SICK Retroreflective Photoelectric Sensor, Block Sensor, 4 m, PNP, IP67

SICK Series W8 Photoelectric Sensor, IP67, PNP Output Type - WL8-P2131

This photoelectric sensor is a Compact retro-reflective detection device designed for industrial automation tasks. It employs an LED light source to sense objects moving at high speeds and is housed in a rectangular plastic enclosure with a bracket mount for installation in factory and machinery environments.

Features and Benefits:

• PNP output delivers easy integration with common control systems
  250μs response time enables Rapid detection of fast-moving items
  IP67 protection allows use in dust-prone and washdown zones
  30VDC maximum supply lets it operate from typical industrial supplies
  100mA maximum current supports low-power switching loads
  3-pin Terminal simplifies wiring and connection checks

Applications

• Suitable for high-speed conveyor object presence monitoring
  Ideal for pick-and-place machine part detection
  Used for label or package alignment in packing lines
  Can be used for end-of-travel sensing on automated feeders

What ambient temperatures can it withstand in operation?

It operates reliably between -25°C and 55°C, covering common cold-room staging to warm plant-floor locations.

How is the device mounted and oriented on machinery?

It is secured using a bracket mount that supports fixed alignment with a retro-reflective target or reflector.

Which materials does the sensor detect most effectively?

The LED-based retro-reflective arrangement is optimised for detecting moving objects, including varying surface finishes when used with an appropriate reflector.

What approvals or standards does the unit conform to?

It meets applicable EN IEC 63000 standards and related RL and EU approvals, indicating adherence to specified regulatory requirements.
