Sick GL6L-F6212 Photoelectric Sensor

The Sick GL6L-F6212 Photoelectric Sensor utilizes a high-precision laser light source to achieve exceptional retro-reflective sensing performance. Operating with a visible red laser beam at 680 nm, it produces a narrow 3.5 mm light spot at 1,000 mm, enabling accurate detection of small, shiny, or irregularly shaped objects. The sensor is capable of sensing objects up to 12 meters when used with a suitable reflector. Fine adjustments can be made via the integrated potentiometer and mode switch, allowing users to configure sensitivity and switching behavior based on application requirements.

This sensor operates within a voltage range of 10–30 V DC, with low current consumption ≤ 20 mA, making it energy-efficient even in continuous operations. It offers a fast response time of under 625 µs and supports a switching frequency of 1,000 Hz, ensuring high-speed performance in synchronized industrial systems. The PNP digital output is compatible with standard industrial PLCs, while the 4-pin M8 male connector (336 mm cable length) ensures secure and flexible connectivity. Housed in a 12 mm x 31.5 mm x 21 mm rectangular ABS casing, and protected by a PMMA front screen, the sensor is rated IP67 for water and dust resistance. Designed for durability in environments ranging from –20 °C to +50 °C, the GL6L-F6212 is a trusted choice for precise, laser-based object detection.

The Sick WL4S-3F2130 Photoelectric Sensor is ideal for applications where space is tight, and detection accuracy must be high. In fast-moving conveyor lines, this sensor detects objects like caps, trays, or packaged goods—without being affected by background changes or inconsistent lighting. Its visible red light simplifies alignment, especially in narrow or cluttered setups.

Engineers choose this model for its low maintenance and high reliability. Senior technicians benefit from its consistent switching response in harsh or dusty environments, while junior engineers find the plug-and-play setup intuitive for training or field use. The WL4S-3F2130 is commonly used in sectors like FMCG, automotive, and logistics where quick response and detection reliability are critical. It integrates smoothly into PLC-controlled systems and supports seamless automation workflows without complex calibration. Its trust factor comes from Sick’s proven technology, paired with the practical advantages of laser precision and rugged industrial design.
