Turck BI5-S18-AZ3X Inductive Proximity Sensor

Turck BI5-S18-AZ3X is a 2-wire AC/DC inductive proximity sensor in Turck's BI Series that enables non-contact metal target detection with a 5 mm sensing distance, making it suitable for part presence verification and machine positioning in industrial automation. It is commonly installed on conveyors, packaging lines, assembly cells, and material-handling equipment where reliable metal detection and position sensing are required. The flush-mount sensor features an M18 x 1 threaded barrel, chrome-plated brass housing, and an integral 2 m cable, compatible with both legacy and modern control systems thanks to its 2-wire design. Electrical specs include a 20-250 VAC / 10-300 VDC voltage rating, 400 mA AC max or 300 mA DC max current, output type normally open (NO), and a switching frequency of 20 Hz. The BI5-S18-AZ3X is IP67 protected and operates from -25°C to +70°C, with CE, IEC, and RoHS compliance. Common replacements include Turck BI5-M18-AZ3X, Turck BI5-G18-AZ3X, and Turck BI5U-M18-AP6X-H1141.
