FANUC A660-2005-T505 Pulse Coder Cable 90 Deg Angled

Technical Details & Specifications

Specifications

Industrial Applications

• FANUC CNC machining centres (milling, turning) servo-axis feedback where the motor is mounted in confined spaces against walls or in recesses.
• FANUC Beta BM compact servo motors — maintenance documentation confirms T505 as the service cable for Beta BM pulse coder connections.
• FANUC robot arm axis drives where motor mounting restricts straight-connector access.
• CNC lathes and turning centres whose motor installation geometry requires a 90-degree cable exit.
• Preventively stocking a spare angled cable for legacy FANUC servo installations to avoid unplanned feedback-loss downtime.

Design Purpose

The pulse coder cable is the signal link that carries encoder feedback from the servo motor back to the amplifier and controller. Without it, the control loop loses position and speed data and the axis cannot run accurately. The T505's 90-degree elbow connector lets the cable exit sideways at the motor, so it can be seated and locked even when there is no axial clearance behind the encoder socket. The difference versus the straight T506 is purely connector orientation, not signal content — both carry the same FANUC pulse coder interface. The cable is built as a flexible, industrial-grade assembly for drag-chain and confined routing.

Common Failure Modes

• Broken or cracked motor-end elbow connector from repeated flexing or forced routing.
• Shield or signal interruption causing position feedback loss, alarm, or axis drift.
• Cable jacket wear, cuts, or degradation in the drag chain.
• Loose or oxidized connector at the encoder or amplifier end.

Specific FANUC alarm codes tied to this cable are not officially documented for this model. Please contact us with the alarm shown on your controller for accurate diagnosis.
