Sick GRTE18-N1142 cylindrical photoelectric sensor
The Sick GRTE18-N1142 is a cylindrical photoelectric proximity sensor with an M18 x 1 threaded metal housing. It operates on 10 V DC to 30 V DC supply voltage and provides an NPN complementary switching output with light/dark switching via potentiometer adjustment. The sensor connects through a 4-wire PVC cable measuring 2 m in length and carries an IP67 enclosure rating.
Suits automation tasks needing axial red-light
This sensor fits applications that require visible red PinPoint LED detection with a 9 mm spot size at 400 mm distance and a 500 Hz switching frequency. Buyers who need a PNP output type or a connector-based termination instead of a fixed cable should look at other models. The operating temperature range of –25 °C to +55 °C covers typical industrial environments.
NPN output with 100 mA maximum load current
The switching output delivers NPN signalling with a maximum output current of 100 mA and a response time below 1 000 µs. Signal voltage for NPN HIGH/LOW is approximately the supply voltage or equal to 3 V. These electrical limits determine whether the sensor can drive the intended load directly or requires an interface relay.

Questions about this item
What supply voltage must the installation provide for the GRTE18-N1142 sensor?
The sensor operates on 10 V DC to 30 V DC, so the system must deliver a DC supply within that range.
Will the M18 x 1 thread and 2 m PVC cable fit the existing mounting holes and wiring loom on my machine?
The housing uses an M18 x 1 thread with two fastening nuts supplied, and the 4-wire PVC cable is 2 m long for direct termination.
How can I verify the NPN complementary output is switching correctly after wiring?
Measure the signal voltage at the output; it should read approximately the supply voltage in the HIGH state and drop to 3 V or less in the LOW state when the target enters the 10 mm to 400 mm sensing range.
