The TURCK BI4U-M12E-VN44X is an ultra-durable M12 inductive proximity sensor built for applications requiring a high degree of electrical resilience and compact installation. It offers a 4 mm sensing range in a flush-mount configuration and is housed in a corrosion-resistant stainless steel body suitable for tough industrial use. This sensor delivers a 3-wire NPN normally open output and supports an extended operating voltage of 10…60 VDC, making it compatible with a broad range of control systems. A 2-meter PVC cable provides flexible installation in confined or complex cable routing environments. With IP67 protection, it withstands moisture, dust, and vibration for reliable performance in harsh conditions. Key Features: • 4 mm flush sensing range for space-constrained detection • NPN output (Normally Open) – compatible with sinking input logic • Extended operating voltage: 10–60 VDC – supports a variety of systems • M12 cylindrical stainless steel housing – robust and corrosion-resistant • Cable connection (2 m) – flexible and easy wiring • High switching frequency for rapid detection tasks • IP67 ingress protection – dust-tight and waterproof • Ideal for packaging machines, conveyors, and process automation
