Cylindrical nickel-plated brass sensor M18 thread 50 mm long with black PA66 sensing face and M12 4-pin connector

Sick

Sick IME18-05BNSZCOK Inductive Proximity Sensor NPN M18 5 mm

SKU CH-HCDF-79DZE

An M18 flush-mount inductive sensor detects metal at 5 mm with NPN normally-open output and an IP67-rated nickel-plated brass housing

  • Flush mounting suits tight spaces with M18 × 1 thread
  • 5 mm sensing range detects metal targets reliably
  • NPN normally-open output simplifies PLC wiring
  • IP67 rating withstands water and dust ingress
  • 10–30 V DC supply fits standard industrial power

Industrial sensing fit

The Sick IME18-05BNSZCOK is a cylindrical M18 inductive proximity sensor with a 5 mm sensing range and NPN normally-open output. Its short nickel-plated brass body measures 50 mm overall with a 33 mm thread length and a 4-pin M12 connector. The unit operates on 10 to 30 V DC and is rated IP67 for harsh environments.

Upgrade from limited-range sensors

This model replaces sensors that cannot detect targets at 5 mm or that lack the 1,000 Hz switching frequency needed for fast automation cycles. The flush mounting style and 4.05 mm safe sensing range suit applications where precise, repeatable triggering is required. It is not suited for buyers who need longer detection distances or analog output variants.

Steady-operation reliability

Hysteresis of 5 to 15 percent and reproducibility of 2 percent keep switching points stable during continuous runs. Temperature drift stays within ±10 percent across –25 °C to +75 °C. The housing withstands 30 g shock and 10 to 55 Hz vibration at 1 mm amplitude. Short-circuit, reverse-polarity and power-up pulse protections guard the 200 mA continuous output.

Questions about this item

What thread size and housing length does the M18 sensor need for mounting?

The sensor uses an M18 × 1 thread with a 33 mm thread length and an overall housing length of 50 mm.

How do you wire the 4-pin M12 connector on this NPN sensor and what supply voltage is required?

Connect the DC 3-wire NPN output to a 10 V DC to 30 V DC supply; the male M12 4-pin connector carries the switching signal and power.

What maintenance does the IP67 nickel-plated brass housing and PA 66 sensing face require over its operating temperature range?

The IP67-rated metal housing and plastic sensing face need no routine maintenance across –25 °C to +75 °C; replace the unit if the sensing face is damaged.
