Linear type ABSOCODER Sensor VLS®

Description

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.
