SICK WFS3 Series Fork Sensor, Polyamide Housing, IP65 - WFS3-40N415

This fork sensor provides non-contact object detection in automation and electronics assemblies. It operates as an infrared-based through-beam device mounted on panels to sense small targets passing through its slot. Designed for industrial environments, it combines a Compact polyamide frame with visible LED indication to aid installation and routine checks.

Features and Benefits:

• Infrared LED emitter for consistent detection performance
• 3mm maximum detection to identify fine or thin targets
• 10 kHz switching frequency for high-speed object tracking
• NPN output to Interface with common control systems
• IP65 ingress protection for dust and water resistance
• 4‑pin M8 connector enabling secure panel connections

Applications

• Suitable for counting small components on high-speed conveyors
• Ideal for edge detection of printed circuit assemblies
• Used for part-presence sensing in pick-and-place machines
• Can be used for label-gap detection in packaging lines
• Suitable for monitoring thin materials in web processing

What electrical limits must be observed when wiring the device?

Supply voltage must not exceed 30V and load current must remain at or below 100 mA to prevent circuit stress.

How does the sensor perform across temperature variations?

It operates across a −20 to 60 °C range, maintaining switching behaviour for typical industrial ambient conditions.

What connector and mounting provisions are provided?

A 4‑pin M8 connector is fitted for electrical termination and the unit is configured for panel mounting to simplify integration.

Which indicators assist during setup and troubleshooting?

An onboard LED status display shows operating and detection states to speed alignment and diagnostics.
