QM Metal Push Pull Connectors are high-reliability circular connectors designed for demanding applications that require strong mechanical durability, secure mating, stable signal transmission and long service life. Built with high-quality metal housings and precision-engineered internal structures, this product range is suitable for medical equipment, industrial systems, outdoor devices, security and defense equipment, optical instruments, transportation systems and other professional applications.
Most QM metal push pull connectors support up to 10,000 mating cycles, making them suitable for high-load, frequent-connection and long-term operating environments. For harsh conditions such as outdoor installations, humid environments, underwater applications, vibration-intensive equipment and vacuum-related systems, IP68-rated variants, low-leakage structures, flange-mount designs and anti-rotation locking options are available.
The series also supports advanced electrical and hybrid transmission requirements. With high-performance PEEK inserts, QM metal connectors provide excellent insulation performance, stable signal integrity and strong adaptability for customized contact layouts. Optional customized inserts can support 10G high-speed signal transmission and hybrid integration such as optoelectronic, coaxial, high-low voltage, fluid-electric and pneumatic-electric configurations.
