Sick GL6-F2411V Photoelectric Sensor

The GL6-F2411V Photoelectric Sensor by Sick combines cutting-edge optics with a dual-lens retro-reflective design, offering a reliable sensing range from 0.07 meters up to 5 meters. Equipped with a PinPoint LED light source emitting visible red light at 650 nm, it ensures accurate and consistent detection even in challenging industrial lighting conditions. The sensor features a sharply focused Ø 8 mm light spot at 350 mm, allowing for high-precision positioning and alignment of reflective targets. With a broad supply voltage range of 10–30 V DC and low current consumption of 30 mA, the GL6-F2411V supports energy-efficient integration into modern control panels. The PNP output and light/dark switching mode make it suitable for interfacing with a wide range of PLCs and industrial controllers. Response times are minimized with a rapid ≤ 625 µs switching speed and up to 1,000 Hz frequency, making it ideal for fast-moving conveyor systems and high-speed automation tasks. Its compact 15 mm x 44 mm x 22 mm rectangular housing is built from corrosion-resistant stainless steel (V4A 316L), while the PMMA front screen ensures long-term optical stability. The sensor carries both IP67 and IP69K enclosure ratings, providing excellent resistance to water, dust, and high-pressure washdowns — a critical requirement in food, pharma, and automotive sectors. The 4-wire, 2-meter cable enables flexible installation in dense or distributed sensor networks. Trusted by engineers globally, the GL6-F2411V represents the intersection of German precision, rugged durability, and high-speed performance.

The Sick Photoelectric Sensor WL4S-3F2130 is commonly used in industrial automation where contactless, reliable object detection is critical. On conveyor systems, it accurately detects the presence of packages or parts—even small or glossy objects—without requiring physical contact. In packaging lines, it verifies item alignment before sealing or labeling, reducing product rejection and downtime. For Indian maintenance engineers, this sensor’s combination of fast response time and rugged IP-rated housing makes it dependable for harsh industrial conditions. Its ease of installation and clear indicator lights help technicians quickly validate sensor function. Engineering students and trainees also find this model useful in practical labs due to its visible red light and real-time switching behavior, helping them understand how object detection works in real-world plants. Whether you're troubleshooting in a factory or designing a control system, the WL4S-3F2130 ensures performance, stability, and confidence in automation.
