The TURCK BI5U-M18M-VN4X is a robust inductive proximity sensor engineered for reliable detection of metal targets in industrial environments. Featuring an M18 nickel-plated brass housing and flush mounting capability, it provides a 5 mm sensing distance ideal for space-constrained and embedded sensing applications. This model supports universal wiring (U-Type), allowing flexible installation and compatibility with a variety of control systems. It delivers a 3-wire NPN output with normally open (NO) logic, operating on 10…30 VDC. With its high IP67 ingress protection rating, the sensor ensures dependable operation in harsh conditions such as packaging lines, conveyors, and factory automation setups. Key Features: • Flush-mount design with 5 mm sensing range • M18 cylindrical housing – nickel-plated brass for durability • 3-wire NPN output (Normally Open) – standard for sinking input control systems • Universal wiring concept (U-Type) – simplifies inventory and installation • Supply voltage: 10…30 VDC • IP67 rated – resists water, dust, and oil • Suitable for robotics, conveyor systems, and general-purpose automation
