Optical Incremental Rotary - ENC-A5SI with Index

The ENC-A5SI is a single-ended, transmissive optical encoder module designed to detect the rotary position with a code wheel. The ENC-A5SI requires a minimum shaft length of .445" and maximum length of .570", and can be attached to the end of any shaft size ranging from .079" to .394" in diameter to provide digital feedback information. This single-ended encoder consists of a LED source lens and a monolithic detector IC enclosed in a small polymer package. These modules implement phased array detector technology providing superior performance and tolerances over traditional aperture mask type encoders. The ENC-A5SI series provides digital quadrature squarewave outputs on all resolutions and are capable of sinking or sourcing 8 mA each. These encoders are powered from a single +5VDC power supply and are RoHS compliant and REACH certified.
