What are the key features of TFM-124-01-LM-D-A-P-TR?
- 48-position dual-row .050" (1.27 mm) pitch LM low-profile SMT connector with A alignment posts for precise reflow registration and P polarization pegs preventing misorientation
- Tape-and-reel (TR) packaging enables seamless integration into automated SMT pick-and-place lines for high-volume PCB assembly
- Tiger Eye contact system with low-profile LM style minimizes connector stack height for use in space-constrained mezzanine designs with tight z-axis clearance
What is TFM-124-01-LM-D-A-P-TR used for?
The TFM-124-01-LM-D-A-P-TR is used in high-density mezzanine cards, server blade modules, and compact communication systems where a 48-pin .050" pitch dual-row SMT connector must combine low profile with automated assembly compatibility. The LM low-profile contacts keep the connector height minimal, enabling use in stackups with less than 4 mm between boards. Alignment posts and polarization pegs reduce placement errors in automated lines, improving first-pass yield in high-volume production.

Frequently Asked Questions
What does the LM contact style contribute to the TFM-124-01-LM-D-A-P-TR's suitability for tight mezzanine stackups?
The LM low-profile contact style reduces the overall mated height of the TFM-124-01-LM-D-A-P-TR connector pair to less than 4 mm, enabling mezzanine board stackups where 48 signals must cross a very narrow gap between the main board and daughter card. Standard TFM contacts would require additional clearance, making the LM variant essential for ultra-compact server blade and embedded computing modules.
How do the A and P features on TFM-124-01-LM-D-A-P-TR support high-yield SMT production?
The A alignment posts on TFM-124-01-LM-D-A-P-TR locate the connector body to the PCB land pattern within approximately 0.1 mm during reflow, preventing the 48-position .050" pitch connector from drifting before solder solidifies. The P polarization pegs ensure the connector can only be placed in the correct orientation, eliminating a common assembly defect that would require costly rework of densely routed mezzanine PCBs.
For a 48-pin high-speed interface on a compact module, when would TFM-124-01-LM-D-A-P-TR be preferred over TFM-114-01-S-D-A-P-TR?
TFM-124-01-LM-D-A-P-TR is preferred when the design requires 48 positions rather than 28, and when the LM low-profile contact style is needed to achieve a mated stack height below 4 mm. Both connectors share the same .050" pitch, dual-row layout, and tape-and-reel TR packaging, so the choice reduces to contact count and acceptable mated height in the enclosure.
