Turck BI5-S18-AN7 Inductive Proximity Sensor

The Turck BI5-S18-AN7 inductive proximity sensor delivers reliable non-contact metal target detection with a 5 mm sensing distance for industrial automation. As part of Turck's BI Series, it features a 3‑wire NPN normally open output, a 10‑30 VDC supply, a maximum 200 mA rating, and is widely used for sensor replacement, machine repairs, automation retrofits, and production line upgrades. Its M18 x 1 threaded barrel allows flush-mount installation (embeddable) with an integral cable connection, and the reinforced plastic housing is IP67 rated. Operating temperature range is -25°C to +70°C, and it meets CE, IEC, and RoHS standards. In practice, it supports part presence verification, machine positioning, end-of-travel sensing, and conveyor sequencing in packaging lines, bottling stations, robotic assembly cells, palletizing workflows, and other metal-detection tasks on automated production lines. Common replacements include Turck BI5-S18-AP7, BI5-S18-AN6X, and BI5U-M18-AN6X-H1141.
