Turck BI5-S18-AD4X Inductive Proximity Sensor

The Turck BI5-S18-AD4X inductive proximity sensor provides reliable non-contact detection of metal targets in industrial automation. It is used for part presence verification, machine positioning, end-of-travel sensing, and conveyor sequencing across packaging lines, bottling equipment, robotic assembly cells, palletizing systems, and other production machinery that require dependable switching in harsh environments. The sensor features a 5 mm sensing distance, 2-wire DC Normally Open output, and operates from 10 to 65 VDC with a maximum current of 100 mA and a switching frequency of 1000 Hz. Its flush-mount, embeddable design sits in an M18 x 1 threaded barrel with a chrome-plated brass housing and reinforced plastic sensing face, and it carries IP67 protection for dust and water ingress resistance in industrial settings. Connection options vary by variant, including cable connection or M12 connectors. The BI5-S18-AD4X is CE, IEC, and RoHS compliant, and is commonly cited with Turck replacement part BI5-S18-AD4X-H1141, BI5-M18-AD4X-H1141, and BI7-M18-AD4X-H1141.
