Background Suppression Photoelectric Sensor, Rectangular Sensor

SICK Series W4 Photoelectric Sensor, Laser Light Source, IP67/IP66 - WTB4SL-3P2261

This photoelectric sensor is a Compact background suppression device intended for industrial detection of small objects using a laser light source. It operates in demanding automation environments with a rectangular plastic housing designed for threaded mounting and offers standard electrical interfacing for integration into control systems.

Features and Benefits:

• Background suppression detects targets against variable backgrounds
  Laser illumination supports precise small object sensing
  PNP switching enables simple sourcing output connections
  500μs response time permits high-speed production checks
  Rated for 30VDC operation for common control voltages
  IP66 and IP67 ingress protection for dusty and wet conditions

Applications

• Suitable for part presence checks on high-speed conveyors
  Ideal for pick-and-place verification in assembly stations
  Used for label detection where reflective backgrounds vary
  Can be used for edge detection in machine guarding systems

What electrical connection does it use for wiring?

It employs a four-pin Terminal Interface for power and signal cabling.

Which temperature range supports uninterrupted operation?

It functions reliably between -10°C and 50°C for typical factory ambient conditions.

What materials can it reliably sense?

It is configured to detect small objects regardless of common substrate composition.

How does the enclosure fare against industrial contaminants?

The polymer housing combined with its ingress ratings provides resistance to dust ingress and water jets.
