Overview

The DSD25 series are three and four channel hall effect speed sensors for railway applications.
rail speed sensor

There are two major trends driving the increased demand on train speed sensors. First, the reduction of costs and weight of rolling stock, and second, the upgrade of train control systems to allow increased train density in saturated lines. Multi-channel Hall speed sensors address these challenges without the addition of weight and costs related to additional sensors. One sensor with two galvanically separated output stages provides reduced weight, less installation time and greater value.
