AVX's traditional battery connectors have been used for years in a number of applications' battery packs, removable or pluggable modules, and conventional board-to-board to connect both signal level and power circuits. These ultra-reliable and robust gold-plated beryllium copper (BeCu) contacts provide high integrity connections in hash environments. The unique contact design of the vertical mate 9155-800 series eliminates end user damage by deflecting cleanly and easily when pluggable modules or packs are pressed down vertically into a base unit. Traditional right angle connectors have contact geometries that rely on the pack being inserted at an angle and then rotated down into position.
