SICK Background Suppression Photoelectric Sensor, Block Sensor

SICK Series W2 Photoelectric Sensor, IP67, 0.4ms Response Time - WTB2S-2P3130

This photoelectric sensor detects objects using a focused LED emitter and is intended for industrial sensing tasks where background suppression is required. It is a panel-mounted block-style device designed to operate across typical factory temperature ranges and connects via a three-pin M8 Terminal for straightforward integration into control systems.

Features & Benefits

• 0.4 MS response time enables high-speed detection
  PNP output simplifies sourcing-type interfacing
  IP67 rating allows washdown and dustproof installation
  Plastic ABS housing reduces weight and resists impact
  Operates from -25°C to 50°C for broad ambient use
  Maximum 30V DC and 20 mA draw minimise power requirements

**Applications**

• Suitable for presence detection on conveyor lines
  Ideal for distinguishing parts against varied backgrounds
  Used with automated pick-and-place equipment
  Can be used for end-of-line inspection stations
  Suitable for panel-mounted machine control cabinets

What electrical connection does it require?

It uses a three-pin M8 Terminal for signal and supply wiring, compatible with common industrial cabling.

How does the sensor behave where liquids or dust are present?

With its IP67 ingress protection it maintains operation when exposed to dust and temporary immersion conditions, making it appropriate for harsh environments.

What are the maximum supply limits to observe?

The device must not exceed 30V DC and draws up to 20 mA during operation to avoid electrical stress.

Which mechanical mounting approach is used?

The unit is designed for panel mounting in a Block format to allow secure installation within control panels or machine frames.
