Turck M30 capacitive sensor for AC circuits

The Turck BC10-M30K-AZ3X is a flush-mount capacitive sensor with a 10 mm rated switching distance. It suits electricians and maintenance technicians who need non-contact detection of liquids, powders or solid materials in industrial environments. The AC two-wire output operates directly on 20…250 VAC supply without a separate DC power unit.

Two-wire AC limits and voltage range

The sensor switches a normally open contact in series with the load, so a small leakage current remains in the off state and the load must tolerate the full mains voltage drop. The 20…250 VAC window covers common control voltages but excludes low-voltage DC buses and supplies above 250 VAC. Cable connection is fixed, so cable length cannot be changed on site.

Chrome-plated brass barrel and fine adjustment

The M30 × 1.5 threaded barrel is machined from CuZn brass with a chrome-plated surface that resists coolant, oil and cleaning agents. A built-in potentiometer allows fine adjustment of the switching point after mounting. At 214 g the unit adds minimal mass to brackets or machine frames, and the metal housing provides mechanical protection in harsh areas.

Questions about this item

How do I pick the right sensing distance for my application?

The sensor offers a 10 mm rated switching distance with a fine‑adjustment potentiometer so you can tune the trigger point precisely for the material you are detecting.

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

It detects a standard target at up to 10 mm when mounted flush in an M30 × 1.5 threaded barrel, and the potentiometer lets you reduce that range if needed.

What does the 20…250 VAC supply range cap in practice?

The AC 2‑wire output switches directly on the mains‑level supply, so the sensor can drive loads up to 250 VAC without a separate amplifier.
