Turck Ni30-K40SR-BZ3X Inductive Proximity Sensor

The TURCK NI30-K40SR-BZ3X Inductive Proximity Sensor delivers reliable non-contact metal detection with a 30 mm sensing distance for industrial automation that relies on AC-powered control circuits. This 2-wire AC switching output device operates on 20-250 VAC and is designed around inductive sensing in the rectangular K40 thermoplastic housing, with IP67 protection and a wide operating range of -25°C to +70°C. The unit supports either an integral cable or a terminal connection depending on configuration, and offers a rated output current of 5-500 mA with a switching frequency of approximately 20 Hz, making it suitable for end-of-travel sensing, machine sequencing, and position monitoring on conveyors, material handling lines, packaging equipment, and process machines. Features include short-circuit and overload protection, LED status indication, and wear-free operation, contributing to reliable performance in harsh factory environments. Common replacements to consider are TURCK NI20-K40SR-BZ3X, NI40-K40SR-BZ3X, and BI30-K40SR-VP44X.
