Built for high reliability and accuracy, the Leuze IS 205MM/4NC-1E5 proximity sensor combines a miniature design with industrial-grade durability. It features a slim 5 mm diameter and M5 thread for seamless embedded installation into compact fixtures and machine components. Operating on a flexible 10 to 30 V DC supply, this model supports a PNP output with a normally closed (NC) switching function, which is especially useful in fail-safe systems where loss of power or cable cut must be detected.
The IS 205MM/4NC-1E5 offers a precise sensing range of 1 mm to 3 mm, making it well-suited for detecting the presence of small ferromagnetic objects with minimal delay. Its impressive 5,000 Hz switching frequency enables rapid detection even in fast-moving processes. The sensor is enclosed in a stainless steel housing with a plastic active surface, designed to withstand vibration, dust, and moisture. Its IP67 protection rating ensures dependable performance in oily, dusty, or humid production zones, making it an excellent fit for food packaging, automotive lines, and precision tooling.
With a pre-mounted cable connection for straightforward integration, the Leuze IS 205MM/4NC-1E5 Proximity Sensor is trusted by engineers and OEMs who demand accuracy and longevity from their sensors. Backed by Leuze’s commitment to German engineering excellence, this sensor offers exceptional value for applications that require reliability in the smallest form factor.
