Turck M18 Inductive Sensor 10mm Range

The Turck NI10-G18-RZ3X2-B3331 is a chrome-plated brass inductive sensor with an M18 × 1 threaded barrel designed for non-flush mounting. It suits automation engineers and maintenance technicians who need reliable metal detection in industrial environments. The unit weighs 85 g and carries order number 4330791.

AC DC Voltage Limits 20 to 300 Volts

This sensor operates on both AC and DC two-wire supplies across a wide range. The AC rating spans 20 to 250 VDC while the DC rating covers 10 to 300 VDC. Installers must ensure the supply stays within these bounds to avoid damage or erratic switching behaviour.

NC Contact 1/2 Inch Connector

The switching element is a normally closed contact that opens when metal enters the 10 mm sensing field. Connection is made through a 1/2 inch male connector. Buyers who require a normally open output or a different connector type should select another model.

Questions about this item

Should I choose the 10 mm or 18 mm version for my application?

The 10 mm figure is the rated switching distance; the 18 mm figure is the M18 × 1 thread size. Both belong to the same sensor, so you do not select between them.

What does the 10 mm switching distance mean once the sensor is installed in a machine?

It means the sensor will reliably detect a standard metal target when that target comes within 10 mm of the sensing face.

The sensor lists AC 20…250 V and DC 10…300 V — what does that voltage range cap in practice?

It caps the supply voltage you may apply; the sensor will operate anywhere from 20 V AC up to 250 V AC or from 10 V DC up to 300 V DC.
