HTx25 encoders - robust and compact with ball bearings

The HTx25 encoders are designed for use in demanding environments where space is at a premium. Housed in a Ø25mm metal body, these contactless encoders offer a wide range of electronic and mechanical options to suit the application. Whether as incremental or absolute encoders, they cover a wide range of applications and, depending on the output electronics, are used in systems, laboratory equipment and medical devices, for example.

The HTx25 is the smallest metal encoder with shaft in the MEGATRON HTx-Family. It has a solid aluminium housing, high IP protection and a stainless steel shaft supported by two ball bearings, allowing high actuation speeds. Signal processing is digital and based on the latest Hall sensor technology, which ensures reliable magnetic recording of the measured values. The gradient based evaluation ensures high immunity to temperature variations and EMC influences. The encoders are designed for maximum life and outperform even optical data acquisition.

In addition to a wide range of standard options, the modular design of the HTx25 encoders allows them to be tailored to the specific requirements of the application. The concept also allows for timely customization (even in small batches) based on a clearly structured pricing model. Typical modifications include customer-specific shaft geometries, customized signal output functions, special cable lengths or customized electrical connection cables.
