SICK GRTE18-N1147_1066544 Photoelectric sensor
SICK GRTE18-N1147 enhanced diffuse photoelectric sensor, NPN, part 1066544. Robust short-range presence detection for assembly and fixture monitoring.
Overview
The SICK GRTE18-N1147 (part number 1066544) is an enhanced energetic diffuse photoelectric sensor in the GR18 family with NPN switching output. It provides robust short-range presence detection with high excess gain, suitable for dark targets and dusty assembly environments.
How It Works
The sensor emits strongly driven modulated light and evaluates the reflection from the target. The enhanced optical design returns a strong signal even from dark surfaces, and the output switches when the received light crosses the threshold. The family-typical short operating range concentrates the detection on the immediate target area.
Key Features

Installation and Setup Notes
Install the sensor with the light spot fully on the target and angle it away from glossy surfaces that could cause optical feedback. Adjust sensitivity so the darkest production target switches reliably. In environments with spatter or dust, plan periodic lens cleaning into the maintenance schedule.
Frequently Asked Questions
Which supply scheme suits the NPN output?
NPN outputs switch the load to ground and fit PLC inputs wired for sinking signals, common in many Asian machine designs.
Can it distinguish parts from the fixture surface?
The energetic principle switches on reflection, so a shiny fixture behind a dark part can reflect more light; in that case use background suppression instead.
Is the range adjustable?
The sensitivity is adjustable; the operating range class of the family stays short-range by design.
