8STA Circular Miniature Connector is a rugged aluminium product which provides optimum space and weight saving, whilst achieving maximum strength. It is available in either size 22 or 26 gold plated crimp contact or PCB contact. This connector has environmental sealing from interfacial seal and rear grommet. It also features a positive locking mechanism with locked colour indicators and 6 colours coded keyway orientations. Additionally, it has boot termination feature.
The 8STA circular miniature connector size 04 is a rugged aluminium‑body connector designed for harsh environments. It offers space‑saving design, optional gold‑plated crimp or PCB contacts, a positive locking mechanism with colour‑coded indicators, and a conductive black zinc plating.
The datasheet provides detailed mechanical characteristics (aluminium alloy shell, thermoplastic insulator), electrical ratings (up to 1000 Vrms test voltage, 5 A contact rating for size 22), endurance (500 mating cycles), shock and vibration limits, and climatic data such as –5 °C to +175 °C operating temperature and IP‑rated sealing.
