Leuze PRK5B.M1/2 Photoelectric Sensor
The Leuze PRK5B.M1/2 Photoelectric Sensor (Part No. 50149300, PRK5BM12) from the Series 5B is a compact and reliable photoelectric retro-reflective sensor designed for industrial object detection. It uses a 645 nm red LED with a pulsed transmitted signal for dependable sensing.With the TK(S) 100x100 reflector, it provides a guaranteed operating range of 0.03 to 4.5 m and a typical range up to 6 m. The sensor features an NPN transistor switching output, 500 Hz switching frequency, and a fast 1 ms response time.
Sensitivity can be conveniently adjusted using the 270° potentiometer. Its IP67 protection, PC-ABS housing, and wide operating temperature range of -40°C to +60°C make it suitable for demanding environments. The compact 11 × 32.4 × 20 mm housing enables easy installation in space-limited machinery.
Applications
-
Object presence and position detection on automated conveyor systems.
-
Product counting and monitoring in packaging and manufacturing lines.
-
Material handling and sorting applications requiring reliable photoelectric detection.
- Machine automation systems operating in demanding industrial environments.
Technical Precautions
- Use the recommended TK(S) 100x100 reflector and maintain proper alignment for reliable detection.
- Supply the sensor with 10–30 V DC, ensuring residual ripple remains within the specified limit.
Adjust the 270° sensitivity potentiometer carefully according to the target and operating distance.
- Tighten M3 mounting fasteners to the recommended 0.9 N·m torque and avoid excessive mechanical stress on the cable.
