Product details

Board-to-board socket for tight z-height budgets

The connector accepts a matching 0.100" pitch male pin header (square pins) and is keyed by the dual-row layout — the bottom or top entry orientation means the socket can be mounted on either side of the board, which helps when the stack-up reverses the mezzanine order.
