HTx25K encoder - robust, compact 

The kit encoders of the HTx25K series are specially designed for applications in demanding environments with limited space, where the rotation or angular position of externally mounted components are measured. The rugged contactless encoders in the Ø25 mm metal housing can be precisely matched to the respective area of application thanks to their numerous electronic and mechanical options. Whether as incremental or absolute value encoders, they cover a wide range of applications and, depending on the output electronics, are used in plant engineering, special machinery, and automated guided vehicles (AGVs), for example.

The HTx25K is the smallest metal-housed kit encoder in the MEGATRON product range. They feature a solid aluminium housing, a high IP protection and can be precisely aligned with the magnet in the application. The signal processing is digital and based on latest Hall sensor technology that ensure reliable magnetic recording of measured values. The gradient-based evaluation ensures high interference immunity, e.g. against temperature fluctuations and EMC influences.

In addition to many standard options, the modular system of the HTx25K encoders enables optimal adaptation to the respective requirements of the application. In addition, the concept also allows timely customer-specific adjustments (even in small series) based on a clearly structured price model. Typical modifications are, for example, customer-specific shaft geometries, custom signal output functions, special cable lengths or individually assembled electrical connection cables.
