Brantz BR1 Speedo Cable Sensor – How It Works

The Brantz BR1 speedo cable sensor converts the rotation of your gearbox or speedo cable into a digital speed signal for your BR1 display. It’s simple, reliable, and perfect for rally, race, or track use.

How It Works

• The sensor counts the rotations of your gearbox output or speedo cable.
• Each rotation creates a pulse.
• Your BR1 display reads these pulses and calculates your speed in real time.

Think of it as counting wheel turns to measure how fast your car is moving.

Easy Installation

1. Locate the gearbox speedo output (where your mechanical cable used to connect).
2. Remove any existing cable.
3. Fit the Brantz sensor to the output stub—threaded or clamped depending on your setup.
4. Connect the sensor cable to your BR1 display (power, ground, and signal).
5. Secure the cable away from hot or moving parts.
6. Power on the BR1 and set the pulses per revolution (PPR) in the menu to match your gearbox.

Key Benefits

• Works on any car with a mechanical speedo output
• Accurate digital speed reading for rally, racing, or track use
• Compact, reliable, and easy to fit
• Keeps your BR1 fully operational without the old mechanical cable

Tips

• Ensure the sensor aligns with the cable stub—no twisting.
• Keep it clear of heat and moving components.
• Set the correct PPR for accurate speed readings.

The Brantz BR1 sensor is the easy way to turn your mechanical speedo signal into a fully digital display—fast, accurate, and race-ready.
