SFM-144-L2-LM-D-LC SAMTEC Connector (Other) In Stock

What are the key features of SFM-144-L2-LM-D-LC?

• 88 contacts in 2 rows on 1.27 mm (0.050 inch) pitch achieves twice the pin density of 2.54 mm pitch connectors in the same board area
• High-reliability socket design with locking mechanism (LC) prevents accidental unmating in vibration-prone industrial and aerospace environments
• Surface-mount termination enables automated reflow soldering at up to 260°C peak for high-volume SMT production
• L2 stack height option sets precise 2 mm board-to-board spacing for controlled-impedance signal layers in tight enclosures
• Dual-row SMT socket is the female mating half for SAMTEC TSM and SFM-series male pin strips on the same 0.050 inch pitch

What is SFM-144-L2-LM-D-LC used for?

The SFM-144-L2-LM-D-LC is used in high-density mezzanine interconnects on military, aerospace, and industrial computing PCBs where 88 signals must be transferred across a board-to-board interface at 1.27 mm pitch with positive retention against vibration. Its locking feature and precise 2 mm stack height make it suitable for rugged embedded modules, FPGA mezzanine cards, and radar processing boards where accidental connector separation could cause system failure. It is also popular in medical imaging equipment and automated test fixture heads that require repeatable, low-insertion-force mating over thousands of cycles.
