Frequently Asked Questions
How many pins and what pitch does the TFM-137-03-S-D-RA support for board-to-board connections?
The TFM-137-03-S-D-RA provides 74 pins arranged in a dual-row layout on a 0.050-inch (1.27 mm) pitch, delivering 37 contacts per row for very high-density signal routing in backplane, data communications, and industrial computing applications where maximizing connection count in a compact footprint is critical.
Which rack-mounted or stacked-board system designs benefit most from the TFM-137-03-S-D-RA right-angle orientation?
The TFM-137-03-S-D-RA's right-angle mounting routes all 74 pins parallel to the PCB surface toward the board edge, enabling accessible connections in rack-mounted industrial systems, chassis-enclosed defense equipment, and stacked board assemblies where vertical clearance is limited and edge-accessible signal routing is required.
How does Tiger Eye contact technology in the TFM-137-03-S-D-RA ensure long-term signal integrity?
Samtec's Tiger Eye contacts use a wiping mating action that maintains contact resistance below 20 mOhm across the full 74-pin interface, even after repeated insertions. This ensures consistent signal integrity in mission-critical applications including aerospace data buses, defense electronics, and high-speed data communications modules subjected to vibration and temperature cycling.
