The 146898-2 application field and working principle is a part of the Rectangular Connectors Arrays, Edge Type, Mezzanine (Board to Board) competitive family from Samtec. The 146898-2 is a right angle mezzanine header with positive lock feature. It is designed to utilize edge-to-edge card-to-card vertical connections of two boards, saving up to four card slots.The 146898-2 family consists of a complementing stackable header and socket system. The stackable configuration allows multiple boards to be stacked together while providing a secure, vertical locking connection that meets PCI Express (PCIe), Advanced Systems Memory Interface (AIMI), and Logic eXtended (LEX) electrical specifications. The 146898-2 family also supports both surface mount (SMT) and low profile through-hole (THT) mounting options.The 146898-2 system from Samtec is designed to meet the stringent requirements for high-speed current and signal transmission. The 146898-2 connector family features a 5-row, 40-position array, and supports differential signaling. Additionally, the connectors support common sizes for industry standard board-to-board data transmission. The connector system has a rated current of 8A and has an operating temperature range of -55°C to 125°C.The 146898-2 system provides excellent electrical performance, reliable mating and easy installation. It features a positive lock contact termination and utilizes a dielectric material for protection of the contacts. The multi-finger contact to mating face design increases the termination life expectancy and reduces surface contact resistances. The system is designed with polarizing features to ensure proper alignment and mating of the two boards. It features quick-turn PCB Fasteners that enable the user to quickly and easily mount the boards. The 146898-2 system is available in a variety of configurations to suit different applications. It also features a color coded shroud that identifies the different signals and/or ports. Samtec offers multiple accessories and tools to facilitate the installation of the system including mating pins, terminals and rework tools.
