M Series Magnetostrictive Linear Displacement Sensors for Construction Machinery, Special Vehicles, and Railway Vehicles
Temposonics MH Series
This is a robust magnetostrictive linear displacement sensor designed to withstand harsh environments such as shock, vibration, and temperature, utilizing magnetostrictive technology.
This sensor is a compact, non-contact, high-reliability sensor specially developed through rigorous testing to fit within hydraulic and pneumatic cylinders. To accommodate various applications, it offers selectable interfaces such as analog, PWM, CANbus, CANopen, and J1939. It also supports SIL2 and performance level d, which will become essential in the future.

basic information
■A compact stainless steel displacement sensor designed for use built into hydraulic cylinders ■Ideal for vehicle clevis-type cylinders and cylinders with limited installation space ■The sensor head is housed in a robust stainless steel case containing a circuit board ■The sensor rod incorporates a detection element and magnetostrictive wire within a pressure-resistant stainless rod, fitting inside a ground piston rod ■The magnet is the only moving part, mounted at the bottom of the piston, moving non-contact along the sensor rod without wear; the magnetic field generated by this magnet acts on the internal magnetostrictive wire as it passes through the sensor rod to detect the magnet's position 【Features】 ● Non-contact ● High precision ● Redundancy (Two sensors in one housing) ● Ultra-compact, suitable for integration into hydraulic and pneumatic cylinders ● Built-in for automotive, railway, and marine cylinders ● Measures absolute position and movement speed ● Interfaces available include analog (voltage, current), PWM, CANbus, CANopen, J1939, etc. ● Operating temperature range: -40℃ to +105℃

Company information
Temposonics introduced a non-contact, high-precision, and cost-effective non-contact absolute sensor method using the magnetostrictive effect (Weidmann effect) for position measurement in the early 1970s, which had previously been dominated by incremental methods. As a leading company in magnetostrictive sensors, we are committed to improving accuracy as position sensors, engaging in research and development, and enhancing quality to meet the needs of the industry. Our sensors are increasingly being adopted not only as linear sensors to replace rotary encoders, linear encoders, and potentiometers but also in various industries such as hydraulics, pneumatics, water pressure, injection molding, welding, printing, textiles, construction machinery, wind power generation, metal processing, as well as disaster prevention sensors like landslide sensors and bridge sensors. Temposonics will continue to develop and strive day and night to serve as a leading company in industrial sensors.
