Incremental encoders

Signal level

Benefits

Analog signals sin/cos with level 1 V_pp

The analog signal allows the digitization of the trace signals.
In order to obtain a fine resolution, the signals are interpolated in the higher-level controller.

RS422 differential signals (TTL)

The resolution can be quadrupled by means of edge evaluation.

HTL (High Voltage Transistor Logic)

Built-on encoders with an HTL interface are designed for applications with digital inputs with a 24 V level.
The resolution can be quadrupled by means of edge evaluation.
