SICK Background Suppression Photoelectric Sensor, Block Sensor

SICK Series W2 Photoelectric Sensor, Background Suppression Detection Type, IP67 - WTB2S-2P3251

This photoelectric sensor is a background suppression device designed for industrial detection tasks using an LED light source. Built in a robust ABS housing with an IP67 rating, it is intended for panel mounting in automation and machinery environments where reliable detection of non-metallic materials is required.

Features & Benefits

• Background suppression enables accurate object separation during operation
  PNP output provides straightforward integration with control systems
  500μs response time supports Rapid object detection in high-speed processes
  Operates between -25°C and 50°C for varied environmental conditions
  M8 connector allows compact, secure electrical connection
  Maximum supply 30V and current 20mA minimise power draw

**Applications**

• Suitable for detecting plastic components on conveyors
  Ideal for quality control of polymethyl methacrylate parts
  Used with automated panel-mounted inspection stations
  Can be used for proximity switching in assembly lines
  Suitable for integration into industrial LED sensing networks
