SICK Fork Sensor Photoelectric Sensor, Fork Sensor

SICK Series WF Photoelectric Sensor, Aluminium Housing, IP65 - WF30-40B410

This photoelectric sensor is a fork-style detector designed for label sensing and similar object recognition tasks within automated systems. It operates using an infrared LED and is housed in aluminium with ingress protection suited to industrial settings. The device connects via a four-pin Terminal and is intended for installation where compact, non-contact detection is required.

Features and Benefits:

• Response time 100μs delivers Rapid detection for high-speed lines
  Output selectable NPN or PNP enables flexible control integration
  Rated up to 30V DC and 100mA supports common control circuits
  Operating range -20 to 60°C allows use in varied ambient conditions
  IP65 protection ensures resistance to dust and low-pressure water jets
  Complies with EN60068-2-27 to withstand mechanical shock testing

Applications

• Suitable for label detection on packaging conveyors
  Ideal for edge sensing in automated labelling machines
  Used with pick-and-place equipment for presence verification
  Can be used for printing registration checks in web handling

What electrical connector is provided for installation?

A four-pin Terminal is supplied to make straightforward wiring to control systems and simplifies replacement on existing mounts.

How does the housing material affect mounting and longevity?

The aluminium construction offers mechanical robustness and aids heat dissipation, improving suitability for industrial mounting options.

Can it operate in environments with occasional water exposure?

With an IP65 rating the unit resists dust ingress and low-pressure water jets but is not intended for continuous immersion.

How is detection achieved for thin media such as labels?

The fork geometry combined with an infrared LED creates a reliable interruption beam that is well suited to sensing thin, semi-translucent materials.
