Turck BI5-GT18ADZ30X2-B3331 Inductive Proximity Switch

The Turck BI5-GT18ADZ30X2-B3331 Inductive Proximity Switch delivers reliable 5 mm metal-target detection in harsh industrial environments, supported by magnetic-field immunity and a PTFE-coated housing that resists weld-field conditions. This 2-wire normally open sensor operates on 20-250 VAC or 10-300 VDC and carries up to 400 mA AC (300 mA DC) with a switching frequency of 20 Hz, making it suitable for high-speed automation tasks. Its flush-mount (embeddable) design fits tight installations, featuring a 1/2-inch male 3-pin connector, M18 x 1 threaded brass housing, and PTFE-coated brass body with a PBT, PTFE-coated active face, all rated IP67 and operable from -30°C to +85°C. The BI5-GT18 is used for metal object detection, machine positioning, conveyor sequencing, and part presence verification in welding fixtures, automotive body lines, robotics cells, and other environments with weld spatter and electrical noise, and it belongs to Turck's UPROX series with CE, IEC, and RoHS compliance. Common replacements include BI5U-G18-ADZ30X2-B3331, BI5U-G18-ADZ30X2-B1331, and NI12U-G18-ADZ30X2-B3331.
