EM2 Transmissive Optical Encoder Module Page 1 of 7 Description The EM2 is a transmissive optical encoder module designed to offer 2x or 4x higher resolution than the EM1 encoder module.
This module is designed to detect rotary position when used with a US Digital� encoder disk.
The EM2 consists of a lensed LED source and a monolithic detector IC enclosed in a small polymer package that is identical to the EM1.
The EM2 uses phased array detector technology to provide superior performance and greater tolerances over traditional aperture mask type encoders.
The EM2 provides digital A & B quadrature outputs with a third output index channel.
Each EM2 module is resolution specific and is matc...
