Sensing range and mounting
The SICK IM18-08NCP-ZC1 is an M18 inductive proximity sensor with an 8 mm sensing range and a safe operating distance of 6.48 mm. Its non-flush mounting style and cylindrical thread design suit automation tasks where metal targets are detected at close range. The sensor operates on 10 V DC to 30 V DC with a 300 Hz switching frequency. Output logic is wire-configurable between PNP and NPN as well as normally closed or normally open.
Enclosure rating and temperature limits
A nickel-plated brass housing and plastic sensing face meet IP67 protection for dust and water ingress. The unit is rated for ambient temperatures from –25 °C to +70 °C and withstands shock at 30 g for 11 ms plus vibration from 10 Hz to 55 Hz at 1 mm amplitude. Current consumption is 30 mA with a 1.2 V voltage drop and a 200 ms power-up delay.
Continuous load behaviour
Continuous output current is rated at 100 mA with built-in short-circuit, reverse-polarity and power-up pulse protection. Hysteresis stays within 2 % to 10 % and repeatability is held to 5 % across the temperature range. EMC compliance follows EN 60947-5-2 for reliable switching in industrial environments.

Questions about this item
How do I mount the M18 x 1 threaded body without stripping the housing?
Screw the nickel-plated brass barrel into a matching M18 x 1 hole and torque to no more than 40 Nm; the 37 mm thread length gives full engagement without bottoming out on the 74 mm body.
Will the sensing face or the M12 connector need periodic replacement?
The plastic sensing face and the 4-pin M12 plug are both rated IP67 and have no moving parts, so neither requires scheduled replacement under normal –25 °C to +70 °C operation.
At what point does the 300 Hz switching frequency become the bottleneck in a high-speed line?
Each output cycle needs at least 3.3 ms, so if the target passes the 8 mm sensing range in less than that time the sensor cannot reliably switch; the 200 ms power-up delay also blocks instant restarts.
