Frequently Asked Questions
What pitch and contact count does the SFM-120-02-L-D-A-P-TR provide for high-density board interconnection?
The SFM-120-02-L-D-A-P-TR is a 40-position dual-row socket strip with 0.050 inch (1.27 mm) pitch, providing 40 individual socket contacts in a body length of only 1.125 inches and a body breadth of 0.145 inch. This compact configuration enables high-pin-density surface-mount interconnection suitable for embedded computing, carrier boards, and interface modules where PCB area is constrained.
How does the peg board mounting option benefit PCB assembly for the SFM-120-02-L-D-A-P-TR?
The peg board mounting option on the SFM-120-02-L-D-A-P-TR includes molded alignment pegs that fit into corresponding PCB holes, providing accurate mechanical positioning and preventing connector movement during solder paste reflow. This feature is especially valuable for 0.050 inch pitch surface-mount connectors where even small positional shifts can cause misaligned pad soldering. The peg-mounted design reduces rework rates in high-volume automated SMT production.
Which mating connector series pairs with the SFM-120-02-L-D-A-P-TR to form a complete 40-position interconnect?
The SFM-120-02-L-D-A-P-TR mates with SAMTEC's corresponding 0.050 inch pitch dual-row male pin strip headers from the TFM or SFM series. Using matched SAMTEC male-female pairs at 1.27 mm pitch ensures correct contact alignment, reliable low-resistance electrical continuity across all 40 positions, and consistent mechanical retention force. SAMTEC provides mated connector insertion and extraction force specifications to validate reliable operation through repeated mating cycles.
For what board-to-board signal or power applications is a 40-position 0.050 inch pitch socket like the SFM-120-02-L-D-A-P-TR well suited?
A 40-position 0.050 inch pitch socket is well suited for carrying multiple parallel digital bus signals such as a 16-bit address bus plus 8-bit data bus plus control lines, or for combining multiple SPI and UART interfaces on a single connector. It is also used for board-to-mezzanine module interconnection in embedded systems, PLC I/O modules, and FPGA daughter card designs where 40 signals must cross a board boundary in a footprint smaller than a 2.54 mm pitch dual-row header of comparable position count.
