Product QM K Series Metal Push Pull Connectors are rugged self-locking circular connectors designed for security, defense, marine, outdoor industrial and harsh-environment equipment. With a compact all-metal structure, the K series combines high mechanical strength, space efficiency and secure push-pull locking performance, making it suitable for modern field equipment, vehicle-mounted systems and portable outdoor devices.
Compared with compact metal series focused mainly on installation space, the K series is built for more demanding environmental conditions. It provides strong resistance to corrosion, vibration and shock, while supporting stable connection performance in outdoor, coastal, mobile and high-load operating scenarios.
Following international standard dimensions, QM K series connectors can support direct interchange and replacement with mainstream industrial connector interfaces. With reliable high-current transmission capability, long service life and wide temperature adaptability, the K series provides durable interconnection support for equipment that must operate safely and continuously in demanding professional environments.
