The Sick GL6-P6211 Photoelectric Sensor operates on a retro-reflective sensing principle with a dual lens design that ensures consistent object detection up to 5 meters, with a maximum sensing capability of 6 meters. It uses a PinPoint LED to emit visible red light at 650 nm, forming a focused 8 mm light spot at 350 mm, ideal for identifying small parts or labels even in fast-moving automation lines. The integrated 270° potentiometer allows users to fine-tune the sensor’s response threshold for flexible deployment in varying lighting and environmental conditions.
Operating on a 10–30 V DC power supply with ±10% ripple tolerance, this sensor consumes just 30 mA and supports PNP digital output with light/dark switching modes that can be toggled using an onboard selector switch. Its high-speed performance is backed by a response time under 625 µs and a switching frequency of 1,000 Hz, ensuring real-time object detection in synchronized production environments. The sensor is housed in a durable ABS/PC rectangular body (12 mm x 31.5 mm x 21 mm), features a 4-pin M8 male connector, and is rated IP67 for reliable operation in dusty or wet environments. It remains fully functional across an ambient temperature range of –25 °C to +55 °C. Backed by Sick’s proven performance in industrial sensing, the GL6-P6211 is a trusted choice for compact, high-precision detection needs.
The Sick WL4S-3F2130 Photoelectric Sensor is widely used in systems where precision, speed, and minimal footprint are essential. It’s a popular choice in conveyor-based packaging lines and robotic work cells, where background reflection is unpredictable, and compact installation is necessary. The visible red LED helps engineers align the sensor quickly and reduce setup time.
For maintenance professionals, it ensures reliable switching and low downtime. Senior technicians appreciate the robust IP67 housing for demanding industrial conditions, while engineering trainees can easily understand its wiring and configuration during real-world hands-on learning. This model performs consistently in material detection, part counting, label verification, and edge detection—making it a staple across FMCG, automotive, and electronics manufacturing plants. With Sick’s legacy of innovation, the WL4S-3F2130 delivers dependable sensing where precision can't be compromised.
