Frequently Asked Questions
What pitch and contact count does the SFM-122-L2-L-D-A-K offer?
The SFM-122-L2-L-D-A-K features a 0.050 inch (1.27 mm) pitch with 44 total contacts arranged in a dual-row configuration of 22 positions per row, making it ideal for high-density SMT interconnect designs.
How does the kinked tail option on the SFM-122-L2-L-D-A-K benefit PCB assembly?
The K (kinked) tail variant provides a mechanical interference fit that holds the connector in place on PCB pads before and during reflow soldering, reducing placement errors in automated SMT assembly lines handling 44-pin components.
For which types of module-to-carrier board applications is the SFM-122-L2-L-D-A-K suitable?
This connector suits applications where compute or I/O modules mate to carrier boards, such as embedded single-board computers, FPGA daughtercards, and industrial data acquisition modules requiring reliable 44-pin dual-row SMT socket connections at 1.27 mm pitch.
What is the mating connector family compatible with the SFM-122-L2-L-D-A-K?
The SFM-122-L2-L-D-A-K mates with SAMTEC TSM or TFM series male header strips at 0.050 inch (1.27 mm) pitch with matching 44-pin dual-row pinouts, enabling stacking heights from approximately 0.1 inch to several millimeters depending on mated pair selection.
