GXP2W.A4011A2 SSI Axial Cable and Clamping Flange

Replacing GXP2W.A4011A2 through EncoderWorks requires a custom compatible replacement check around SSI axial cable mapping, 13/12-bit programmed position behavior, and Ø10 mm IP65 clamping-flange alignment. This model should not be treated as the same case as the radial cable version. The electrical interface is similar, but axial cable exit changes bend clearance, shield routing, conductor strain, and how the cable enters the cabinet.

The GXP2W.A4011A2 is an SSI multiturn absolute encoder with optical sensing, 13-bit singleturn resolution, 12-bit multiturn range, 8192 steps per turn, 4096 turns, 10–30 VDC supply, SSI RS485 data output, RS232 programming interface, Ø58 mm housing, Ø10 mm clamping flange, IP65 shaft-seal execution, and 1 m axial cable connection.

The first failure boundary is SSI cable mapping. Data+/Data- and Clock+/Clock- must remain paired correctly from the encoder to the receiver. If the cable is extended through a terminal strip or replacement junction box without preserving differential pairing and shielding, the SSI word may become unstable. Axial cable exit also makes rear clearance important because cable stress can disturb sealing or pull on the housing.

This replacement fails when SSI communication is present, but the PLC reads intermittent, shifted, or incorrect multiturn values because the axial cable pair assignment, shield grounding, or SSI clock timing does not match the original installation. The encoder can be functional while the signal chain fails.

The second boundary is programmed position behavior. Total resolution, Gray or binary code, rotating direction, preset, offset, and zero point must match the previous encoder. A clean SSI word can still be wrong if the replacement uses a different programmed code or UP/DOWN direction state.

Preset handling should be controlled before startup. A preset pulse changes the electrical zero point, and UP/DOWN changes the counting direction. If either input is left undefined or wired differently, the machine can show a stable but incorrect position value.

Mechanically, the Ø10 mm clamping flange requires clean coupling alignment. The coupling should not transfer radial or axial preload into the shaft. IP65 protection improves sealing, but it does not correct flange distortion, coupling eccentricity, or cable strain.

The replacement decision should first confirm Ø10 mm clamping-flange geometry, IP65 shaft-seal requirement, 1 m axial cable assignment, SSI Clock+/Clock- and Data+/Data- pairing, 13-bit singleturn and 12-bit multiturn mapping, Gray/binary setting, UP/DOWN direction, preset behavior, RS232 programmed parameters, supply voltage, shielding, rear cable clearance, and coupling load. EncoderWorks treats GXP2W.A4011A2 as an industrial encoder custom compatible solution where SSI axial cable integrity and clamping-flange mechanics decide field reliability.

Typical production lead time: 15 working days.
