To determine position values, POSITAL's new MAGNETOCODE (MCD) encoder series uses an integrated Hall circuit, which samples the magnetic field of a permanent magnet fixed to a shaft. This singleturn sensor provides a maximum resolution of 12 Bits per revolution. At the same time, MCD encoders register up to 8,192 revolutions (13 Bit) – models with a higher capacity are available upon request. Current absolute position values are stored permanently, even without external power supply, and are provided instantly after activation, using an innovative, patented technology, which renders backup batteries obsolete.
The MCD encoder's internal component is a Wiegand wire with a coil wound around it. The Wiegand wire generates the energy required for registering revolutions from the rotary motion – neither continuous rotation nor a minimum number of revolutions are necessary. MCD encoders are available as solid and hollow shaft versions.
The encoder can transmit data in either one of two fashions. The first is the synchronous serial interface (SSI). Secondly, the encoder can be connected to a CANopen field bus, as it is now available to use this protocol. Incremental and analog outputs are currently being developed.
