What are the key features of SFM-140-L2-H-D-LC?
- Tiger Eye contact system for high-reliability, low-insertion-force mating in harsh environments
- Split Board Lock mechanism provides secure PCB mounting and vibration resistance in 0.050" pitch dual-row layout
- Surface-mount termination on 0.050" (1.27 mm) pitch with 80 positions (2×40) in compact 2.155" body length
What is SFM-140-L2-H-D-LC used for?
The SFM-140-L2-H-D-LC is well suited for high-density board-to-board interconnections in test and measurement equipment, industrial control systems, and data acquisition hardware. Its Tiger Eye contacts deliver consistent mating reliability in applications subject to vibration or repeated mate/unmate cycles. The 0.050" pitch dual-row format makes it a preferred choice for compact backplane and daughtercard designs where space is at a premium.

Frequently Asked Questions
What contact pitch and row configuration does the SFM-140-L2-H-D-LC use?
The SFM-140-L2-H-D-LC uses a 0.050" (1.27 mm) pitch in a dual-row arrangement, providing 80 positions total across 2 rows of 40 contacts, making it suitable for high-density PCB interconnections where board space is limited.
Which PCB mounting feature helps the SFM-140-L2-H-D-LC withstand mechanical stress during assembly?
The Split Board Lock mounting option secures the connector to the PCB, resisting up to the mechanical forces encountered during mating and handling. Combined with the surface-mount termination style, this keeps the 2.155" body firmly positioned on the board across a typical operating temperature range of -55°C to +125°C.
How does the Tiger Eye contact technology in the SFM-140-L2-H-D-LC improve connector reliability?
Tiger Eye contacts use a dual-beam wiping action that maintains a low and stable contact resistance over hundreds of mating cycles, ensuring reliable signal integrity for 80-position high-speed interfaces. This design is especially valuable in test equipment and instrumentation requiring repeatable, low-loss connections at frequencies up to several GHz.
