SICK Background Suppression Photoelectric Sensor, Rectangular Sensor

SICK W8 Laser Series Photoelectric Sensor, Background Suppression Detection Type, IP67 - WTB8L-P2131

This photoelectric sensor is a laser-based detector designed to identify small and fast-moving objects in industrial automation environments. It operates using background suppression to distinguish targets from their surroundings and is suited to installations requiring a robust, Compact rectangular sensor with sealed protection for harsh conditions.

Features and Benefits:

• Laser light source enables precise small-object detection
  Background suppression provides consistent target discrimination
  Response time 250μs supports high-speed detection tasks
  PNP output allows straightforward integration with control systems
  IP67 rating ensures resistance to dust and water ingress
  Maximum 30V DC and 100mA operation matches common control voltages

Applications

• Suitable for feed monitoring on high-speed conveyors
  Ideal for pick-and-place verification of miniature components
  Used for presence sensing in automated assembly lines
  Can be used for reject logic in packaging inspection systems
  Suitable for object counting where background contrast varies

What connector type is used for electrical connection?

The unit employs an 8-pin connector Interface to link with external controllers and signal wiring.

How is the sensor mounted in machinery?

It is supplied for hole and threaded mounting to secure the rectangular body to machine frames.

What temperature range can it operate within?

It functions reliably from −10°C up to 50°C for typical industrial ambient conditions.

What approvals certify its suitability for industrial use?

It carries CE and UL certifications indicating compliance with recognised safety and performance standards.
