Magnetic Rotary Encoders with Solid or Hollow Shaft Family HTx36
HTx36 encoder - robust, ball bearing, sealed, with solid or hollow shaft
Sectional Model HTx36 S - Solid Shaft
Sectional Model HTx36 H - Hollow Shaft
The encoders of the HTx36 series are specially designed for use between simple applications and heavy-duty
applications. The contactless encoders in the Ø36 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 systems, laboratory devices and medical devices, for example.
HTx36 rotary encoders are among the most robust encoders with magnetic sensor technology in the
MEGATRON product range. This is due to the solid aluminium 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. B. against temperature uctuations and EMC inuences achieved.
This technology leaves the disadvantages of conventional Hall sensors far behind. HTx36 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.
In addition to a large number of standard options, the modular system of the HTx36 encoders enables optimal
adaptation to the respective requirements of the application. In addition, the concept also allows timely customer-
specic adjustments (even in small series) on the basis of a clearly structured price model. Typical modications
are, for example, customer-specic shaft geometries, signal output functions, special cable lengths or individually
assembled electrical connection cables.
