Linconn's GL (also known as HR) series are multi-pin high-performance circular connectors renowned for their modular design and high reliability. Featuring a bayonet quick-lock mechanism (locked with a ¼-turn rotation), this series is ideal for applications requiring frequent connection/disconnection, such as test equipment, aviation ground support, generator sets, and broadcast vehicles. The metal housing provides excellent shielding and mechanical protection, while the contact modules can be configured for signals, power, coaxial, or even fiber optics, enabling high customization.
