IS 208MM/2NC-1E5: 50113207 - Leuze 1.5mm NPN Cylindrical Switch

The Leuze IS 208MM/2NC-1E5 is an 8 mm diameter cylindrical proximity sensor with an embedded M8 thread design, engineered for stable installation and consistent signal integrity. It features a sensing range of 1.5 mm and operates on a supply voltage of 10–30 V DC, making it compatible with a wide range of control systems. The sensor supports an NPN output with a normally closed (NC) switching principle, making it ideal for fail-safe detection applications where contact is required when the object is absent.

This model uses a durable PVC cable (2-meter length) for easy wiring and is rated for up to 5,000 Hz switching frequency, enabling fast response times in high-speed automation lines. The IP67-rated stainless steel housing provides robust protection against dust and water ingress, ensuring longevity in harsh industrial conditions. With a plastic active surface and compact cylindrical form factor, the Leuze IS 208MM/2NC-1E5 proximity sensor delivers dependable performance in precision automation tasks.

Its construction reflects Leuze's commitment to quality — from the corrosion-resistant body to the noise-immune output signal. This model meets global automation standards and supports seamless integration with PLCs, controllers, and signal processors.

The Leuze IS 208MM/2NC-1E5 proximity sensor is ideal for short-range presence detection in metal object positioning, cylinder piston monitoring, and part-detection applications on conveyors. Because of its 1.5 mm sensing distance and high switching frequency, it is commonly used in bottle-filling lines, stamping machines, and high-speed pick-and-place robotic arms.

Maintenance engineers will appreciate its simplicity — install it flush with your machine’s surface, connect the 2-meter PVC cable to the controller, and it’s ready to operate. No complex configuration is needed. The NC configuration also acts as a safeguard — ensuring the signal drops if the sensor fails or is disconnected, increasing operational safety.

In real-world applications, such as packaging lines or automatic tool changers, where dust or water may be present, its IP67-rated stainless steel housing ensures uninterrupted operation. With reliable detection and compact build, the Leuze proximity sensor becomes a trusted component in many factory automation systems.
