The IFM MFH209 is a pressure-resistant position sensor designed for piston detection in hydraulic cylinders. Its full-metal stainless-steel housing withstands operating pressures up to 500 bar and pressure peaks up to 1000 bar. The sensor detects ferromagnetic metals with a sensing range of 1.8 mm. It provides a configurable PNP normally open/normally closed switching output with a switching frequency up to 1000 Hz. Its M12 × 1 threaded body, IP65/IP68/IP69K protection, and high shock resistance make it suitable for harsh hydraulic applications.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
The MFH209 is designed specifically for position detection on hydraulic cylinders. It detects ferromagnetic piston components through its magnetic sensing principle. The 1.8 mm sensing range enables detection of the piston position at the cylinder end position. Its flush-mountable construction allows direct installation into compatible hydraulic cylinders. This provides reliable position feedback without requiring external mechanical switches.
The full-metal housing is designed for demanding hydraulic environments. It supports an operating pressure of 500 bar and pressure peaks up to 1000 bar. The minimum burst pressure is specified at 2000 bar. The sensor is designed to withstand repeated hydraulic pressure cycles. This makes it suitable for mobile hydraulics, forming equipment, valves, and other high-pressure machinery.
The MFH209 uses a PNP output that can be configured as normally open or normally closed. The switching output supports a permanent current rating of 200 mA. Its switching frequency reaches 1000 Hz. Short-circuit and overload protection improve electrical reliability. IP65, IP68, and IP69K protection support operation in harsh industrial environments.

The MFH209 detects the position of a ferromagnetic piston or steel component inside the hydraulic cylinder. Its magnetic sensing principle allows the sensor to remain protected inside the cylinder body. The compact sensing range is suitable for detecting end positions. The PNP switching signal can be connected directly to an automation controller. This provides dependable position feedback in high-pressure environments.
The MFH209 is designed for flush mounting using its M12 × 1 threaded body. Install the supplied O-ring and supporting ring correctly before commissioning. The specified tightening torque must not be exceeded. Inspect the sensor and hydraulic connection during routine maintenance. Ensure that the application remains within the specified pressure, temperature, and electrical limits.
