Meyle Absolute Rotary Encoder

The resolution of a two channel encoder can be multiplied by two or four using a special edge detecting. An encoder with physically 5000 pulses per revolution can generate 20000 pulses per revolution using this technique.

When used in environments, with a lot of electrical noise and/or if very long cable distances are required, we recommend to use encoders with inverted (complementary) signals. These signals are always available with output circuits of the RS 422 type and sine wave outputs. Meyle also offers them for push-pull outputs.

Incremental encoders simply count the number of pulses engraved on the disk and in case of power shut-down, it is necessary to find out the origin at every new start.
