Sick IM18-10BNS-NC1 inductive proximity sensor M18 NPN NO 10 mm IP68 IP69K
M18 inductive sensor detects metal at 10 mm with IP68 and IP69K sealing
- 10 mm sensing range for reliable detection
- IP68 and IP69K ratings withstand high-pressure washdown
- Stainless steel V4A housing resists corrosion in harsh environments
- NPN normally-open output suits standard DC control circuits
- 300 Hz switching frequency supports fast automation cycles
Industrial M18 Inductive Sensor
The Sick IM18-10BNS-NC1 is a cylindrical inductive proximity sensor with an M18 x 1 thread and a 10 mm sensing range. It delivers a flush-mounted, NPN normally-open output on a 4-pin M12 connector for 10 V DC to 30 V DC systems. The stainless steel V4A housing and sensing face meet IP68 and IP69K enclosure ratings for harsh wash-down environments.
Upgrade From Shorter Range Sensors
This unit replaces sensors with a standard sensing distance by providing triple the typical range at 10 mm, with a safe sensing range of 8.1 mm. The jump is worth it when detecting metal targets at greater distances reduces mechanical collisions or allows more flexible mounting positions. A 300 Hz switching frequency supports fast automation cycles.
Verify Voltage Wiring And Mounting Space
Confirm the control system uses a 3-wire DC supply between 10 V and 30 V and can accept an NPN NO signal with a 2 V drop at 200 mA continuous current. Ensure the 63.5 mm housing length and 42 mm thread length fit the available clearance, and that the 50 Nm maximum tightening torque suits the mounting bracket. Operating temperature spans –25 °C to +85 °C.

Questions about this item
What thread size and clearance hole does the M18 sensor need for flush mounting?
The sensor uses an M18 × 1 thread with an 18 mm diameter. Drill an 18 mm clearance hole and allow 42 mm of thread engagement. Maximum tightening torque is 50 Nm.
How do I wire the M12 4-pin connector for the NPN normally-open output, and what mistake should I avoid?
Use a DC 3-wire cable on the M12 4-pin plug: brown to 10–30 V DC, blue to 0 V, black to the load. Do not exceed 200 mA continuous current and observe the 2 V voltage drop.
What ongoing checks or replacements does the IP68/IP69K stainless-steel sensor require in a wash-down environment?
The V4A stainless housing and sensing face resist corrosion. Periodically verify the 10 mm sensing range and 300 Hz switching frequency; replace the unit if hysteresis drifts beyond 15 % or reproducibility exceeds 5 %.
