Optical encoder module
32 - 2500 cpr | EM1 US Digital

The EM1 is a transmissive optical encoder module designed to detect rotary or linear position when used together with a code wheel or linear strip. The EM1 consists of a lensed LED source and a monolithic detector IC enclosed in a small polymer package. The EM1 uses phased array detector technology to provide superior performance and greater tolerances over traditional aperture mask type encoders.

The EM1 provides digital A & B quadrature outputs with an optional third output index channel. Each EM1 module is resolution specific and is matched to the resolution of a code wheel or linear strip. The EM1 operates with a single 5V supply and provides single ended outputs which are capable of both sinking and sourcing 8mA. An internal 0.1 uF decoupling capacitor is designed into the EM1 to provide enhanced noise immunity.
