FSS58I-F3AADR3GN-0013 Inox Gray Code and Radial Connector Mapping

For FSS58I-F3AADR3GN-0013, EncoderWorks can provide a custom compatible replacement focused on Inox housing protection, 13-bit Gray code mapping, radial 19-pin connector wiring, and Ø15 mm recessed hollow-shaft fit. This model should not be grouped with the aluminum axial-plug version. The real replacement risk is that the stainless-steel body may fit the environment, but the controller may still read the wrong absolute position if Gray code order, V/R logic, LATCH timing, or connector assignment changes.

The FSS58I-F3AADR3GN-0013 is a singleturn absolute encoder with fast parallel push-pull output, 13-bit resolution, Gray code, Inox stainless-steel housing, F3A Ø15 mm recessed hollow shaft, AD 19-pin connector, radial exit direction, and V/R, LATCH, PRESET inputs. The FSS58 series uses direct code-disc readout for rapid data transfer and supports code change frequency up to 400 kHz without relying on a microcontroller.

The first failure boundary is Gray code decoding. Gray code is useful because only one bit should change between adjacent positions, but the benefit disappears if the controller input expects binary data or the bit order is shifted. In replacement work, Data bit 1 through Data bit 13 must be mapped by signal function, not by cable color or connector location alone.

This replacement fails when all parallel outputs are switching, but the PLC decodes an incorrect shaft angle because the 13-bit Gray word is wired in the wrong order or interpreted as binary. The encoder looks electrically alive, yet the machine position is wrong.

The second boundary is the radial AD connector. The 19-pin connector carries the data bits, power, V/R, LATCH, and PRESET inputs. Radial exit direction can change cable bend radius, shield strain, and plug clearance inside a compact machine frame. A plug that is physically compatible may still fail if the control inputs are left floating or assigned to the wrong pins. The FSS58 connection table identifies the data outputs and the V/R, LATCH, and PRESET control inputs separately.

LATCH should be checked as part of the controller read cycle. When active, it freezes the parallel position word so the controller does not read during a data transition. PRESET must also be protected because it electronically sets the output word to zero. A wrong PRESET input can create a false machine zero without any encoder hardware fault.

The Inox housing is useful in corrosive, wet, washdown, or exposed industrial environments, but stainless steel does not correct mechanical preload. The Ø15 mm recessed hollow shaft must slide onto the shaft cleanly, and the torque rest must hold the housing without forcing alignment.

The replacement decision should first confirm Inox housing requirement, F3A Ø15 mm shaft fit, torque-rest freedom, radial AD connector clearance, 13-bit Gray code order, V/R counting direction, LATCH pulse timing, PRESET behavior, supply voltage, and controller input thresholds. EncoderWorks treats FSS58I-F3AADR3GN-0013 as an industrial encoder custom compatible solution where environmental housing choice, Gray code interpretation, and connector mapping must be verified together.

Typical production lead time: 15 working days.
