Lemo Connector L and S Series

A range of products dedicated to applications in which connectors need to function even in case of rotation. Similar to coaxial or triaxial connectors, these precision-engineered connectors are fitted with multiple concentric electrical contacts.

The number of contacts ranges from 4 to 10contacts. Connectors are available in various shell sizes. For an IP68 connector, the solution selects the E series.

These contacts, designed for low-speed rotation, can last up to 10,000 rotation cycles. Unlike coaxial or triaxial connectors this range is not impedance controlled.

The contacts are recessed and scoop-proof. Applications include petroleum downhole drilling systems and turret applications, in other words, applications where the connection may require free rotation (instrumentation mast).
