18 mm Inductive Sensor for Industrial Automation
This nickel-plated brass proximity sensor detects metal targets up to 8 mm away using inductive technology. It operates on 12 to 48 V DC with a 3-wire NPN normally-open output rated for 200 mA. The 41 mm long cylindrical body carries NEMA 4X, IP68 and IP69K ratings for harsh environments. It suits machine builders and maintenance engineers needing reliable presence detection on conveyors, presses or assembly lines.
Check Voltage, Wiring and Mounting Before Ordering
Verify your control system supplies 12 to 48 V DC and accepts a 3-wire NPN sinking signal with a normally-open logic state. Confirm the 2 m cable length reaches your terminal block or connector without splicing. The shielded 18 mm threaded barrel requires a matching mounting hole and clearance for the 41 mm overall length. Ensure the operating temperature range of -13 to 158 °F covers the application environment.
Replaces Worn 18 mm Shielded Sensors
This unit directly substitutes older 18 mm inductive sensors that lack IP68 or IP69K sealing or that have degraded sensing distance. The upgrade is worthwhile when equipment faces high-pressure wash-down, coolant immersion or vibration that damages lesser-rated housings. It is not for applications requiring longer sensing ranges, PNP sourcing outputs, AC supply voltages or non-metallic target detection.

Questions about this item
Does the sensor ship with a mounting bracket or must one be purchased separately?
The sensor body is nickel-plated brass, 18 mm diameter and 41 mm long with a 2 m cable; no bracket is included so a compatible mount must be sourced separately
Which output type suits a PLC input that expects a sinking signal?
The 3-wire NPN normally-open output pulls the signal low when metal is detected, matching a sinking PLC input
What does the 8 mm detecting distance mean when the sensor is flush-mounted in steel?
Shielded construction allows the full 8 mm range even when the barrel is fully embedded in metal, with a 1 000 Hz switching rate and 200 mA load limit
