SAA7129AH/V1,518 Overview
This encoder is embedded inside a 44-QFP package.Packing the encoder in a Tape & Reel (TR) case is recommended to ensure that it is protected.I have mounted this motor encoder in the way of the Surface Mount axis.There are two types of Video Encoder types that can be identified.This motor encoder is motor encoder of the SAA7129 family and is based on that.When switching power supplies are used, the digital power of the 3V~3.6V component of the optical encoder is applied.It is possible to apply an analog supply voltage by using 3.15V~3.45V.There is a Surface Mount mount for it.It is equipped with 44 pins on the encoder in question.As a general rule, it is recommended to pack the encoder magnetic in the 44-PQFP (10x10) case.
