Current harness + 8x2m Thermistors Orion

The Orion BMS current sensor harness with eight thermistors on two metre leads, supplied as one assembly. Current sensing and temperature sensing share a single connector on the BMS, so they come as one loom.
The Orion brings its current input and its temperature inputs out on the same port. Building that as two separate looms means two things terminating into one connector, done by hand, at the point where a mistake affects both the pack's current measurement and its thermal protection. This is that loom already made.
Two metre thermistor leads are what make it usable across a real pack. Short leads confine you to sensors clustered near the BMS, which is exactly where the heat is not. Two metres lets the sensors go where the temperature actually needs measuring: on the modules, at the coolant path, at the busbars.
Eight measurement points is the Orion's own temperature capacity. If you need more than eight, that is what the thermistor expansion module is for.
Key specifications
| Part | CWHCRTH8 |
|---|---|
| Type | Current sensor harness with thermistors |
| Thermistors | 8, each on a 2 m lead |
| Connector | Single BMS port, shared by current and temperature |
| Compatible with | Orion BMS |
| Weight | 0.14 kg |
Features
- Current sensing and eight temperature channels in one pre made loom
- Two metre thermistor leads, so sensors reach where the heat is
- Pre terminated at the BMS, so the connector that matters is already right
- Saves hand building the one loom where a mistake affects both current and thermal protection
Compatibility
For the Orion BMS. The current sensor itself is a separate part and is chosen by your pack's maximum current.
If you need more than eight temperature points, the thermistor expansion module takes it to twenty and is the better answer for a multi module pack.
Place the sensors deliberately. Eight readings spread across the pack tell you far more than eight readings clustered where the loom happened to reach.
In the box
- 1 x current sensor harness
- 8 x thermistors on 2 m leads
