The GTB2S-P1331 Sick 3 mm Light Spot Photoelectric Sensor is a compact photoelectric proximity sensor designed for precise short-range detection in industrial automation. The GTB2S-P1331 Sick 3 mm Light Spot Photoelectric Sensor operates with background suppression, 5–30 mm sensing range, PNP switching output, and a visible red PinPoint LED. It is part of the GTB series and is commonly integrated into automated machinery and control systems.
This photoelectric sensor is used in conveyors, packaging machines, small-part handling, and assembly automation where accurate detection is required. The focused Ø 3 mm light spot supports detection of small objects, while the <0.6 ms response time allows stable operation in fast-moving processes. IP67 protection and fixed optical alignment help maintain consistent output in typical industrial environments.
The Sick GTB2S-P1331 photoelectric sensor combines defined optical behavior with stable electrical characteristics for industrial use. With 10–30 V DC supply, 800 Hz switching frequency, and compact ABS housing, it aligns with standard automation requirements. Supported by Sick sensor engineering and the GTB series design, GTB2S-P1331 remains suitable for reliable short-distance sensing across industrial automation applications.
