Sick M8 Inductive Sensor NPN NC

The Sick IM08-02BNO-ZTK is a cylindrical inductive proximity sensor with an M8 × 1 thread and a short 40 mm metal housing. It detects metal targets at a 2 mm sensing range with a 3,000 Hz switching frequency. The sensor provides an NPN normally-closed output on a 3-pin M8 connector and operates on 10–30 V DC. It is built for automation and machine-building tasks that require flush mounting in tight spaces.

Replaces larger or slower sensors in constrained

This short-body M8 unit fits where longer barrels or wider threads cannot, and its 3,000 Hz switching frequency supports faster cycle rates than lower-frequency alternatives. The upgrade is worth it when an application demands flush mounting in an M8 thread, a 2 mm sensing range, and an IP67-rated metal housing that withstands 30 g shock and vibration from –25 °C to +70 °C. It also supplies reverse-polarity and short-circuit protection for wiring safety.

Check thread size voltage

Verify that the mounting hole matches the M8 × 1 thread with a 25.3 mm usable thread length and that the tightening torque does not exceed 4 Nm. Confirm the control system accepts an NPN normally-closed signal on a 3-wire DC circuit and that the supply voltage stays within 10–30 V DC with ripple below 10 %. Ensure the 3-pin M8 connector pinout matches the existing cable harness.

Questions about this item

What thread size does the M8 sensor need for mounting?

The sensor uses an M8 x 1 thread with a 25.3 mm thread length and a maximum tightening torque of 4 Nm.

How is the flush sensor wired and what is a common mistake?

Connect the 3-pin M8 connector using DC 3-wire wiring for 10–30 V DC supply; a common mistake is reversing polarity despite built-in protection.

What maintenance does the IP67-rated sensor need over time?

Periodically check the nickel-plated brass housing and plastic sensing face for damage, and verify the connector seal remains intact to maintain IP67 protection.
