ZH8525 Bayonet Circular Connectors (26482 Series II Type)
26482 Series II type · bayonet · to +200 °C
K Series Hermetic Receptacles (26482 Type)
26482 type · shells 8–24 · 3 to 61 contacts
K series receptacles are hermetic versions of our 26482-type bayonet circular connectors, built to GJB 598A (the Chinese counterpart of MIL-DTL-26482). They mate with ZH8525 plugs of the same shell size and layout. K receptacles use wire-wrap contact tails; K-F receptacles use solder tails.
