Sick GL6-P0111S61 Photoelectric Sensor

The Sick GL6-P0111S61 Photoelectric Sensor offers exceptional detection capability using a dual-lens retro-reflective sensing principle. With a maximum sensing range of 7.2 meters and a typical operating range up to 6 meters, it ensures accurate detection across long distances, even in dusty or complex environments. The integrated PinPoint LED emits visible red light at 650 nm, producing a focused 8 mm light spot at 350 mm—ideal for recognizing small parts or reflective labels with minimal setup time. This model comes factory calibrated with no manual adjustment required, making it fast and error-proof to deploy in production environments.

Engineered to operate on a 10–30 V DC supply, the sensor maintains a low 30 mA current consumption and supports PNP output logic with selectable light/dark switching. It delivers rapid performance with a response time under 625 µs and a switching frequency of 1,000 Hz, enabling seamless integration into fast-paced automation systems. The sensor's ABS/PC housing (12 mm x 31.5 mm x 21 mm) is sealed to IP67 standards, ensuring protection in harsh environments, while its 3-meter cable with M8 4-pin connector and knurled nuts guarantees secure connectivity in industrial setups. Operational in temperatures ranging from –25 °C to +55 °C, this model is trusted across industries for high-speed, long-distance object detection.

The Sick WL4S-3F2130 Photoelectric Sensor is well-suited for fast-moving industrial applications that require compact design and reliable detection. It performs accurately in tasks like part presence detection, label verification, and object positioning on high-speed conveyors. Its visible red light and stable switching help reduce false triggers caused by background reflections or poor lighting.

Maintenance engineers value its IP67-rated housing and rapid response time, which reduce downtime and ensure production continuity. For younger technicians and engineering students, its clear beam and simple wiring make it easy to learn and use. The WL4S-3F2130 integrates well into PLC-based control systems in industries like FMCG, electronics, and precision assembly, where consistent detection is crucial. Trusted for its compact footprint and proven reliability, it is a go-to model for those seeking dependable and maintenance-free photoelectric sensing.
