Leuze GS04B/P.1-20-M8.3 Fork sensor
The Leuze GS04B/P.1-20-M8.3 Fork sensor (Part No. 50146161) is a high-precision fork-type optical sensor designed for the detection of very small parts with exceptional accuracy. Featuring a red LED (660 nm) with pulsed signal technology, it ensures outstanding repeatability of 0.02 mm and can detect objects as small as 0.3 mm.Its high switching frequency of 5,000 Hz and ultra-fast 0.1 ms response time make it ideal for high-speed automation processes. Built with a durable diecast zinc housing, glass lens, and IP67 protection, the sensor offers long-term reliability in industrial environments.
The device supports light/dark switching, sensitivity adjustment, and features a clear LED status display. With its M8, 3-pin connector and compact design, installation is quick and secure. The sensor is perfect for packaging machines, sorting systems, robotics, and precision assembly applications requiring high accuracy, stability, and reliable part detection.
Applications
-
High-precision detection of very small parts in packaging, labeling, and assembly automation.
-
Position and presence monitoring in robotics, pick-and-place systems, and semiconductor handling.
-
Edge and object detection for fast-moving materials in printing, textile, and material-processing machines.
-
Quality inspection tasks requiring ultra-fast response time and repeatability for miniature components.
Technical Precautions
-
Ensure clean, unobstructed optical path, as dust or oil can affect detection accuracy for small parts.
-
Maintain correct supply voltage (10–30 V DC) and protect wiring from electrical noise for stable switching.
-
Avoid exceeding the maximum switching current (100 mA) to prevent damage to the transistor output.
-
Install the sensor using a rigid, vibration-controlled mount, as excessive vibration may affect repeatability and switching precision.
