Circular Connectors

Y27 Series

Our Y27 series connectors adhere to the rigorous national military standard GJB2905-97 and the US military standard MIL-C-38999. Featuring a user-friendly push/pull coupling mechanism, these connectors are crafted from high-quality materials including aluminum alloy, naval brass, and stainless steel. With a wide range of 13 shell sizes, 18 contact arrangements spanning from 1 to 121 contacts, and 10 current ratings from 3A to 250A, the Y27 series circular connectors offer unmatched versatility and adaptability.

Engineered for seamless connection and effortless disconnection, our Y27 series connectors excel in blind mating and various challenging scenarios. They exhibit exceptional resistance to vibration, salt spray, and electromagnetic interference, while also offering other special models (dust-resistant, rain-resistant, and gas sealing). Widely utilized in the aerospace, aviation, marine, field operations, power distribution, railways, and telecommunication sectors, the Y27 series connectors provide reliable connectivity solutions that fuel progress across industries.
