Leuze IS 204MP/4NC-1E5 Proximity Sensor

Built by Leuze, the IS 204MP/4NC-1E5 is a high-performance miniature proximity sensor designed with a rugged stainless steel housing and a durable plastic active surface. It features a slim 4 mm diameter and M5 thread size for embedded mounting into tight machine spaces where standard sensors would not fit. Its small footprint makes it ideal for compact automation systems that require non-contact object detection with minimal intrusion.

This model operates on a wide 10 to 30 V DC supply and supports normally closed PNP switching output, ensuring consistent response in high-vibration or high-speed environments. The sensing range of 1 mm to 3 mm is finely tuned for short-distance metal detection, while the maximum switching frequency of 5,000 Hz allows it to handle fast production lines without signal dropouts. Its IP67-rated protection provides full resistance to dust and water ingress, making it reliable even in harsh or washdown settings.

Combined with a secure cable connection and efficient response behavior, the IS 204MP/4NC-1E5 proximity sensor reflects Leuze’s dedication to smart sensing in compact industrial environments. Trusted by machine builders and maintenance engineers alike, this sensor offers excellent repeatability, longevity, and integration flexibility. For complete specifications, please refer to Leuze’s official datasheet or consult our application support team.

The Leuze IS 204MP/4NC-1E5 Proximity Sensor is ideally suited for precision automation tasks where space and accuracy are critical. In automated part feeding systems, it detects the presence of metal fasteners, pins, or components before indexing, helping reduce misfeeds or cycle errors. Its flush mounting design allows seamless integration into jigs, arms, and tool holders without interfering with motion paths.

In CNC machines and robotic end-effectors, this sensor monitors tool presence or material positioning to prevent operational faults. With a normally closed switching output, it provides a fail-safe signal behavior — which is especially useful in safety-critical detection zones. It also performs reliably in small packaging equipment, confirming gate positions or verifying that containers are correctly placed before sealing or labeling operations begin.

Thanks to its IP67 protection, this Leuze proximity sensor maintains stable operation even in high-humidity, oily, or dusty environments — making it a trusted component in automotive, food processing, and electronics manufacturing lines. The IS 204MP/4NC-1E5 is the preferred solution when engineers need compact size, high speed, and robust construction in one reliable sensor.
