M27500-20SB2T23 Shielded Tefzel Cable, 2 Core 20 AWG

M27500-20SB2T23 is a 2 core / 2 conductors 20 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 2 core 20 AWG shielded Tefzel cable is suited to two-wire shielded sensors, trigger wiring, speed sensors and low-current ECU wiring where a larger 20 AWG conductor is preferred.

Shielded M27500 cable is useful where the wiring carries low-current sensor or signal information and extra protection from electrical noise is required. The braid shield is separate from the insulated conductors 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.
