The Omega product series consists of a family of connectors qualified to the MIL-C-26500 general purpose specification. The Omega line has been expanded to also include many qualified products to numerous Boeing BACC45/BACC63 connector specifications. Utilizing the MIL-C-26500 mating interface, Cinch has also designed a high performance series of connectors with attributes for shielding, environmental sealing, fluid resistance, and vibration - namely our CN0966/ CN0967/CN1020/CN1021/CN0909 connectors. Our CN0942/CN0944 fixed contact receptacle connectors are designed specifically for custom board mount, flex circuit, and soldered wire applications. These CN series of connectors are designed to meet all electrical and mechanical requirements of the MIL-C-26500 military specification.
The C48 Series describes a family of connectors qualified to MIL-C-26500. While maintaining the MIL-C-26500 mating interface, this product has also been expanded to include qualifications to numerous Boeing specifications to satisfy general purpose requirements and unique product challenges for shielding, environmental sealing, fluid resistance, and vibration. The expanded Cinch C48 product family offers numerous product options qualified to Boeing high-performance requirements and product solutions developed for alternate termination styles/low-profile packaging.
