Cylindrical M18 stainless steel inductive sensor with M12 connector, 65 mm long

Sick

Sick IMF18-08BNPVC0S M18 8mm NPN inductive sensor

SKU CH-8VMF-9QDE4

M18 inductive proximity sensor detects metal at 8 mm with NPN complementary output, IP68 and IP69K sealing, and stainless-steel housing rated from –40 °C to +100 °C

  • 8 mm flush sensing range for reliable detection
  • NPN complementary output simplifies wiring
  • IP68 and IP69K ratings withstand wash-down
  • Stainless steel V2A housing resists coolant lubricants
  • Operates from –40 °C to +100 °C

Industrial M18 Inductive Sensor

The Sick IMF18-08BNPVC0S is an M18 cylindrical inductive proximity sensor with an 8 mm sensing range and a 6.48 mm safe sensing range. It operates on 10 to 30 V DC supply voltage and provides a complementary NPN output through a 4-pin M12 male connector. The stainless steel V2A housing and LCP sensing face achieve IP68 and IP69K enclosure ratings for harsh environments.

Upgrade from smaller or unsealed sensors

Choose this model when replacing sensors with shorter reach or lower environmental protection. The 8 mm flush-mount range suits applications needing reliable metal detection through coolant lubricants. The 1,000 Hz switching frequency supports fast cycling machinery where slower sensors miss targets. The wide –40 °C to +100 °C operating range handles extremes that damage standard units.

Fits M18 threaded ports with 47 mm thread length

The sensor requires a standard M18 x 1 threaded mounting hole and a 4-wire DC supply capable of 200 mA continuous current. Its 65 mm overall housing length and 90 Nm maximum tightening torque suit robust metal frames. The M12 connector frees panel space compared to cable glands. Short-circuit, reverse polarity and power-up pulse protection reduce external circuitry needs.

Questions about this item

What thread size and clearance does the M18 housing need for flush mounting?

The sensor uses an M18 x 1 thread with a 47 mm thread length and requires a maximum tightening torque of 90 Nm for flush installation.

How do I wire the 4-pin M12 connector for the NPN complementary output?

Connect the DC 4-wire cable to a 10–30 V DC supply; the NPN complementary output switches up to 200 mA with a 2 V drop and includes short-circuit, reverse-polarity and power-up pulse protection.

Which parts degrade first in coolant-lubricant environments and when should I plan replacement?

The LCP sensing face and V2A stainless-steel housing resist coolant lubricants, but the IP68/IP69K seals and 10 mA current consumption should be inspected regularly; replace if hysteresis drifts beyond 20 % or the 1000 Hz switching frequency becomes unstable.
