What it is
The Omron R88A-CRGA003CR-E is a 3 m encoder and resolver cable from the R88A-CRGA family, sold under the Encoders category and used to carry the feedback signal between a servo drive and its motor-mounted encoder or resolver on an automation panel.
Where this class of cable lands on the line
Encoder and resolver cables of this type sit between a servo amplifier and the feedback device on the motor, where the cable length dictates the encoder signal integrity budget and the bend radius the cable can survive inside the cable chain on a moving axis.
