GXP2W.B4011A2 SSI Axial Cable and Synchro Flange

For GXP2W.B4011A2, EncoderWorks can provide a custom compatible replacement focused on SSI axial cable pairing, Ø6 mm IP65 synchro-flange alignment, and programmed 13/12-bit position behavior. This model should not be treated as the same replacement case as the radial cable version. The cable exit direction changes rear clearance and strain control, while the SSI interface still depends on correct Clock+/Clock-, Data+/Data-, preset, and UP/DOWN handling.

The GXP2W.B4011A2 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, Ø6 mm synchro flange, IP65 shaft-seal execution, and 1 m axial cable connection.

The first failure boundary is SSI cable integrity. Clock+/Clock- and Data+/Data- must remain paired from the encoder to the receiver. If the cable is extended through a terminal strip or cabinet junction without preserving differential pair routing and shield continuity, the controller may receive intermittent data or shifted position words, especially at higher SSI clock rates.

This replacement fails when SSI communication is active, but the PLC reads unstable multiturn values because 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 is no longer reliable.

The second boundary is programmed data 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 code format, UP/DOWN direction state, or preset reference.

Mechanically, the Ø6 mm synchro flange is sensitive to coupling eccentricity and flange centering. The shaft should not absorb radial or angular misalignment. IP65 protection improves sealing, but it does not correct axial cable pull, coupling preload, or rear clearance problems.

The replacement decision should first confirm Ø6 mm synchro-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.B4011A2 as an industrial encoder custom compatible solution where SSI axial cable integrity and synchro-flange mechanics decide field reliability.

Typical production lead time: 15 working days.
