3M Boardmount Socket 1502 Series
The 3M Boardmount Socket 1502 Series offers a 2 mm x 2 mm pitch connector designed for surface mount, straight, and right-angle plated through-hole applications. These sockets feature a high-temperature insulator, reflow solder compatibility, and a low profile to minimize PCB stack height. They are end stackable, with through-hole versions also being side stackable. SMT parts are available in tape and reel packaging with a vacuum cap for automated placement. This series is suitable for applications requiring reliable board-to-board interconnects.
