How to Choose the Right TPU Spiral Cable

Extended vs retracted lengthSpecify both the relaxed (retracted) length and the maximum extended length for your application range.

Conductor countCount all circuits including power, data, ground, and shield. Include in RFQ or wiring diagram.

Coil outer diameterHeavier gauge conductors increase outer coil diameter. Confirm space constraints with your mechanical designer.

End connector typeSpecify connector on each end: open wires, aviation plug, IP-rated circular, or custom type with pin assignment.
