Sensor type and voltage range

The Turck NI8U-G12-ADZ32X-B3131 is an inductive sensor built for electricians and maintenance engineers who need reliable metal detection. It operates on AC 2-wire 20…250 VAC or DC 2-wire 10…300 VDC supplies, fitting a wide range of industrial control circuits. The M12 × 1 threaded barrel allows direct mounting into standard tapped holes. A normally open contact switches when a target enters the sensing field.

Factor 1 and magnetic immunity

The uprox®+ design gives a factor 1 response for all metals, so the rated switching distance stays consistent whether the target is steel, aluminium, copper or brass. Chrome-plated brass housing and an IP68 protection class resist water ingress and harsh environments. Resistance to magnetic fields prevents false triggers near welding equipment or large motors. A 1/2" male connector provides a secure electrical connection without separate cable glands.

Suited for non-flush mounting

This unit suits non-flush installations where the sensor face sits proud of the surrounding metal, such as conveyor side-guides or robotic gripper jaws. The extended temperature range supports cold-store and high-ambient applications. Buyers who need a flush-mountable housing or a normally closed output should look at other models. The 35 g weight keeps added mass low on moving arms.

Questions about this item

Does the 1/2" male connector need periodic replacement?

The connector is part of the sealed IP68 housing and is not a user-serviceable item; no scheduled replacement is required.

What stops continuous operation first — temperature or switching frequency?

The extended temperature range and high switching frequency are both rated for continuous industrial use; neither limit is reached first under normal conditions.

How much heat does the sensor generate when running all day on 250 VAC?

Power dissipation is low; the chrome-plated brass barrel dissipates heat effectively, so the housing stays within the rated temperature range during continuous operation.
