SICK Retroreflective Photoelectric Sensor Barrel Sensor 60 mm to 6 m PNP Output IP67 GRL18S-P2436

The SICK GRL18S-P2436 is a retroreflective photoelectric sensor featuring a compact barrel style housing designed for precise object detection within industrial automation settings. Its detection range spans from 60 mm to 6 m, achieved through a visible red LED light source that ensures accurate sensing over varying distances.

This sensor employs a PNP output type, allowing for simplified wiring and direct interfacing with PLCs. The device supports a wide supply voltage range from 10 V to 30 V DC and offers a rapid response time of 0.5 ms, enabling efficient high-speed detection and counting tasks.

With an IP67 enclosure rating, the sensor is protected against dust ingress and is suitable for wash-down applications, ensuring long-term durability in harsh environments. The housing is constructed of robust ABS plastic, and the optics utilize PMMA plastic materials. Threaded mounting and a 4-pin M12 male connector provide straightforward installation and cabling.

Two front-facing LEDs indicate power (green) and received-light status (yellow), facilitating easy operational monitoring. The sensor operates reliably within an ambient temperature range of −25°C to +55°C, offering versatility across diverse industrial settings.

Additional protections include reverse polarity protection and safeguarded outputs against overcurrent and short circuits, supporting operational safety. The sensor delivers a maximum output current of 100 mA, accommodating a variety of load demands.

Common applications include presence detection on conveyor systems utilizing reflectors, end-of-line packaging verification in automated cells, high-throughput object counting, and part positioning in assembly machinery. It is particularly suited for integration where a compact M18 threaded mounting format is required.
