M12 Inductive Sensor for Industrial Detection

The Turck BI3U-M12-AP6X 1634100 is a flush-mountable inductive sensor built for reliable metal detection in automation systems. Its threaded M12 × 1 brass barrel with chrome plating withstands harsh environments while providing a rated switching distance of 3 mm. The unit operates on 10…30 VDC with a PNP normally open output, making it suitable for standard DC control circuits. Factor 1 performance ensures consistent sensing across all metals without correction factors.

Cable Connection and IP68 Protection Simplify

A fixed cable connection removes the need for separate connectors, reducing potential failure points in high-vibration settings. The IP68 rating confirms protection against continuous immersion and dust ingress, supporting deployment in wet or contaminated areas. Resistance to magnetic fields prevents false triggers near welding equipment or large motors. Extended temperature tolerance and high switching frequency allow use in fast-cycling processes without thermal derating.

Suits Machine Builders Needing Compact.

This sensor fits applications where space is limited and exposure to coolant, oil, or magnetic interference is expected. Buyers requiring connectorised variants, analogue output, or larger sensing ranges should evaluate alternative models. The 101 g weight and metal housing support secure mounting in metal frames or brackets. Three-year parts and one-year labor coverage from the manufacturer back the hardware in fixed installations.

Questions about this item

Does the M12 × 1 threaded barrel or the chrome-plated brass housing need periodic replacement?

The sensor is built with a chrome-plated brass barrel and an IP68-rated cable connection; no user-serviceable parts are listed, so no scheduled barrel or housing replacement is required.

What limits continuous operation — the 10…30 VDC supply range or the high switching frequency?

The extended temperature range and high switching frequency are both supported by the uprox®+ design; neither the voltage window nor the switching speed is cited as a continuous-duty bottleneck.

How much heat or noise does the 101 g sensor produce when running all day on a 10…30 VDC line?

As a solid-state inductive sensor it has no moving parts and draws only milliamps, so audible noise is absent and heat rise is negligible during all-day operation.
