The GTE6-P4231 is an energetic photoelectric proximity sensor designed by SICK (Germany) for non-contact object detection at distances up to 900 mm, distinguished by its PinPoint LED red light source, selectable PNP light/dark switching output, and IP67 protection rating.
Overview of the SICK GTE6-P4231 Photoelectric Sensor
The GTE6-P4231 is an energetic photoelectric proximity sensor belonging to the G6 product family – SICK’s miniature photoelectric sensor line engineered for object detection in confined spaces. The sensor operates on the diffuse reflection principle, emitting a 650 nm visible red PinPoint LED beam and detecting reflected signals from target surfaces.
Its compact ABS/PC plastic housing (12 × 31.5 × 21 mm), IP67 rating, and five-turn mechanical spindle sensitivity adjustment make it straightforward to install across a wide range of industrial environments. It is widely deployed in electronics manufacturing, food and beverage, pharmaceutical processing, and automated conveyor systems.

Industrial Applications of the GTE6-P4231 Photoelectric Sensor
With a sensing range of up to 900 mm, the SICK GTE6-P4231 is suitable for a broad range of automated object detection applications in Vietnamese factories:
- Conveyor & logistics systems: Detects parcels and products on conveyors, triggering sorting or counting routines. The 500 Hz switching frequency supports detection of fast-moving objects.
- Electronics & semiconductor manufacturing: Detects small components, PCBs and connectors on SMT assembly lines. The PinPoint LED spot of Ø 5 mm delivers high detection accuracy for small targets.
- Food & beverage industry: IP67 rating withstands low-pressure water washdowns. The sensor detects bottles, cartons and pouches on packaging lines.
- Pharmaceutical production: Controls product presence and counting on high-speed conveyor lines while meeting cleanroom environmental requirements.
- Machine automation: Integrates easily with PLC systems via the standard PNP output, with flexible sensitivity adjustment via the built-in spindle.
