Product QM C Series Metal Push Pull Connectors are rugged self-locking circular connectors designed for outdoor, coastal, marine and harsh-environment applications. With an all-metal structure, IP68 waterproof performance and long-lasting salt spray resistance, the C series provides reliable power and signal transmission in humid, rainy, coastal and temporary submerged environments.
A key advantage of the C series is its patented segmented locking structure. This design provides clear tactile feedback during mating, helping operators confirm a secure connection more easily in field conditions. It also helps prevent cross-mating between similar connectors, improving connection accuracy and reducing the risk of equipment damage caused by incorrect plugging.
Compared with general harsh-environment connector series, QM C series connectors are especially suitable for equipment that requires frequent mating, secure operation, waterproof protection and flexible cable assembly. With shock and vibration resistance, wide temperature adaptability, long mechanical lifespan and adjustable cable diameter support, the C series is a dependable interconnection solution for outdoor professional equipment.

QM can help recommend a suitable C Series Metal Push Pull Connector solution with reliable locking, anti-cross-mating protection and flexible cable assembly support.
A C series metal push pull connector is a rugged circular connector with a push-pull self-locking structure, designed for outdoor, coastal, marine and harsh-environment applications requiring waterproof protection and secure mating.
The C series features a patented segmented locking structure that provides clear tactile feedback and helps prevent cross-mating between similar connectors. It also offers IP68 waterproof performance, salt spray resistance and adjustable cable diameter support.
The K series focuses on rugged outdoor and field applications with strong durability, vibration resistance and high-current capability. The C series places more emphasis on safe mating feedback, anti-cross-mating, IP68 waterproof protection, salt spray resistance and flexible cable assembly.
Yes. QM C series connectors are suitable for coastal and marine applications thanks to their IP68 waterproof performance and long-lasting salt spray resistance.
Yes. The C series is designed for humid, rainy, coastal and temporary submerged environments. For long-term underwater use or higher-pressure underwater applications, the exact sealing requirement should be reviewed before selection.
The adjustable cable diameter design gives engineers more flexibility when selecting cables, making assembly and wiring easier for different equipment structures and cable specifications.
Yes. QM can provide cable matching, wire soldering, shielded cable assembly and harness support according to cable diameter, pin layout, application environment and equipment installation requirements.
