The IFM MN203S is a compact magnetically coded safety sensor with a 5 mm sensing range. It provides two normally open potential-free safety contacts. The sensor uses a 0.1 m PVC cable and a 4-pin M12 connector. Its 36 × 13 × 26 mm PA housing is designed for non-flush installation. IP67 and IP69K protection support demanding machine-safety applications.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
The MN203S detects a defined coded actuator without mechanical contact. Its 5 mm sensing range provides a controlled guard-position detection zone. Two normally open potential-free contacts support safety-circuit integration. The coded actuator reduces the possibility of simple magnetic bypassing. This makes the model suitable for machine access monitoring.
The sensor measures 36 × 13 × 26 mm. Its rectangular housing allows installation on machine guards and doors. The sensor is non-flush mountable. The 0.1 m cable with M12 connector simplifies connection to suitable safety wiring. This provides a compact and serviceable installation arrangement.
The MN203S is rated IP67 and IP69K when the cable is properly protected. It withstands 30 g shock and 10 g vibration within its specified test conditions. The operating environment supports temperatures from -25...80 °C. The PA housing provides a lightweight safety-sensor construction. These features support industrial guard-monitoring applications.
