Connector selection determines IP rating. Unsealed connectors are restricted to cabin. Sealed (IP67/69K) require silicone seals.
9. Connector Pin Derating
Multiplying current by the number of adjacent loaded pins drastically increases local temp.

Common Mistakes in Connector Selection
- Assuming static theoretical values over empirical testing.
- Ignoring thermal derating curves in enclosed routing spaces.
- Applying generic global standards without cross-referencing European ISO 6722 limits.
Frequently Asked Questions
What is the primary standard for this?
Typically governed by IPC/WHMA-A-620 for manufacturing and ISO 6722 for the physical wire attributes.
How frequently should tools be calibrated?
At least every 50,000 cycles, or per shift for high-volume automated lines.
