The IFM MN201S is a magnetically coded safety sensor for monitoring movable guards and safety doors. It provides two normally open potential-free contacts and a 5 mm sensing range. The sensor uses a 36 × 13 × 26 mm rectangular housing. A 6 m PVC cable provides the electrical connection. IP67 and IP69K protection with protected cable routing support industrial safety installations.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
The MN201S detects the presence of its coded actuator without mechanical contact. The coded arrangement helps prevent simple bypassing using ordinary magnets. Two potential-free normally open contacts provide safety switching information. The sensor is intended for use with suitable safety evaluation equipment. This allows it to be integrated into machine-guard safety circuits.
The 36 × 13 × 26 mm housing is suitable for compact guard installations. Its rectangular form allows straightforward mounting on doors and machine frames. The 5 mm sensing range provides a defined actuator position. The sensor and coded actuator can be concealed behind suitable materials for increased tamper prevention. This makes the design useful for compact machine safeguarding.
The MN201S uses a 6 m PVC cable for connection to the safety circuit. The sensor provides two normally open potential-free outputs. A 150 Hz switching frequency supports repeated guard movements. IP67 and IP69K protection support industrial installations when cable routing is protected. This provides a durable safety-sensor solution.

The MN201S uses a coded magnetic actuator rather than a simple permanent magnet. This makes unauthorized actuation more difficult. The non-contact system also avoids mechanical wear. Two safety contacts provide redundant switching information. This supports reliable monitoring of movable guards.
The sensor is intended for use with appropriate safety evaluation equipment. In a correctly designed safety circuit, the system can achieve high safety performance. Its compact size allows installation on smaller guards. The long 6 m cable provides flexibility for control-panel routing. IP protection supports industrial installation.
