SICK Background Suppression Photoelectric Sensor, Block Sensor

SICK Series W2 Photoelectric Sensor, Background Suppression Detection Type, IP67 - WTB2S-2P1330

This photoelectric sensor is a Compact optical detector designed for presence sensing and background suppression in industrial control systems. Housed in a robust ABS enclosure, it is intended for panel mounting and provides a reliable LED light source for Rapid detection in automation, electronics and mechanical workflows. The device connects via an integrated wire cable and delivers a PNP switched output compatible with low-voltage DC control circuits.

Features & Benefits

• Background suppression delivers precise object discrimination under cluttered conditions
  Ingress protection to IP67 enables use in wet or dusty environments
  PNP output supports direct interfacing with common control inputs up to 30V
  0.4ms response time allows high-speed detection in Rapid production lines
  Low operating current of 20mA minimises load on supply and drivers
  Wide ambient range from -25 to 50°C preserves operation across shifts

**Applications**

• Suitable for conveyor object detection where background suppression is required
  Ideal for pick-and-place machines requiring fast optical switching
  Used with PLCs and controllers that accept PNP sensor inputs
  Can be used for panel-mounted monitoring in manufacturing enclosures
  Suitable for inspection stations operating in challenging ambient conditions

How is the sensor connected to a control system?

It is supplied with a fixed wire cable terminating in conductors for power and the PNP switched output, allowing direct wiring to DC control inputs.

What materials ensure suitability for industrial panels?

The enclosure is MADE from ABS plastic, offering mechanical stability and electrical isolation for mounted installations.

How does the sensor cope with harsh environmental exposure?

The unit meets an IP67 rating, providing dust-tight protection and immersion resistance for temporary exposure to water.

What electrical limits must be observed when wiring?

The switching output must not exceed 30V DC and the device draws a maximum of 20mA during normal operation.
