Heavy Duty Linear type ABSOCODER Sensor VLS®


Heavy Duty Linear type ABSOCODER Sensor VLS®

NSD linear absolute position sensor VLS ABSOCODER is an electro-mechanical sensor that measures the linear travel length and amount under magnetic reluctance change. ABSOCODER's outstanding durability with field proven performance is achieved by a creative construction of the design which eliminates mechanical contact parts and satisfies zero-electronics inside sensor. True heavy duty VLS series has been proven its excellent performance and durability especially to focus on AGC/AWC application under high vibration, high temperature, and water vapor environment.
