ATM90-AUM12x12 SSI Cable Output and 1/2-Inch Through Hollow Shaft

For ATM90-AUM12x12, EncoderWorks can provide a custom compatible replacement focused on SSI cable-output mapping, 12-bit x 12-bit position agreement, and 1/2-inch through hollow-shaft fit. This model should not be treated as a blind hollow-shaft encoder. The shaft passes through the bore, so replacement risk is centered on through-shaft alignment, cable shielding, SSI timing, and whether the controller reads the same programmed absolute position.

The ATM90-AUM12x12 is a multiturn absolute encoder configuration with SSI interface, programmable 12-bit singleturn and 12-bit multiturn resolution, through hollow shaft, 1/2-inch shaft diameter, radial 12-core cable connection, and 5 m cable length. The platform uses magnetic singleturn scanning and mechanical multiturn gearing without battery operation. It is designed for robust industrial position feedback with IP65 housing protection and programmable resolution behavior.

The first failure boundary is SSI cable mapping. A 12-core radial cable must be checked by signal function, not only by color. Clock, data, power, ground, shield, zero setting, preset, and direction-related functions must match the original machine. If the cable is extended or replaced through a junction box, shield continuity and differential signal routing become critical.

This replacement fails when SSI communication is active, but the controller reads the wrong position because cable assignment, SSI timing, programmed resolution, zero/preset setting, or direction logic does not match the original encoder. The encoder may be functional while the receiving system interprets a different absolute value.

The second boundary is the through hollow shaft. This is not a blind bore. The application shaft passes through the encoder, so bore diameter, shaft runout, axial movement, clamping force, and mounting depth must be checked as a complete mechanical system. A through-shaft encoder can be damaged or produce unstable feedback if the shaft is eccentric, oversized, poorly supported, or loaded by cable strain.

Programming also matters. The model should be matched to the machine’s expected 12-bit x 12-bit scaling, zero reference, preset behavior, and counting direction. A replacement with the same interface and shaft can still be wrong if the controller expects a different resolution or preset state.

The replacement decision should first confirm SSI interface compatibility, 12-bit singleturn and 12-bit multiturn resolution, 1/2-inch through hollow-shaft fit, radial 12-core 5 m cable routing, IP65 requirement, zero/preset behavior, direction logic, programmed resolution, supply voltage, shielding, shaft runout, clamping condition, and mechanical load. EncoderWorks treats ATM90-AUM12x12 as an industrial encoder custom compatible solution where SSI cable integrity and through hollow-shaft mechanics decide field reliability.

Typical production lead time: 15 working days.
