The IFM MFS211 is a full-metal magnetic sensor designed for robust position detection in industrial and hygienic environments. It uses a PNP normally-open output and provides a 60 mm sensing range when used with the M4.0 magnet. The sensor operates from 10–30 V DC and can switch loads up to 200 mA. Its stainless-steel housing, M12 connection and IP65/IP67 protection support demanding installations. The MFS211 is also suitable for applications where full-metal construction and high switching frequency are required.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
The MFS211 detects magnetic fields for non-contact position monitoring. It provides a 60 mm sensing range when referenced to the specified M4.0 magnet. The 1.3 mT response sensitivity supports reliable magnetic switching. A hysteresis of 1–10% of the sensing range helps provide stable switching behaviour. This makes it suitable for position and movement detection in industrial equipment.
The sensor uses stainless-steel construction for both housing and sensing face. Its full-metal design improves mechanical robustness compared with conventional polymer-bodied sensors. The threaded M12 × 1 body supports straightforward mounting with the supplied lock nuts. Gold-plated M12 contacts provide a reliable electrical interface. This construction is suitable for demanding industrial and hygienic environments.
The MFS211 operates at 10–30 V DC with current consumption below 10 mA. Its PNP normally-open output can handle up to 200 mA continuously. The sensor supports switching frequencies up to 5000 Hz. Short-circuit and overload protection are included. These characteristics allow the sensor to be used for fast machine-position monitoring.

The MFS211 has a compact M12 × 1 threaded body with a total length of 60 mm. Stainless-steel construction provides resistance to mechanical wear and demanding environmental conditions. Two fixing nuts are supplied for secure installation. The sensing face is also manufactured from stainless steel. This allows the sensor to be installed where polymer housings may be less suitable.
With a 5000 Hz switching frequency, the MFS211 can monitor rapidly changing machine positions. Its PNP output provides direct compatibility with many industrial control inputs. Short-circuit and overload protection improve electrical robustness. The 1.3 mT response sensitivity provides a defined magnetic switching threshold. These features make it suitable for high-cycle automation equipment.
