The IFM MN500S is a magnetically coded safety sensor designed for monitoring movable machine guards. It uses a coded actuator so that ordinary magnets cannot easily trigger the safety sensor. The sensor provides two normally open potential-free contacts. Its 88 × 25 × 13 mm rectangular construction supports installation on safety doors and guards. The 8 mm sensing range provides reliable coded-actuator detection.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
The MN500S uses magnetically coded sensing to monitor protective doors and guards. The coded actuator provides enhanced resistance to simple manipulation. Two normally open potential-free contacts provide safety-related switching information. The sensor can be connected to a suitable safety evaluation unit. This makes it suitable for machine-guard monitoring.
The rectangular sensor measures approximately 88 × 25 × 13 mm. Its compact format allows mounting on safety doors and protective guards. The sensing system uses a defined coded actuator. The actuator and sensor are positioned according to the specified sensing range. This arrangement supports reliable guard-position detection.
Magnetically coded sensing provides a practical alternative to conventional mechanical safety switches. The sensor is designed for continuous industrial operation. Suitable evaluation units can be used to achieve high safety performance levels. The system supports machine access monitoring. This helps prevent operation when the monitored guard is in an unsafe state.
