What are the key features of SFM-120-L2-LM-D-A-P-TR?
- 40-position dual-row socket strip at 1.27 mm (0.050") pitch for high-density SMT board-to-board interconnection
- Latch-mating (LM) retention mechanism ensuring secure connector engagement and resistance to vibration-induced unmating
- Low-profile L2 design reducing mated assembly height for compact enclosure-mounted PCB stacks
- Tape-and-reel (TR) packaging compatible with automated SMT pick-and-place assembly at volume production rates
What is SFM-120-L2-LM-D-A-P-TR used for?
The SFM-120-L2-LM-D-A-P-TR is suited for ruggedized board-to-board interconnects in defense electronics, industrial automation, and portable test instruments requiring 40-pin dual-row socket connectivity with secure latching. Its latch-mating retention is particularly valuable in vibration-prone environments such as vehicle-mounted electronics or airborne systems. The 1.27 mm pitch SMT footprint enables dense PCB layouts while tape-and-reel packaging supports automated high-volume production.

Frequently Asked Questions
What retention feature does the SFM-120-L2-LM-D-A-P-TR latch-mating design provide for vibration environments?
The latch-mating (LM) mechanism in the SFM-120-L2-LM-D-A-P-TR provides positive mechanical retention when mated, preventing unintentional unmating under vibration loads typical of vehicle-mounted or aerospace applications. This feature maintains connector integrity across 40 signal pins even under shock conditions exceeding 50 g peak acceleration.
How many contacts per row does the SFM-120-L2-LM-D-A-P-TR socket strip provide at 1.27 mm pitch?
The SFM-120-L2-LM-D-A-P-TR provides 40 total contacts in a dual-row configuration with 20 contacts per row at 1.27 mm (0.050 inch) pitch. The connector footprint spans approximately 25 mm in length, making it compact enough for dense multilayer PCB designs in portable and embedded computing applications.
When is the SFM-120-L2-LM-D-A-P-TR preferred over non-latching SAMTEC SFM variants for a field-serviceable module?
The latch-mating SFM-120-L2-LM-D-A-P-TR is preferred when a field-serviceable module must withstand repeated plug-unplug cycles of 50 or more without loosening, as the latch provides consistent 40-pin retention force across the product service life. Non-latching variants are suitable for bench setups but risk signal dropout under vibration above 10 g in deployed environments.
