Engineering details
The enclosure is published at IP65: dust-tight and protected against water jets from a 6.3 mm nozzle, with sealed connectors at the harness exit. It is not an immersion rating.
- IP65 enclosure with sealed connectors and vent membrane
- CAN communication on the harness pin-out — protocol confirmed per program
- Blown-fuse indication
- PCB-based circuit layout
Mechanical layout
Mating connectors
The standard NBX-961 build uses 4 sealed TYCO harness-side connectors from the 1670901 series. Wire-side seals, terminal P/N and pin-out are confirmed against the customer harness drawing at quotation.
| ID | Connector P/N | Brand |
|---|---|---|
| A | 2-1670901-1 | TYCO |
| B | 1-1670901-1 | TYCO |
| C | 4-1670901-1 | TYCO |
| D | 3-1670901-1 | TYCO |
Fuse & relay configuration
Standard build, customised on a programme basis:
| # | Component | Spec | Qty |
