The IFM MGS205 is a full-metal magnetic sensor designed for robust position detection in demanding industrial environments. It provides a 70 mm sensing range with the M4.0 reference magnet. Unlike the PNP version in the same full-metal family, the MGS205 uses an NPN normally-open output. Its M18 × 1 stainless-steel housing and M12 connector provide a durable industrial installation format. IP65/IP67 protection, 5000 Hz switching and 200 mA output capability support reliable high-cycle operation.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
The MGS205 uses a GMR-based magnetic sensing principle for non-contact position detection. It provides a 70 mm sensing range when referenced to the M4.0 magnet. Its magnetic response sensitivity is 0.9 mT. The 1–10% hysteresis range supports stable switching behaviour. This allows reliable position detection even with mechanical tolerances.
The MGS205 uses an NPN normally-open electrical output. It operates from a 10–30 V DC supply with current consumption below 10 mA. The switching output supports up to 200 mA continuous current. Switching frequency reaches 5000 Hz. Short-circuit and overload protection are included for improved electrical reliability.
The sensor has an M18 × 1 full-metal stainless-steel housing. The sensing face is manufactured from stainless steel 316L/1.4404. Gold-plated M12 contacts provide a durable electrical connection. A yellow LED indicates the switching status. Two lock nuts are supplied for secure threaded installation.

The 70 mm sensing range provides installation flexibility around machine structures. Magnetic detection can operate through suitable non-magnetisable metal barriers. This allows the sensor to monitor moving components without direct physical contact. The stable switch point helps compensate for normal mechanical tolerances. These characteristics make the MGS205 suitable for robust machine-position monitoring.
The MGS205 uses stainless-steel construction for demanding industrial installations. It operates from -25 to 75 °C. IP65 and IP67 protection help protect against dust and water ingress. The sensor withstands high switching rates while maintaining a compact threaded form. Its full-metal construction also supports applications requiring increased resistance to impact, shock and vibration.
