PRODUCT DESCRIPTION
FANUC A860-0392-V166 - Serial Absolute Encoder
This component is a FANUC Alpha i series serial absolute encoder, designated for high-precision position feedback within industrial servo motor systems. It delivers absolute position data via a proprietary FANUC Serial Encoder (FSSB) interface, eliminating the requirement for homing cycles during system initialization. This encoder is critical for closed-loop control in FANUC Alpha i series servo drives, primarily utilized in CNC machine tools, robotic manipulators, and advanced automation equipment.
