SICK Optical Photoelectric Sensor, Fork Sensor

SICK Series WF Photoelectric Sensor, IP65, 0.1ms Response Time - WF15-40B410

This photoelectric sensor is an optical device designed for object detection in industrial automation and control systems. It operates using an infrared light source in a fork-style arrangement to detect interruptions or presence of targets, and is built for panel mounting in production and testing environments.

Features & Benefits

• Aluminium housing rated to IP65 for protection in dusty or wet areas
  Dual NPN/PNP outputs for flexible Interface with control systems
  4-pin M8 Terminal offers compact, standard connector compatibility
  Accepts up to 30V DC and draws a maximum of 100mA for low-power operation
  Response time of 0.1ms enables high-speed object sensing
  Operates between -20°C and 60°C for broad industrial temperature ranges

**Applications**

• Suitable for part presence detection on assembly lines
  Ideal for counting small components on high-speed conveyors
  Used with PLC inputs requiring NPN or PNP switching signals
  Can be used for edge detection in packaging machinery
  Suitable for integration into inspection fixtures on test benches

What connector type does it use for wiring?

It employs a 4-pin M8 Terminal for straightforward cabling and compatibility with common industrial harnesses.

How does the sensor handle different switching requirements?

The output supports both NPN and PNP configurations, allowing direct connection to sinks or sources on control devices.

What environmental conditions can it tolerate?

The unit withstands temperatures from -20°C to 60°C and carries an IP65 ingress rating for protection against dust and jets of water.

Which approvals back its suitability for use in regulated installations?

It conforms to recognised standards including EU and UK listings as well as RoHS and cULus approvals.
