SICK Energetic Photoelectric Sensor, Barrel Sensor, 10 mm → 400 mm Detection Range, PNP Output, IP67 Metal GRTE18S-P2442

SICK GRTE18S-P2442 Energetic Photoelectric Sensor is a compact cylindrical barrel sensor designed for precise object detection in industrial automation applications. It features a visible red LED light source enabling energetic detection over a range of 10 mm to 400 mm, making it ideal for high-speed conveyor and packaging line applications requiring rapid sensing and robust performance.

This sensor provides a fast 1 millisecond response time and uses a PNP complementary output that supports both light and dark switching, allowing flexible integration to PLCs and automation systems. The sensor housing is made of stainless steel (V4A/1.4404 316L), ABS, and brass materials, offering excellent resistance to wash-down and hygienic zone requirements with an IP67 ingress protection rating.

Installation is simplified with a threaded mount and a standardized 4-pin M12 connector for reliable electrical connection. It operates within a temperature range from -25 °C up to +55 °C and withstands temporary immersion and wash-down conditions, including IP68 and IP69K ratings. To ensure safe operation, the sensor circuitry incorporates reverse-polarity protection and safeguards against output short-circuit and overcurrent faults.

The detection range can be fine-tuned on-site using a 270° potentiometer, enabling users to adapt sensing distance based on target reflectivity and size. Visual indication of operation includes a green LED for power and a yellow LED to show detected presence or absence of objects. This sensor is commonly employed for fast part detection on high-speed conveyors, food processing machinery, automated packaging, and presence sensing of reflective and non-reflective items in both industrial and laboratory environments.
