9 Pin 1T5 Data Extension Cable Brake Senors Julet Display Connector Waterproof

Waterproof Brake Sensor + 1T5 Data Cable (Juliet / 9-Pin Controller Plug)

Designed for pedal bicycles • Neat, plug-and-play wiring • Water-resistant connectors

Product Overview

• This listing includes a waterproof brake sensor cable with magnets plus a 1T5 data cable. The brake sensor is designed to mount neatly to a hydraulic or mechanical bicycle brake lever, allowing the system to cut motor power when braking (when connected and configured with a compatible controller).

⭐ Key Features

• ✔️ Brake cut-off sensor with magnet set (for hydraulic or mechanical levers)
  ✔️ Waterproof Juliet connectors for cleaner installs and improved weather resistance
  ✔️ 9-pin plug to controller (simple, tidy controller connection)
  ✔️ Add-on for 250W kits where brake sensors are not included as standard

🔌 1T5 Data Cable Functions

• The 1T5 harness provides connections for the following (model-dependent):
  ✔️ Headlight / light output
  ✔️ Brake sensor input(s)
  ✔️ Display connection
  ✔️ Throttle connection
  ✔️ Left / right control connection (where applicable)
  Note: Exact port usage can vary slightly between controller/display setups.

📦 What's Included

• ✔️ 1 × Waterproof brake sensor cable (Juliet type)
  ✔️ Magnets / mounting pieces (as shown)
  ✔️ 1 × 1T5 waterproof data cable / harness
  ✔️ 1 × 9-pin controller plug connection (on the harness)

🛠️ Installation Notes

• ✔️ Clean the brake lever area before fitting the sensor/magnet for best adhesion and alignment.
  ✔️ Position the magnet so it passes the sensor closely when the lever is released (and separates when braking).
  ✔️ Connect matching waterproof plugs carefully—align arrows/keys and do not force connectors.
  ✔️ If you’re unsure, a local bike mechanic can fit this quickly.

✅ Compatibility

• Compatible with many aftermarket e-bike controllers/displays that use waterproof Juliet-style connectors and a 9-pin controller harness connection. Designed as an optional add-on for our 250W conversion kits for riders who want brake cut-off sensors installed.

⚠️ Safety & Support

• ✔️ Brake sensors are a helpful safety feature, but always ensure your brakes are correctly adjusted and maintained.
  ✔️ For compatibility questions, message us with a photo of your controller/display plugs and we’ll help confirm fitment.
