Turck BI15-CK40-RDZ30X2-B3131 Inductive Proximity Sensor

The Turck BI15-CK40-RDZ30X2-B3131 S34 Inductive Proximity Sensor provides non-contact detection of metallic objects and precise machine-position sensing in harsh industrial environments, packaged in a compact CK40 Stubby housing. With a 15 mm sensing distance and normally closed (NC), 2-wire AC/DC output, it supports a wide supply window—20-250 VAC or 10-300 VDC—and can handle 3-400 mA of switching current, making it compatible with mixed-power automation systems. This shielded inductive sensor uses a 1/2" Microfast Male Connector (B3131), 3-pin connection, and features IP67 protection plus two LED indicators for status checks; it includes a BS 2.1 mounting bracket for quick installation. Common applications include end-of-travel monitoring, machine positioning, part presence verification, and product detection in PLC-controlled manufacturing environments, with weld-field immune performance (S34) well suited to robotic welding cells, automotive assembly lines, conveyors, and packaging equipment operating near electromagnetic interference.
