Sick WTB8-P2131 Фотоэлектрический датчик

SICK Series W8 Photoelectric Sensor, Background Suppression Detection Type, IP67 - WTB8-P2131

This photoelectric sensor detects objects using background suppression and is designed for panel mounting in industrial control environments. It uses an LED light source and a block-style housing MADE from ABS plastic to perform proximity sensing where separation from background signals is required. The device operates within typical industrial temperature ranges and connects via a 3-pin M8 Terminal for straightforward integration into automation systems.

Features & Benefits

• PNP output provides direct sourcing for control inputs
  IP67 protection allows use in wet or dusty environments
  0.5ms response time supports high-speed detection tasks
  30V maximum DC rating suits common 24V control systems
  Short-circuit proof design enhances electrical fault tolerance
  Operational range from -25 to 55°C enables wide ambient use

**Applications**

• Suitable for conveyor part presence detection in assembly lines
  Ideal for pick-and-place verification in automated cells
  Used for object counting where background suppression reduces false triggers
  Can be used for end-of-travel sensing on pneumatic actuators
  Suitable for integration with PLC inputs requiring PNP sensors

What connector type does it use for wiring?

It employs a 3-pin M8 connector for compact, standardised cabling and quick replacement.

How does the enclosure perform against contaminants?

The housing meets IP67 criteria, allowing immersion and protection against dust ingress for reliable operation in harsh areas.

What standards cover its photobiological safety?

It conforms to DIN EN 62471 requirements for photobiological safety of lamps and light sources.

Can it be used where regulatory approvals are required?

It carries EU, UK and ACMA approvals, and complies with RoHS restrictions for restricted substances.

Notes

For retro-reflective sensors a suitable reflector is required.
For PL80A, PL30A & C110 reflectors see stock nos. 265-2776, 265-2760 & 265-2748 respectively.
