IS 208MM/2NO-4N0: 50109661 - Leuze 4mm NPN NO Inductive Switch

Built for robust industrial use, the Leuze IS 208MM/2NO-4N0 Proximity Sensor delivers precise 4 mm sensing distance and operates within a 10–30 V DC voltage range. Its NPN output with normally open (NO) logic enables straightforward integration into control circuits requiring activation upon target detection. The unit’s non-embedded design with an M8 thread size simplifies installation on metal mounting surfaces without reducing the sensing range.

Durability is assured with a stainless steel housing and a rugged plastic sensing face, engineered to endure challenging factory conditions including oil, dust, and vibrations. The sensor is equipped with a 2-meter PVC cable for easy wiring in distributed I/O systems, while the IP67 rating guarantees complete protection against dust ingress and water spray. Its high switching frequency of 3,500 Hz ensures fast and repeatable detection of small components in motion — critical for packaging lines, robotic arms, or automotive assembly cells.

Trusted for its performance, reliability, and ease of integration, the IS 208MM/2NO-4N0 sensor is widely used in OEM machinery and retrofit projects. Designed by Leuze, a brand known for precision sensor solutions, this proximity sensor helps improve machine uptime and control accuracy in demanding industrial environments.

The Leuze IS 208MM/2NO-4N0 Proximity Sensor is commonly deployed in high-speed conveyor systems, compact robotic grippers, and CNC machinery where accurate presence detection of metallic parts is critical. Its compact size and non-flush mount design make it perfect for detecting parts on tight machine frames without signal loss or interference.

Maintenance engineers prefer this model for retrofitting older machines due to its easy installation and compatibility with standard control voltages. The 3,500 Hz switching speed allows for error-free detection of moving parts even in high-throughput systems. It’s especially beneficial in applications such as automated sorting, carton sealing lines, and indexing tables.

Whether used in precision assembly or high-speed packaging environments, the Leuze IS 208MM/2NO-4N0 Proximity Sensor delivers the responsiveness, durability, and accuracy required by modern industrial automation systems. Choosing this proximity sensor means upgrading your production line with confidence and long-term value.
