The Mitsubishi Electric OSA166ET2NA is an absolute rotary encoder used as the feedback device on Mitsubishi AC servo motors within CNC machine tool and industrial automation systems. Identified on the rating plate as ABSOLUTE ENCODER OSA166ET2NA, with serial number J5AW06SX10D and date code 1810, this unit is manufactured by Mitsubishi Electric Corp. in Japan and belongs to the OSA166 family of high resolution serial absolute encoders. Encoders in this family are factory mounted to Mitsubishi servo motors such as the HC SFS, HC RFS, and related platforms, providing position and velocity feedback to compatible Mitsubishi MR J2, MR J2S, and MR J3 series servo amplifiers and drives. The unit features a sealed metal housing with a circular mounting flange, an integral connector interface on the rear of the body for the encoder cable, and Mitsubishi Electric branding cast into the cover. The OSA166 series provides high resolution position feedback per revolution with absolute position retention, used by the servo drive system for closed loop motion control. Typical applications include CNC machining centers, CNC lathes, industrial robots, injection molding machines, and other servo driven motion control equipment where precise positioning and absolute home position recovery are required. Buyers replacing a failed OSA166ET2NA encoder, sourcing a spare for a maintenance program, or supporting a legacy Mitsubishi servo platform will recognize the part number from the original nameplate. Mechanical mounting and electrical interface are specific to the Mitsubishi OSA platform.
