SICK Retroreflective Photoelectric Sensor, Barrel, 60 mm to 6 m Detection Range, PNP Output, IP67, GRL18S-P2431

SICK GRL18S-P2431 Retroreflective Photoelectric Sensor is a cylindrical barrel sensor designed for industrial automation applications requiring contactless object detection. It employs visible red LED light with a detection range from 60 mm to 6 m, delivering reliable performance in demanding environments.

The sensor features a fast response time of 0.5 milliseconds, enabling quick switching operations necessary for conveyor systems, packaging machinery, and inspection stations. Its PNP output allows direct sourcing to programmable logic controller (PLC) inputs for seamless integration.

Built with a durable housing made of metal, ABS, and nickel-plated brass, this sensor achieves an IP67 protection rating, allowing it to withstand dust ingress and temporary immersion in water. The threaded mounting and 4-pin M12 connector facilitate easy installation and reliable connections in automation setups.

Operating within a voltage range of 10 to 30 V DC and capable of output currents up to 100 mA, it can drive small loads directly. It functions effectively across a temperature range from -25 °C to +55 °C and includes two status LEDs: a green one indicating power and a yellow one showing the received beam condition.

This SICK sensor is ideal for tasks such as presence detection on conveyor belts, web edge monitoring with retroreflective targets, object counting in packaging lines, and safety interlock applications that require non-contact sensing. Its high accuracy and robust design make it an excellent choice for industrial, manufacturing, packaging, and automation systems.

The sensor uses visible red LED light for accurate object detection at a distance. It offers a fast response time of 0.5 ms suitable for high-speed switching. PNP output enables straightforward connection to PLC inputs. The IP67-rated enclosure makes it resistant to dust and moisture for industrial use.

It supports an operating voltage range from 10V to 30V DC. The housing is made of metal, ABS, and brass with a threaded mount. Equipped with a 4-pin M12 connector for easy integration. Operates reliably in temperatures from -25°C to 55°C.

Indicator LEDs provide power and beam reception status. Suitable for conveyor part detection, packaging machinery, and safety interlocks. Explore the wide range of Photoelectric Sensors at EnvMart for high-quality automated sensing solutions.
