Sick IM12-04BNS-ZCK Cylindrical Inductive Sensor M12 NPN NO 4mm Flush IP67

SKU CH-S2RM-2GHPB

Flush-mount M12 inductive sensor detects metal at 4 mm with NPN normally-open output, IP67 housing, and 2,000 Hz switching speed

  • 4 mm flush sensing range detects metal targets reliably
  • 2,000 Hz switching frequency supports high-speed automation cycles
  • IP67 enclosure rating withstands water and dust ingress
  • 10–30 V DC supply voltage fits standard industrial power rails
  • Nickel-plated brass housing resists mechanical wear in harsh environments

Cylindrical M12 inductive sensor

The Sick IM12-04BNS-ZCK is a flush-mount cylindrical inductive sensor with an M12 x 1 thread and a 12 mm diameter. It operates on 10 to 30 V DC with an NPN normally-open output and a 4 mm sensing range. The housing is nickel-plated brass with a plastic sensing face and meets IP67 enclosure rating. A 4-pin M12 male connector provides the DC 3-wire connection.

Sustained-load behaviour

Continuous load current is rated at 300 mA with a voltage drop of 1.5 V and current consumption of 10 mA. Switching frequency reaches 2,000 Hz and hysteresis ranges from 1 to 15 percent. The unit withstands shock at 30 g for 11 ms and vibration from 10 to 55 Hz at 1 mm amplitude. Operating temperature spans –25 °C to +75 °C and EMC compliance follows EN 60947-5-2.

Pre-installation checks

Verify that the mounting location accepts an M12 x 1 thread with 35 mm thread length and 52.2 mm overall housing length. Confirm the control system can read an NPN normally-open signal from a 4-pin M12 connector. Ensure the supply stays within 10 to 30 V DC with ripple below 10 percent. Check that tightening torque does not exceed 7 Nm.

Questions about this item

How much heat or electrical noise does the IM12-04BNS-ZCK generate when running continuously on a 24 V DC supply?

The sensor draws 10 mA with a 1.5 V drop, dissipating only milliwatts, and meets EN 60947-5-2 EMC limits, so heat and electrical noise are negligible in continuous operation.

Which mating cable or connector must I already have to wire the 4-pin M12 plug on this sensor?

You need a 4-pin M12 female cordset wired for DC 3-wire NPN loads, rated for 10–30 V DC and at least 300 mA continuous current.

Will the M12×1 thread and 35 mm thread length fit the same mounting bracket I use for older M12 flush sensors?

Yes — the housing uses a standard M12×1 thread with 35 mm thread length and 52.2 mm overall length, matching the common flush-mount envelope used by legacy M12 inductive sensors.
