The SM-LC board-to-board socket is one of the connectivity solutions offered by Samtec under their STMM-112-02-G-D series of Rectangular Connectors - Headers, Male Pins. This particular model is designed to connect two boards via a pair of mating connectors. The SM-LC board-to-board socket is suitable for use in a variety of applications, from commercial to industrial, including automotive, medical and aerospace. It is an ideal connector for any high-speed or high-density communication system.

In terms of features, the SM-LC board-to-board socket is designed for low-profile and compact size, enabling it to provide a space-saving solution. It can accommodate up to 0.042 inch board-to-board center-to center spacing, with a total profile of just 0.100 inch. The socket also features a Friction Lock retention mechanism for secure and reliable mating, and a stamped seal contact that improves the contact durability. The connector is also tested to 1 million cycles mating cycles and is rated for up to 4.0A current at 500VDC.

As for the design of the SM-LC board-to-board socket, the product features rugged housing construction made from PBT (polybutylene terephthalate), with a range of other possible housing materials and color choices available. The center contact is made from a Phosphor Bronze alloy, plated with gold, while the shell plating is RoHS compliant. The socket is also designed to be compliant with IPC/JEDEC J-STD-20 specifications.

The working principle of the SM-LC board-to-board socket is fairly straightforward. To mate the two connectors, a user simply needs to line them up and press them forcefully together until they click, at which point the socket’s retention mechanism engages securely and reliably with the surface of the board. Once the connectors are mated, data is transferred between the two boards via the stamped seal contact, shielding the communication from EMI interference. In addition, the design of the socket also ensures that vibration does not cause any disconnections or data loss.

In conclusion, the Samtec STMM-112-02-G-D series SM-LC board-to-board socket is an ideal connectivity solution for numerous applications, from commercial to industrial and even aerospace. It provides an efficient, reliable, and secure way of transferring data between two boards, with its low-profile and compact design making it perfect for space-saving applications. The socket also features a robust housing construction and a selection of plating options, as well as being tested and rated to handle heavy usage.
