MA850 - 8-Bit Contactless Angle Encoder

General Description

The MA850 is an easy-to-use, magnetic, angle encoder with a digital output designed to replace analogic potentiometers or rotary switches.

The MA850 is designed for slow operation such as human-machine interface, manual controls, etc.

where the rotating speed remains below 200 rpm.

Key Features

  • programmable magnetic field strength thresholds, which allow for the implementation of a push or pull button function. These are output as two logic signals. On-chip non-volatile memory provides storage for configuration parameters, including the reference zero angle position and magnetic field detection threshold settings.

MagAlpha MA850 8-Bit Contactless Angle Encoder with PWM Output and Push Button Function DESCRIPTION The MA850 is an easy-to-use, magnetic, angle encoder with a digital output designed to replace analogic potentiometers or rotary switches. The MA850 is designed for slow operation such as human-machine interface, manual controls, etc. where the rotating speed remains below 200 rpm. The sensor detects the absolute angular position of a permanent magnet attached to a rotating shaft and outputs a PWM waveform with 8-bit resolution. The magnet shapes and configurations are very flexible. Typically, the MA850 is used with a diametrically magnetized cylinder of 2 - 8mm in diameter.
