The IFM MFH200 is a pressure-resistant magnetic position sensor developed for hydraulic-cylinder applications. It detects ferromagnetic piston positions through a compact stainless-steel sensing arrangement. The sensor provides a 1.8 mm sensing distance and is rated for hydraulic pressures up to 500 bar. It operates from 10–36 V DC and provides a PNP normally-open output with up to 200 mA load current. Its IP65/IP68/IP69K protection makes it suitable for demanding mobile and industrial hydraulic equipment.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
The MFH200 is designed specifically for position monitoring on hydraulic cylinders. Its magnetic sensing principle allows detection of ferromagnetic piston movement without mechanical contact. The 1.8 mm sensing distance provides a defined switching point close to the cylinder structure. Its pressure-resistant construction allows installation in high-pressure hydraulic environments. This makes it suitable for mobile hydraulics, industrial presses and hydraulic actuators.
The sensor is rated for operating pressures up to 500 bar or 50 MPa. Its minimum burst pressure is specified at 2000 bar. The stainless-steel housing provides mechanical strength for hydraulic-cylinder installation. FKM sealing and PTFE support components help protect the sensing assembly. A specified tightening torque below 15 Nm supports secure installation.
The MFH200 operates from 10–36 V DC and uses a PNP normally-open output. Its switching output supports up to 200 mA and switching frequencies up to 1000 Hz. Short-circuit and overload protection are provided. The sensor also includes reverse-polarity protection. These features support reliable position feedback in automated hydraulic systems.

The MFH200 uses an M12 × 1 threaded body with a total length of approximately 93 mm. Its compact construction allows installation in hydraulic-cylinder environments with limited available space. The sensor uses an M12 A-coded connection for industrial wiring. A locknut supports secure positioning. The stainless-steel body is designed for mechanically demanding applications.
The MFH200 provides IP65, IP68 and IP69K protection for challenging operating conditions. Its operating temperature range extends from -25 to 120 °C. The sensor is therefore suitable for hydraulic machinery exposed to elevated temperatures and contamination. Its pressure-resistant construction adds another layer of protection against hydraulic-system stresses. This combination makes it appropriate for demanding mobile and industrial equipment.
