Frequently Asked Questions
What is the total pin count and pitch of the SFM-128-02-F-D-A-P-TR connector?
The SFM-128-02-F-D-A-P-TR has 56 total positions arranged in 2 rows of 28 contacts each with a 1.27 mm (0.050 inch) pitch. This configuration spans a board footprint of approximately 36 mm in length, providing a compact high-pin-count interface for module-to-module and mezzanine board connections in space-constrained electronic systems.
How does the polarizing peg on the SFM-128-02-F-D-A-P-TR prevent assembly errors?
The P suffix designates a polarizing peg that protrudes from the connector body, fitting into a matching hole on the mating connector or PCB. This mechanical key prevents 180-degree misorientation during 56-pin dual-row mating, protecting fine-pitch 1.27 mm contacts from bent pins and ensuring correct signal alignment in applications where board replacement or field servicing occurs frequently.
For which high-reliability markets is the SFM-128-02-F-D-A-P-TR connector specifically designed?
SAMTEC positions the SFM series as high-reliability connectors targeting aerospace, defense, and industrial markets where contact integrity is required over thousands of mating cycles. The gold-plated contacts support a minimum of 500 mating cycles while maintaining contact resistance below 20 milliohms, meeting the durability requirements of military and avionics equipment subjected to vibration and thermal cycling.
What SMT reflow compatibility should designers confirm before using SFM-128-02-F-D-A-P-TR?
The SFM-128-02-F-D-A-P-TR with F-type flat leads is designed for reflow soldering at peak temperatures up to 260°C per IPC J-STD-020 MSL compliance. The 1.27 mm pitch flat lead style requires accurate stencil printing with apertures sized for 0.6 mm-wide solder pads to achieve consistent solder joint formation across all 56 positions without bridging adjacent contacts during the reflow process.
