CD40257BEE4 Overview
There is an embedded encoder in the PDIP-16 package that contains the encoder.If you are packing the encoder in a Tube case, it is recommended that you do so.Through Hole directs this motor encoder to be mounted.It can be categorized as Data Selector/Multiplexer type.Total pins on the rotary encoders are 16.It is recommended that 3 V exceeds the minimum voltage required for the supply.As soon as the maximum supply voltage (Vsup) of a encoder motor reaches 18 V, the encoder motor is considered to be in operation.The converter operates with a voltage of 3 V to 18 V as the supply voltage for it.The total number of bits on an encoder is 2, which is the number of bits on the chip.In order to protect the encoder magnetic, it is recommended that it be packed in a 16-PDIP case.The quadrature encode belongs to the CD40257B series of electrical quadrature encodes.A encoder definition has Quad.
