SICK Retroreflective Photoelectric Sensor, Barrel Style, 60 mm to 6 m Detection Range, PNP Output, Threaded GRL18S-P2438

SICK GRL18S-P2438 is a retroreflective Photoelectric Sensor featuring a barrel sensor style with a cylindrical ABS enclosure. It provides reliable object detection over a range of 60 mm to 6 meters using a reflector. Designed for industrial automation, this sensor offers PNP output and connects through a 4-pin M12 male connector, making it ideal for panel and machine integrations where space efficiency and ruggedness are necessary.

The sensor includes a visible red LED light source for accurate target detection and a response time of 0.5 ms suitable for high-speed tasks. It operates between 10 V to 30 V DC supply voltage and has an IP67 rating ensuring robust protection against dust and water ingress, making it well suited for harsh manufacturing and processing environments.

This unit features two front LEDs: a green LED indicates power supply presence, and a yellow LED signals beam reception status, which switches off when an object is detected. It is mounted using M18 threaded fixtures and comes supplied with fastening nuts. Complementary mounting brackets and plug cables are available to facilitate installation.

The sensor is engineered with reverse polarity protection and overcurrent/short-circuit protection on outputs to prevent damage during industrial operations. Its 100 mA maximum output current allows direct interfacing with downstream PLC inputs requiring PNP signaling.

Applications include object presence detection on conveyor lines, pick-and-place verification on automated assembly lines, and alignment checks in material handling. Its CE and cULus certifications confirm compliance with industry safety standards.
