US Digital Adds 800 CPR Resolution to EM1 Module to Support 2-Phase Stepper Motors, Other Applications

Vancouver, Wash. — US Digital on Tuesday announced that it is adding 800 CPR resolution to its EM1 transmissive optical encoder.

The EM1 module is available in various CPRs ranging from 32 to 2500. The latest addition of 800 CPR makes the EM1 better suited for two-phase stepper motor applications, specifically for microstepping.

The new resolution will also be available on optical encoders that use the module including the E2 and E5 optical kit encoders.

The EM1 operates with a single 5V supply and provides digital A & B quadrature outputs with an optional third output index channel.
