Sick IME18-08NPSZC0S Inductive Proximity Sensor 8 mm M18 PNP M12 4-pin

Sick IME18 inductive proximity sensor

The Sick IME18-08NPSZC0S is an inductive proximity sensor with a cylindrical M18 × 1 metal housing. It detects metal targets at a sensing range of 8 mm and provides a PNP normally-open output through an M12 4-pin male connector. The unit operates on 10 V DC to 30 V DC and is rated IP67 for dust and water resistance. It suits industrial automation tasks that require non-contact metal detection.

Verify voltage wiring and mounting clearance

Confirm that your control system supplies 10 V DC to 30 V DC and can accept a PNP normally-open signal with a 2 V voltage drop. The sensor draws 10 mA and delivers up to 200 mA continuous current with short-circuit, reverse-polarity and power-up pulse protection. Ensure the M12 4-pin connector pinout matches your cable. The non-flush mounting style needs space in front of the 18 mm sensing face and a maximum tightening torque of 40 Nm on the M18 thread.

Ideal for metal detection in harsh environments

This sensor fits machines that need reliable metal detection at 8 mm range with a 1 000 Hz switching frequency and ±10 % temperature drift. The nickel-plated brass housing and PA 66 sensing face withstand –25 °C to +75 °C ambient temperatures and 30 g shock. It is not suited for applications requiring flush mounting, NPN output, analog signals, longer sensing distances or AC supply voltages. Buyers needing different thread sizes or connector types should consider other models.
