What are the key features of SFM-127-02-F-D-A-P-TR?
- 54-position dual-row 0.050" (1.27 mm) pitch right-angle SMT socket strip for space-efficient horizontal board-to-board mating
- Gold-flash (F) contact finish ensures contact resistance below 20 mΩ and oxidation resistance for reliable low-level signal connections
- Polarized (P) housing prevents 180° misalignment across 54 positions during PCB assembly or field board replacement
- Tape-and-reel (TR) packaging supports automated pick-and-place SMT production at placements volumes above 500 boards per reel
What is SFM-127-02-F-D-A-P-TR used for?
The SFM-127-02-F-D-A-P-TR is designed for right-angle horizontal board-to-board and board-to-cable connections in compact embedded modules, camera interface boards, and communications cards where vertical height constraints require the mating connector to enter from the side. Its 54-position 0.050" pitch footprint routes 27 differential pairs through a connector body shorter than 35 mm, making it suitable for PCIe or high-speed LVDS interfaces on small-form-factor boards. The polarized housing ensures correct orientation during both factory assembly and field upgrades of modular subsystems.

Frequently Asked Questions
What does the -A suffix on SFM-127-02-F-D-A-P-TR indicate about the connector's PCB mounting orientation?
The -A suffix designates a right-angle mounting orientation, meaning the connector body is positioned so the mating direction runs parallel to the PCB surface rather than perpendicular to it. This reduces the vertical height of the mated assembly by up to 8 mm compared to a vertical-entry socket, which is critical for slim enclosures, panel-mount boards, and camera modules where the PCB-to-enclosure clearance is under 10 mm.
How many differential pairs can the SFM-127-02-F-D-A-P-TR route through its connector footprint?
With 54 positions in a dual-row 0.050" (1.27 mm) pitch layout, the SFM-127-02-F-D-A-P-TR supports up to 27 differential pairs. At 1.27 mm pitch the total connector row length is approximately 34 mm for 27 pairs, versus 68 mm required at 0.100" pitch, enabling high-speed LVDS, MIPI, or PCIe x4 interfaces to fit on small-form-factor boards under 40 mm wide.
What contact resistance specification does the gold-flash finish on SFM-127-02-F-D-A-P-TR provide?
The -F gold-flash contact finish on the SFM-127-02-F-D-A-P-TR delivers a contact resistance below 20 mΩ per pin at the initial mating. Gold-flash coatings resist oxidation in ambient humidity up to 85% RH, ensuring that contact resistance remains stable over the service life of the connector even in unpressurized avionics bays or outdoor-rated enclosures operating between -55°C and +85°C.
When is the SFM-127-02-F-D-A-P-TR a suitable alternative to a 0.100" pitch 54-position connector on a redesigned PCB?
The SFM-127-02-F-D-A-P-TR becomes the preferred alternative when a PCB redesign must maintain 54-signal connectivity while reducing connector footprint by approximately 50%. Switching from a 0.100" pitch 54-position connector to this 0.050" pitch version shortens the connector row by roughly 34 mm, freeing space for a larger ground plane or additional component clusters. This trade-off is most cost-effective when the PCB fabrication savings from the smaller board outweigh the slightly higher per-unit price of the fine-pitch connector in production volumes above 1,000 units.
