The Leuze IS 208MM/4NC-1E5 Proximity Sensor features an M8 diameter housing with an embedded mounting type, allowing for tight integration in control panels and automation systems. Designed with a 1.5 mm sensing range and operating on a 10–30 V DC supply voltage, this sensor is optimized for precision tasks such as positioning and metal detection on assembly lines. The PNP switching output with a normally closed (NC) configuration ensures fail-safe performance in many critical systems. With a rapid 5,000 Hz switching frequency, it’s well-suited for high-speed applications like conveyor monitoring or robotic end-effectors.
Constructed using a durable stainless steel housing and sealed to IP67 protection class, the sensor resists dust, oil, and moisture—ideal for rugged environments. The active surface is made of plastic, which protects the internal sensing components. It includes a 2-meter PVC cable for easy integration, and its compact dimensions support installations where space is limited. All of this makes the IS 208MM/4NC-1E5 a trusted choice for industries like packaging, automotive, food processing, and electronic assembly, where consistent detection and reliability are essential for safety and system uptime.
The Leuze IS 208MM/4NC-1E5 Proximity Sensor is widely used in industrial automation for metal object detection within a 1.5 mm sensing distance. Maintenance engineers often prefer this sensor for tasks like end-position detection of pneumatic cylinders, gear tracking, or object presence verification on fast-moving belts. Its high switching frequency and small form factor make it perfect for compact machinery where detection reliability directly impacts productivity.
Thanks to its IP67-rated stainless steel body and sealed construction, it performs reliably in harsh environments such as CNC machines, pressing lines, and material handling systems. Even in high-vibration zones or oily surroundings, the sensor continues to deliver consistent outputs. Engineering teams also appreciate the pre-wired PVC cable, which simplifies wiring and reduces installation time.
Whether used in automotive welding lines, bottling plants, or electronic PCB inspection systems, the Leuze IS 208MM/4NC-1E5 Proximity Sensor ensures safe and uninterrupted machine operation. It’s built not just to detect, but to protect the performance of your industrial processes. This proximity sensor is a reliable partner in achieving automation precision.
