SICK 1069122 GRTE18S-P2467 PNP Diffuse Photoelectric Sensor

Technical Overview

The SICK GRTE18S-P2467 is an energetic photoelectric proximity sensor with axial optics in a short M18 × 1 plastic housing. It provides 10–800 mm sensing and a separately listed 5–1,000 mm maximum range on 90% remission reference white. A 650 nm red LED forms a 45 mm spot at 800 mm, and a 270° potentiometer adjusts the reflected-light sensing condition. Complementary PNP outputs provide light/dark states through an M12 four-pin male connector. Response is below 1,000 µs with resistive load and switching frequency is 500 Hz at a 1:1 light/dark ratio. ABS housing, PMMA optics, two fastening nuts and green/yellow indicators accompany IP67 protection and stated supply/load/temperature limits.

Industrial Applications

1. Detecting an article arriving at a loading station

A loading station can aim the sensor at an opaque article surface and read a PNP transition when it arrives. Energetic sensing evaluates reflected light from one mounting side, and the 270° potentiometer adapts detection to the installed target. Commissioning uses actual surface remission and distance, with darker materials assessed against their shorter documented ranges.

Problem Solved

One-sided optical detection gives external sequence logic an article-arrival reference, helping coordinate loading without a receiver or reflector installed across the working space.

Article arrival Adjustable sensing PNP output

2. Counting separated opaque packages on a conveyor

A feed conveyor can move separated opaque packages through the optical field and send PNP transitions to external counting logic. The 500 Hz rating and response below 1,000 µs define the timing basis. Commissioning checks package coverage, remission and spacing at the installed distance, using the 45 mm spot specification at 800 mm when assessing the target presentation.

Problem Solved

Distinct target transitions give external counting electronics package-passage events, helping track separated loads with a short cylindrical sensor installed from one side of the conveyor.

Package count 500 Hz Red LED

3. Comparing complementary signals during ordinary input diagnostics

A fixture can connect Q and complementary Q to two ordinary controller inputs and compare their settled states during a known article-presentation cycle. Both PNP outputs derive from the same reflected-light condition. External diagnostic logic accounts for switching transitions before recording an unexpected input relationship for maintenance review, while the green and yellow indicators provide local power and presence context.

Problem Solved

Opposing output observations give ordinary external diagnostics a reference for recognizing an inconsistent input relationship, helping focus maintenance on wiring or input-reading faults.
