Turck BI20-R-32SR-UN6X Ring Inductive Proximity Sensor

Description:

The Turck BI20-R-32SR-UN6X ring inductive sensor is used in industrial part counting and object passage detection systems. Commonly installed in wire processing machines, fastener feeders, tube conveying equipment, stamping lines, and automated assembly systems where metal parts pass through the sensing aperture. Maintenance teams and system integrators use this part for replacement, retrofit, expansion, and production automation upgrades.

Applications:

The Turck BI20-R-32SR-UN6X is designed for non-contact detection of metallic objects passing through a sensing ring in industrial automation environments. It is commonly used in screw counting systems, wire and tube monitoring equipment, parts feeders, stamping presses, and automated handling systems requiring reliable detection of small moving metal components for PLC-controlled processes. Ring sensors are particularly useful where conventional barrel sensors cannot reliably detect fast-moving or irregularly positioned targets.
