High-performance circular connectors for motorsport and UAV applications

Lane Electronics can supply Eaton standard or 8STA connectors produced to customer’s precise demands on very short lead times. The Souriau 8STA circular connectors share the same materials and design characteristics with larger mil-spec connectors such as the D38999. They will perform reliably under extreme conditions and are created particularly for applications where high performance, small size and light weight are essential.

Typical applications cover motorsport and UAV, engine control units, portable communications equipment and data acquisition systems. The 8STA Size 01 offered is the smallest circular connector with three #26 removable contacts and is an excellent solution for size and weight reduction in extreme vibration environments.

Key features of the connector range include 13 shell sizes with up to 128 contacts from 3A to 200A and six or seven colour-coded keyway orientations. The free and panel-mount shell styles include a compact integrated back shell for a heat shrink boot, and the fixed halves are offered with dual or space-saving single hole panel-mount fixing. The secure one-third turn positive locking mechanism is further enhanced with clearly visible colour indicators that show when the connector is fully locked. At the same time, quick-release and blind-mate versions offer added versatility where access is restricted.

The series is rated for an operating temperature range of -55C to +175C, 500 mating cycles, 300g shock for 3ms (EIA-364-27) and vibration of 147m/s2 at 10Hz to 2000Hz. There is a selection of rugged plated aluminium bodies or an unplated composite body to give long service in the harshest environments. Mated connectors are sealed to IP67, while hermetic versions, including feedthroughs, offer reliable barrier sealing when unmated. Versions with special fuel-resistant inserts give additional resistance to immersion in fuel with no loss of performance.
