18 mm inductive proximity sensor
This 18 mm cylindrical inductive proximity sensor suits machine builders and maintenance engineers who need reliable metal detection on conveyors, presses or packaging lines. It operates on 12 to 24 V DC and provides a three-wire NPN normally-open output for direct PLC or relay input.
Check voltage and wiring before ordering
Verify that the control system supplies 12 to 24 V DC and accepts a 200 mA NPN sinking signal. The sensor comes with a fixed 2 m cable, so plan cable routing and strain relief accordingly. Ensure the 5 mm sensing range meets the application gap and that the 2 kHz switching frequency is sufficient for target speed.
Nickel-plated brass body with IP68 and IP69K sealing
The shielded nickel-plated brass housing withstands high-pressure washdown and temporary immersion, making it suitable for food-processing and outdoor environments. Operating temperature spans -13 to 158 degrees F. The 41 mm overall length fits standard M18 mounting holes, and the pre-wired cable eliminates separate connector assemblies.

Questions about this item
What comes in the box with the XS518B1NAL2 and do I need to buy a mounting bracket separately?
The sensor ships as a single unit with a 2 m pre-wired cable attached; mounting hardware is not included and must be sourced separately.
Should I choose the 18 mm shielded version or an unshielded alternative for flush mounting in metal?
The shielded 18 mm barrel allows flush mounting in metal without affecting the 5 mm sensing range, while an unshielded model would require a clear zone.
How does the 2,000 Hz operating frequency affect detection on a fast conveyor?
A 2,000 Hz switching rate means the output can change state up to two thousand times per second, so the sensor keeps pace with rapid target presentation.
