This rugged miniature circular connector is engineered for extreme environments, offering a robust break away mechanism for quick disconnect. Waterproof when mated and unmated, it ensures reliable signal integrity and EMI shielding. Fully compatible with AMC Easy Clean systems.
The quality and structure of the cable, cabling process, and cable length are critical factors that directly influence the performance of your interconnect solution. The interface between the cabled connector and the device’s transmitter and receiver is also essential to ensure that the entire system meets your industry standards and operational requirements.
The AMC High Density A1 plug combines extremely compact size with maximum electrical performance, making it ideal for military and rugged field applications. Designed for quick-disconnect (break-away) functionality, IP68 waterproof sealing, and up to 40 contacts in a single unit, it ensures signal integrity and mechanical resilience even under the most demanding conditions. This miniature solid connector is tested to MIL standards, offering robust protection against vibration, dust, and moisture, while its color-coded mechanical keying guarantees secure and intuitive mating.
The LINKHIVE K Series FGG connectors are precision-engineered circular push pull connectors designed for outdoor and exposed environments. Featuring rugged full-metal construction and IP68 sealing, these watertight brass connector protect against water, dust, and mechanical shock, making them ideal for mission-critical applications.
This IP68 connector ensures complete sealing against water ingress, even during temporary submersion. Its robust housing is ideal for use in rain, mud, and chemically aggressive environments, commonly encountered in defense, medical, and broadcast fields.
The LINKHIVE K Series incorporates a proven self-latching connector mechanism that guarantees secure and quick mating/unmating. This makes it ideal for systems requiring repeated disconnections under time-sensitive or high-vibration conditions.
