Selection & installation notes
- The prose calls 22.5 mm the height, but the original drawing uses it as a length segment and shows 16 mm side-view height. The dimensions above follow the original drawing; confirm the production connector before machining.
- Matching color helps mechanical keying but does not verify polarity or voltage. Check both contacts and circuit labels before mating; never modify keying.
- Crimp contacts before inserting into housings, using the correct barrel, conductor and tool. Confirm retention and provide strain relief.
- Disconnect the load and isolate supply before mating or separating. This page does not establish a load-break or hot-plug rating.
- The 50 A class is not guaranteed for every wire size, temperature or bundling condition. Confirm current derating and protection coordination. Dust covers do not establish a waterproof rating.
