Ruggedized Amphenol FC1820P2SAA14 connector ideal for aerospace military and satellite power systems
Positronic SP MAX Rugged Power & Signal Connectors
Product Overview
The Positronic SP MAX series offers rugged power and signal connectors specifically engineered for demanding applications in military, space, satellite, and commercial air sectors. These connectors feature precision-machined shells for robust EMI/RFI protection and the flexibility to accommodate a variety of contact sizes (#12, #16, #18, and #22) within a single unit. Designed for performance compatibility with EN4165, ESA/ESCC-3401, and DO-160 standards, the SP MAX series ensures reliable operation in harsh environments, including deep space and planetary-based communications. Key features include liquid crystal polymer insulators for wide temperature range operation, high current ratings per contact, integral blind mating capabilities, and multiple termination options. The slim metal housing aids in heat dissipation and shielding, while various hardware and accessory options allow for customized solutions in power and signal I/O, LRUs, battery and solar power distribution, and high-wattage power supplies.
