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.
In modern applications—from defense and security to medical and industrial fields—Miniature connector is a growing demand. The AMC High-Density A1 connector series meets this challenge by delivering the highest contact density in the smallest possible form factor. With diameters ranging from 10 mm to 18.5 mm, and contact configurations supporting power, signal, and high-speed data, the connector fits perfectly into handheld or body-worn devices.
