Frequently Asked Questions
How many positions and what is the pitch of the SFM-122-T2-FM-D-A-K-TR connector?
The SFM-122-T2-FM-D-A-K-TR provides 44 total positions arranged in a dual-row configuration on a 0.050-inch (1.27 mm) pitch. This fine pitch enables very high connector density on compact PCBs, supporting up to 22 signals per row in a small board footprint.
What mounting style and packaging does the SFM-122-T2-FM-D-A-K-TR use, and how does that affect assembly?
The connector uses surface-mount technology (SMT) and is supplied in tape-and-reel (TR) format, making it compatible with automated pick-and-place assembly lines. This eliminates the need for through-hole drilling and reduces assembly time, which is particularly advantageous in high-volume production runs of 1000 pieces or more.
In which board-to-board stacking or mezzanine applications is the SFM-122-T2-FM-D-A-K-TR commonly used?
This socket strip is widely used in mezzanine module interconnects, FPGA daughter-card interfaces, and test fixture probe interfaces where 44 signals at 0.050-inch pitch must be reliably transferred between two PCBs. The high-reliability socket design supports repeated mate/unmate cycles, making it suitable for prototyping fixtures and field-replaceable module sockets.
What is the current rating per contact, and what signal speeds can the SFM series handle?
SAMTEC SFM series contacts are rated for approximately 1 A per pin at operating temperatures up to 105°C, and the controlled-impedance design supports high-speed differential signals up to several GHz depending on trace routing. This makes the connector suitable for USB 3.0, PCIe Gen 2, and similar multi-gigabit serial protocols in compact embedded systems.
