Flange-mounted magnetostrictive displacement sensors combine high precision with rugged installation. The flange locks the sensor to hydraulic cylinders, tanks, or machine frames, while the magnetostrictive waveguide measures linear position without contact wear. Popular models include FMDS-50, FMDS-100, FMDS-200, FMDS-500, FMDS-1000, and FMDS-2000. The number usually shows the stroke in millimeters. A full model code may be FMDS-500-F2-A-24: 500 mm stroke, F2 flange, analog output, and 24 VDC supply.

Main specifications cover stroke from 50 mm to 3000 mm, resolution to 0.001 mm, linearity +/-0.05% FS, repeatability +/-0.002% FS, and hysteresis below 0.005% FS. Output choices include 4-20 mA, 0-10 V, 0-5 V, RS485, SSI, CANopen, and PROFIBUS. Supply voltage is often 12-24 VDC with ripple under 1%. Operating temperature is -40 C to +85 C. Protection is IP65, IP67, or IP68. The rod uses 304/316 stainless steel. The flange can be carbon steel or stainless steel with nickel plating. Pressure resistance reaches 35 MPa for cylinder use.

Flange specifications: standard ISO or custom flange, bolt holes, thread M18x1.5, M20x1.5, or M22x1.5, and flange diameter 45-80 mm. Installation must align the magnet, keep a 2-5 mm gap, and avoid strong magnetic fields. Typical applications are injection molding machines, hydraulic presses, servo valves, wind turbines, and steel mills. When choosing a model, confirm stroke, output, flange size, thread, cable length, and environmental rating. Models vary by stroke and flange.
