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

Turck BI20-R-32SR-UN6X is a 32 mm ring inductive sensor designed for non-contact detection of metallic objects as they pass through a sensing ring in industrial automation. It supports part counting and object passage detection and is commonly installed in wire processing machines, fastener feeders, tube conveying equipment, stamping lines, and automated assembly systems. The sensor's ring diameter is 32 mm, and it provides an integral cable with an NPN output that is selectable as normally open or normally closed, operating from 10–30 VDC with a maximum switching current of 250 mA. The plastic housing is IP65-rated and supports panel or bracket mounting, with installation focused on aligning the ring opening with the product flow path. Notable features include static output behavior and a large sensing aperture. This Turck part (MPN BI20-R-32SR-UN6X) is compatible with feeders, conveyors, wire processing equipment, and assembly machinery for PLC-controlled processes, and is commonly used in screw counting systems, wire and tube monitoring equipment, parts feeders, stamping presses, and automated handling applications.
