1 Core - 22 AWG Shielded Tefzel Cable - Sold Per Metre

M27500-22SB1T23 is a 1 core / 1 conductor 22 AWG shielded Tefzel cable for motorsport wiring, ECU wiring, sensor wiring, data logging and custom harness builds. It uses M22759/32 style lightweight ETFE insulated conductors, a round tinned copper braid shield and a white cross-linked modified ETFE outer jacket.

Part Number Breakdown

What This Cable Is Used For

This 1 core 22 AWG shielded Tefzel cable is suited to single shielded sensor signal circuits, low-current analogue ECU inputs, speed/reference signals and noise-sensitive data logging inputs.

Shielded M27500 cable is useful where the wiring carries low-current sensor or signal information and extra protection from electrical noise is required. This is a 1 conductor shielded cable, so the braid shield is separate from the insulated conductor and must be terminated correctly for the wiring design.

Common Motorsport Wiring Uses

• Aftermarket ECU sensor wiring
• Low-current analogue and digital signal wiring
• Crank, cam, speed and position sensor circuits where shielding is required
• Pressure sensor, data logging and dash input wiring
• Motorsport harness branches requiring shielded conductors
• Engine bay and race car wiring where lightweight ETFE cable is preferred

Important Wiring Notes

• Confirm the ECU, sensor or device pinout before wiring.
• Do not use the braid shield as the normal sensor ground unless the wiring design specifically requires it.
• Terminate the shield correctly to avoid noise issues or ground loops.
• Use proper shield termination, strain relief and adhesive-lined heatshrink at harness ends.
• Choose the core count based on the circuit requirement, not just what is easiest to stock.
• For higher-current power circuits, choose wire size based on current draw, voltage drop, cable length and circuit protection.
