J599 Series III Circular Connectors (38999 Series III Type)
38999 Series III type · shell sizes 9–25 · 184 insert arrangements

Bulkhead feed-through · contacts up to 200 A · PR-C to +150 °C
P-C receptacles pass electrical circuits through a sealed bulkhead, with a P-type plug on each side. Contacts from Ø 1.5 mm (10 A) to Ø 9.0 mm (200 A) carry signal and power in the same shell. The heat-resistant PR-C version runs to +150 °C.
