Sick GL6-P3212 Photoelectric Sensor

The GL6-P3212 from Sick is a high-performance photoelectric retro-reflective sensor with a dual-lens design that ensures consistent signal reception even when detecting difficult surfaces like transparent or shiny objects. It operates over a sensing range of ≤ 5 m, with a maximum range of ≤ 6 m when paired with a suitable reflector. A PinPoint LED emits a visible red light at 650 nm wavelength, delivering a focused Ø 8 mm light spot at 350 mm for accurate alignment during setup. Engineered for fast-paced industrial lines, it supports a swift response time of ≤ 625 µs and a high switching frequency of 1,000 Hz, making it suitable for high-speed conveyor systems and automated machinery. The integrated light/dark switching mode can be selected using the onboard 270° potentiometer, offering precise control over sensing logic. Powered by a 10 V to 30 V DC supply and consuming just 30 mA, this sensor ensures energy efficiency and stable performance in continuous operation. Its compact rectangular housing (12 mm x 31.5 mm x 21 mm) is constructed from durable ABS/PC plastic, with a PMMA front screen and an IP67 enclosure rating, offering solid resistance against dust, water, and oil mist. The M8, 3-pin connector ensures quick plug-and-play installation in modern industrial panels. With proven performance and robust build quality, the Sick GL6-P3212 is a trusted choice for automation engineers across packaging, logistics, and production environments.

The Sick WL4S-3F2130 Photoelectric Sensor is widely used in industries where reliable detection of objects—regardless of size, shape, or color—is critical. For instance, in food packaging lines, it helps verify the presence of packets before sealing. In automotive assembly, engineers use this sensor to detect small metal or plastic components moving on high-speed conveyor belts. Its visible red light and compact housing make alignment easy, even for first-time users. Indian maintenance teams prefer this model due to its long service life, plug-and-play connector, and consistent detection in dusty or humid factory conditions. Engineering students often study this sensor as a reference for understanding light-based object detection, switching modes, and response time calculations. The ability to switch between light and dark modes makes it flexible for different backgrounds and target surfaces. As automation demands grow, the WL4S-3F2130 remains a reliable, cost-effective sensor trusted for precision, speed, and durability. It’s an ideal fit for anyone—from field technicians to design engineers—who values accuracy and low maintenance in sensing solutions.
