HTA25 encoder - robust, compact shaft encoder with ball bearing

The HTA25 single-turn encoder is a robust encoder with magnetic sensor technology. This is due to the solid aluminum housing, the high IP protection class and a double ball-bearing stainless steel shaft that withstands high axle loads and allows high actuation speeds. The signal processing is digital and based on magnetic recording of measured values. The gradient-based evaluation ensures high interference immunity, e.g. against temperature fluctuations and EMC influences. This technology leaves the disadvantages of conventional Hall sensors far behind. HTA25 rotary encoders are designed for maximum service life and even surpass the robust optical data acquisition. The number of defects or failures in rotary encoders with this technological design is practically zero, even after decades of use.

Customer specific modifications such as shaft geometries, signal output functions, special cable lengths or individually assembled electrical connection cables are available.
