SICK 1066552 GRTE18-P2462 PNP Diffuse Photoelectric Sensor

Technical Overview

The SICK GRTE18-P2462 is an energetic photoelectric proximity sensor with complementary PNP outputs and an axial M18 × 1 cylindrical housing. It evaluates target-reflected light from one mounting side. The sensing range is 10–800 mm and maximum range is 5–1,000 mm on 90% remission reference white. A 650 nm red LED forms a 45 mm spot at 800 mm, while a 270° potentiometer adjusts reception. Response is below 1,000 µs with resistive load, with 500 Hz switching at a 1:1 light/dark ratio. An M12 four-pin male connector connects the IP67 nickel-plated brass/ABS housing; operation spans −25 to +55 °C at supply ≤24 V and output current <50 mA.

Industrial Applications

1. Checking a workpiece in a fixture

An assembly fixture can position the sensor toward the expected face of an opaque workpiece, with clear optical separation from surfaces behind the detection point. Energetic sensing evaluates reflected target light, and the potentiometer sets reception for the installed geometry. Complementary PNP outputs supply the local presence state to the sequence controller.

Problem Solved

A contactless workpiece signal identifies an occupied fixture for the controller, supporting assembly sequencing without a mechanical feeler pressing against the part at the sensing position.

2. Counting separated components on a conveyor

A conveyor can aim the sensor at a position crossed by separated opaque parts so each target presents reflected light to the receiver. The 45 mm at 800 mm optical spot defines the monitored region, while the potentiometer adapts reception to the target and background geometry. The 500 Hz switching frequency supports repeated transitions within the documented timing limits.

Problem Solved

Discrete reflected-light transitions mark individual part passages without contact, giving the controller a count input when the installed geometry separates each target from the empty path.

3. Checking opaque strip continuity

A feeder can direct the sensor toward an opaque strip at a fixed monitoring position so reflected light indicates material present. A break or runout removes the target from that optical position and changes the complementary PNP signals. IP67 protection supports exposed machine mounting, while the M12 four-pin connector provides the electrical connection to compatible machine wiring.

Problem Solved

A change in local material presence provides an electrical indication of interrupted strip feed, helping the controller coordinate a response before additional product enters the affected process section.
