MH-Series MS Analog/Digital Magnetostrictive Linear Position Sensor
Brand: Temposonics an Amphenol CompanyTemposonics sensors can be used in versatile mobile machines without any restriction and replace contact-based linear sensors like potentiometers.
Highly dynamic systems are controlled safely by means of Temposonics sensors, thus enhancing the productivity, availability and quality of the working process of the machine.
Insensitive to vibration, shocks, dust and weathering influence and electro-magnetic disturbances.
Temposonics MH Series sensors are successfully used in front axle and articulated frame steering cylinders, hydraulic jacks and in steering systems for hydraulic units on agricultural and construction machinery.
