5120587-2

A 5120587-2 is a rectangular connector array–typically comprising two connectors, one on the host board and the other on a daughter board. This type of connector is designed to provide a means of electrical interconnection between two printed circuit boards, allowing potential applications such as board stacking, board expansion, or even signal routing in a system. It gets its name from its two-row, 14-pin design.

The 5120587-2 was designed to provide an open and robust board-level interconnect which allows the host board to mount a daughter board into system design without any relative mechanical retention force. The “double cantilever” design of the connector further ensures a secure connection between both boards. The host connector is firmly secured to the host board, while the daughter connector features two contact fingers which align with the mezzanine mating hole and provide a secure locking mechanism. This robust and easy-to-use connecting system makes the 5120587-2 ideal for low-cost mezzanine board applications.

The 5120587-2 Connector features two-row design, 14-pin counterbored through-hole contacts which mate to either a 14-pin gold-plated female contact. It is rated to handle up to 6.25A, and has an insulation resistance of 1000 megohms minimum. The mated parts can be soldered-in-place; or the socket can be removed and soldered directly to the board. The socket utilizes a polytetrafluoroethylene (PTFE) insulation for low dielectric loss, and is designed for a -65°C to +125°C temperature range.

The 5120587-2 Connector is an ideal choice for board-to-board connections due to its rugged design. Its double cantilever feature provides strain relief from high vibration and prevents mechanical movement, allowing for robust connections. Its PTFE insulation ensures reliable electrical performance, while its low profile is intended to minimize the overall system height. Additionally, the use of board-edge connection eliminates the need for through-holes with expensive thru-holes and allows a more efficient layout, as well as improved board stacking. In terms of cost, the 5120587-2 Connector is a superior choice for customers looking for economical board-to-board connections.
