EMCA’s connector accessories are designed to deliver mechanical protection, EMI/RFI shielding, and environmental sealing in high-performance connector systems. Our products support a wide range of harsh-environment and high-reliability applications, including:
  • MIL-DTL-38999 Series III and MIL-DTL-26482 Series II and other circular connector platforms: Our accessories are designed to seamlessly integrate with and enhance the performance of these critical connector standards, ensuring signal integrity and system longevity.
  • Aerospace harness assemblies: For critical aerospace harness assemblies, our connector accessories are meticulously engineered. Backshells provide essential EMC shielding and rugged strain relief, ensuring signal integrity and protecting against electromagnetic interference in mission-critical systems. Additionally, protective caps offer vital sealing for unmated connectors during storage or flight, while dummy receptacles provide safe, secure storage for unused plugs, preventing damage and ensuring system integrity even in the most demanding airborne environments.
  • Industrial and mobile equipment: EMCA's connector accessories are designed to ensure reliable performance for industrial and mobile equipment operating in exposed or demanding conditions. Protective caps offer superior environmental sealing against dust, liquids, and temperature extremes for inactive ports. Backshells provide robust mechanical protection and strain relief for active connections, while dummy receptacles serve as secure storage for unplugged connectors, all contributing to the durability needed for heavy machinery, outdoor installations, and portable electronic systems.
  • Shielded enclosures and electronic systems. Our connector accessories are vital for fortifying shielded enclosures and sensitive electronic systems that demand superior EMI protection and proper grounding. Backshells play a crucial role in providing comprehensive electromagnetic shielding, diverting interference away from sensitive circuits. Meanwhile, protective caps can offer sealing for unused ports to maintain the enclosure's integrity, and dummy receptacles ensure secure, grounded storage for detached plugs, collectively maintaining system stability and data integrity in environments prone to electrical noise.
  • Connectors subject to vibration, moisture, or electromagnetic interference. Our comprehensive range of connector accessories is specifically developed to fortify connectors against the most common threats to reliability. Backshells provide robust protection from constant vibration, preventing mechanical failure and ensuring stable connections. Protective caps offer superior sealing against moisture ingress for unmated connectors, preventing short circuits and corrosion. And for both active and inactive ports, backshells and specialized caps deliver critical shielding to mitigate the effects of harmful electromagnetic interference (EMI), ensuring uninterrupted performance and longevity in harsh operating conditions.
These accessories, such as backshells, dummy receptacles, and protective caps are critical for maintaining signal integrity, system reliability, and cable longevity in extreme environments.
