SIAL description

SIAL is a modular high-density interconnection system developed by Amphenol Socapex for use in severe environments, such as commercial and military aerospace and C5ISR applications. This hybrid connector is designed to work with thermal clamps and exceeds MIL-DTL-55302 requirements, making it a robust and reliable technology. SIAL comes in 13 different arrangements with 18 to 392 contacts. Additionally, SIAL features a low-profile board-to-board connector with lateral rails that protect the male contacts from external damage, and ESD protection on both the plug and receptacle. One of the key features of SIAL is its hybrid configurations, which allow for mixing of signal, power, and RF contacts. The contact technology used in SIAL also enables lateral displacement of up to +-0.25 mm, providing flexibility in design and assembly. Overall, SIAL is a versatile and rugged interconnect system that can handle demanding applications in harsh environments.
