Turck BI4-G12-RDZ32X-B3131 Inductive Proximity Sensor

The Turck BI4-G12-RDZ32X-B3131 inductive proximity sensor provides reliable, non-contact detection of metallic targets in industrial automation with AC/DC universal operation and a 4 mm sensing distance. Designed for flush-mount installation in conveyors, packaging lines, assembly stations, and material-handling systems, it uses a 2-wire normally closed output and supports 20-250 VAC or 10-300 VDC supply, drawing 3-100 mA with a switching frequency of 20 Hz. The rugged chrome-plated brass housing (CuZn) features an M12 x 1 threaded barrel, a 1/2" 3-pin male connector, and PA12-GF30 active-face plastic, with IP67 protection and an operating temperature range from -25°C to +70°C. Key protective features include reverse polarity protection, short-circuit protection, and latching overload protection, making it suitable for PLC-controlled systems and applications in packaging equipment, conveyors, machine tools, and automated production lines requiring reliable position sensing and metal object detection.
