SICK Optical Photoelectric Sensor, Fork Sensor, 120 mm, NPN/PNP, IP65

SICK Series WF Photoelectric Sensor, 30V Maximum DC Voltage, 100mA Maximum Current - WF120-60B410

This photoelectric sensor is an optical detection device designed for automation environments where reliable object sensing is required. It operates as a fork-style sensor using an infrared light source to detect interruptions in the light path and is built for industrial use with a metal housing and sealed enclosure suitable for exposed installations.

Features & Benefits

• Aluminium housing provides robust protection against mechanical stresses
  IP65 sealing permits use in dusty and splashing conditions
  Infrared LED delivers consistent optical detection performance
  NPN and PNP selectable outputs support diverse control systems
  M8 4-pin connector enables quick, secure electrical connection
  100μs response time suits fast-moving production tasks

**Applications**

• Suitable for part detection on high-speed assembly lines
  Ideal for object counting in packaging machinery
  Used for presence monitoring in pick-and-place systems
  Can be used for edge detection in sheet handling operations
  Suitable for conveyor jam detection and position sensing

What electrical limits must be observed during installation?

The sensor accepts DC supplies up to 30V and draws no more than 100 mA under normal operation so wiring and power supplies should match these limits.

How should the device be connected to control equipment?

Use the supplied M8 4-pin connector to Interface with control inputs, wiring follows standard NPN or PNP logic depending on the chosen output mode.

What environmental temperatures can it tolerate in continuous service?

The unit is rated to operate across a temperature range from -20°C to 60°C, allowing deployment in chilled or warm process areas.

Which test standard relates to mechanical shock resistance?

Mechanical shock performance is assessed in accordance with EN 60068-2-27 demonstrating suitability for environments subject to transient impacts.
