Presentation
MIL-DTL-83723 was designed to be a high temperature, high vibration withstanding connector, but had some important
drawbacks:
- Uncertain bottoming, - No torque specication,
- Risk of unlocking under vibration, - No scoop proof versions.
To improve on these drawbacks, EN2997 standard includes:
- 360° teeth enable additional backshell positions, - Improved shielding resistance due to shell to shell bottoming,
- Additional barriers to leakage. - Self locking mechanism on every plug allows a higher resistance to vibration,
SOURIAU enhanced the standard denition with some additional features:
- Thermoplastic material achieves a better insulation - Qualied as per EN2997 for both stainless steel and aluminum versions,
resistance and a high resistance to standard re tests, SOURIAU has one of the widest ranges on the market.
SOURIAU made these improvements to give our customers the best choice for procuring high performance connectors.
