Sick GL6L-P1211 Photoelectric Sensor

The Sick GL6L-P1211 Photoelectric Sensor (G6 Series) is a laser retro-reflective model specified for long, stable detection up to 12 m (max), using visible red 680 nm light for a tight 3.5 mm spot at 1 m. It runs on a 10–30 V DC supply with a PNP digital output, achieving ≤ 625 µs response and 1,000 Hz switching frequency for high-speed lines. A robust IP67 ABS/PC housing and PMMA front screen protect optics and electronics, while a 2 m, 3-wire cable simplifies integration in control panels and compact machines typical of India’s industrial automation landscape.

In packaging systems and conveyor logistics, the GL6L-P1211’s laser spot helps detect small targets, label edges, and narrow features at longer distances without sacrificing repeatability. Across electronics assembly and automotive sub-lines, its fast response supports part presence checks, tray positioning, and pick verification. For machine builders in India, the combination of PNP output, compact 12 × 31.5 × 21 mm housing, and IP67 sealing ensures reliable operation near dust, splashes, or cleaning routines. Typical benefits include stable detection on challenging surfaces, simplified alignment through the visible laser spot, and consistent switching on high-throughput conveyors where downtime and misreads are costly.

Engineered by Sick, a recognized authority in industrial sensors, the GL6L-P1211 reflects quality and reliability expected from ISO-aligned manufacturing. The mechanical design balances rigidity and light weight, while the optical path and electronics maintain signal integrity under vibration and temperature shifts (–20 °C to +50 °C operation). Field technicians value the adjustable potentiometer / mode switch for pragmatic setup, and controls engineers appreciate clean integration with PLC input cards via the PNP output. Backed by Sick’s documentation and support practices, this model fits standardized maintenance programs and repeatable OEM designs.

The Sick GL6L-P1211 Photoelectric Sensor combines 12 m laser reach, tight spot geometry, and 1,000 Hz switching in a compact, IP67 package—delivering accurate, durable detection for packaging, electronics, and conveyor automation. Its PNP output, 10–30 V DC supply, and fast response streamline commissioning and scaling across multi-line facilities. Backed by Sick’s support network, the GL6L-P1211 is trusted by engineers for consistent performance.
