Product Description
SICK GRL18SG-F2337 Photoelectric Sensor
The SICK GRL18SG-F2337 (Part Number: 1059553) is a highly reliable retro-reflective photoelectric sensor from the GR18S product family. Designed for robust industrial automation applications, it offers a versatile scanning range of 0.06 to 6 meters, which is extendable up to 7.2 meters when paired with a PL80A reflector. Featuring a PNP Dark-On (D.ON) output and adjustable sensitivity, this sensor ensures precise object detection across a wide operating temperature range of -25°C to +55°C. Its compact cylindrical design, combined with excellent temperature stability, makes it an ideal choice for packaging, material handling, and general factory automation systems.
