SICK Background Suppression Photoelectric Sensor, Block Sensor

SICK Series W8 Photoelectric Sensor, 90% Reflectance Materials Detected, IP67 - WTB8-P2211

This photoelectric sensor detects objects using background suppression and is intended for industrial automation environments where reliable presence sensing is required. It operates using a visible red light source and is built as a Compact block-style unit with a plastic ABS enclosure and bracket mount for straightforward installation.

Features & Benefits

• PNP output permits easy integration with PLC inputs
  IP67 rating enables use in wet or dusty conditions
  Response time 500μs supports fast-moving target detection
  Operates between -25°C and 55°C for varied ambient conditions
  Accepts up to 30V DC and 100mA for common control circuits
  4-pin M8 connector allows simple plug-and-play wiring

**Applications**

• Suitable for conveyor line object detection with background suppression
  Ideal for pick-and-place verification of high-reflectance parts
  Used for end-of-arm sensing on robotic pick systems
  Can be used for presence detection in packaging machinery
  Suitable for machine guard monitoring where Compact sensors are required
