Checking for live stock

The RS PRO 903-3939 is a high-precision U-shaped (fork-style) through-beam photoelectric sensor crafted for automatic detection of objects interrupting the beam path in compact spaces. With a detection range of 30 mm, NPN switching output (NO/NC), rugged aluminium-alloy housing and IP67 rating, this sensor is designed for critical industrial automation tasks where reliability, fast response and environmental resistance matter.

How It Benefits Users

30 mm detection range for precise short-range object detection.
Through-beam fork-style U-shape design for uninterrupted object path detection.
NPN output with NO/NC switching for flexible circuit design.
IP67 housing ensures dust-tight and water-immersion protection in harsh environments.
Built with a robust aluminium alloy body for durability and long service life.
Infrared LED light source offering low interference from ambient light.
Pre-wired 2 m cable simplifies installation and reduces wiring errors.

Engineered for High-Speed, Reliable Industrial Detection

In fast-moving automation systems, the 903-3939 excels through its ultra-fast response time (less than 0.6 ms) and minimal loading on mechanical assemblies. The fork-style beam path enables tight integration where objects need to pass through an open slot, such as packaging, conveyor systems and material handling.

Typical Uses of this Photoelectric Sensor

Object detection on conveyor or packaging lines where items pass through a slot.
Position monitoring of transparent or small parts in manufacturing automation.
Machine-guarding or safety monitoring where a beam break condition triggers control logic.
Integration in wet, dusty or wash-down environments (IP67 rated).
OEM equipment requiring compact through-beam sensing with a pre-wired connection.
Automation systems using NPN switching logic for PLC or control module integration.
