SICK 1067974 GRTE18-P1167 M18 PNP Diffuse Photoelectric Sensor

Technical Overview

The SICK GRTE18-P1167 is an energetic photoelectric proximity sensor with axial red-LED emission in an M18 ×1 cylindrical plastic housing. Its sensing range is 10–800 mm on the specified 90% remission white target, with a 5–1,000 mm maximum range; darker targets have shorter documented ranges. A 270° potentiometer adjusts sensitivity, while complementary PNP outputs provide light and dark switching signals. The 650 nm LED produces a 45 mm spot at 800 mm, with response below 1,000 µs and 500 Hz switching under the stated test conditions. A 2 m four-wire PVC cable, two mounting nuts, ABS housing and PMMA optics complete the IP67 sensor.

Industrial Applications

1. Confirming a part in a one-sided assembly fixture

An assembly fixture can aim the sensor at the exposed face of a component and send its complementary PNP signals to external sequencing inputs. Energetic sensing uses light returned from that face, so the arrangement does not require a receiver on the opposite side. The fixture fixes target position and surface presentation within the relevant white, gray or black target range.

Problem Solved

Reflected-light detection provides external sequencing with a component-presence condition, helping confirm that a presented part occupies the fixture before the next machine step.

Fixture presence One-sided sensing PNP outputs

2. Counting separated opaque packages at a conveyor side

A conveyor can present separated opaque packages past the axial beam and send each returned-light transition to an external counter. The 270° potentiometer adapts sensitivity to the actual package surface and working distance. Package coverage, spacing and speed determine usable events within the documented response below 1,000 µs and 500 Hz light/dark switching conditions.

Problem Solved

Repeated reflected-light transitions give the external counter discrete package-passage events, helping track separated loads when their surfaces and spacing produce distinct detection intervals.

Package passage 500 Hz Sensitivity adjustment

3. Watching strip continuity above a non-reflecting gap

A feed station can aim the sensor at an opaque strip spanning a non-reflecting opening and use loss of returned light as a discontinuity event. External machine logic interprets that event during the feed sequence. Sensitivity and standoff are set for the actual strip surface, and the opening geometry keeps surrounding structure outside the intended reflected-light presentation.

Problem Solved

A loss-of-return event gives external feed logic a strip-absence reference, helping identify a break or exhausted material presentation before the next processing operation.
