The IFM MN501S is a magnetically coded safety sensor designed for dependable monitoring of machine guards, safety doors and protective devices. It provides an 8 mm sensing range with a defined actuator, two normally open potential-free outputs and 24 V DC operation. The 6 m cable configuration offers additional installation reach for industrial machinery, while the compact rectangular housing and robust protection support reliable use in demanding automation and safety applications.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
The MN501S uses coded magnetic detection to monitor the position of protective machine components. It is designed to switch when the supplied or defined actuator enters the appropriate sensing area. The 8 mm sensing range provides useful mounting tolerance for machine guarding applications. Its 6 m cable configuration is convenient for installations where the sensor is located farther from the control equipment. The sensor supports continuous industrial operation.
The MN501S provides two normally open potential-free outputs and an 8 mm sensing range. It operates from 24 V DC and uses protection class III. The 88 x 13.1 x 25 mm rectangular housing provides a compact but robust mounting solution. A switching frequency of 150 Hz and response time of 10 ms support fast position monitoring. The extended 6 m cable helps simplify machine wiring.
The sensor is designed for repeated safety monitoring of guards, doors and protective covers. Its coded magnetic operating principle helps ensure that the intended actuator is detected reliably. The industrial housing supports operation in automated production environments. IP67 protection provides resistance to dust and water ingress. The 6 m cable can reduce the need for additional extension wiring in larger machine installations.
