Frequently Asked Questions
What is the pitch and contact count of the SFM-143-L2-H-D socket strip?
The SFM-143-L2-H-D features a 0.050 inch (1.27 mm) pitch with 86 positions arranged in a dual-row configuration. This high-density layout provides reliable electrical connections across 43 positions per row, making it ideal for compact PCB designs requiring many signal channels in a small footprint.
Which PCB assembly methods are compatible with the SFM-143-L2-H-D from SAMTEC?
The SFM-143-L2-H-D is designed for surface-mount technology (SMT) assembly, compatible with standard reflow soldering processes. Its SMT footprint supports automated pick-and-place placement on PCBs, and the connector's 86 positions can handle high-density interconnect layouts at 0.050 inch pitch for telecom and industrial boards.
How does SFM-143-L2-H-D compare to single-row socket alternatives in terms of contact density?
The SFM-143-L2-H-D dual-row design offers 86 contacts at 0.050 inch pitch, roughly doubling the contact density compared to single-row alternatives in the same board length. This makes it highly space-efficient for applications requiring 86 signal or power connections, such as server backplanes, test fixture boards, and data acquisition systems with many I/O channels.
What applications benefit most from the SFM-143-L2-H-D high-reliability socket strip?
High-reliability industrial control, telecommunications infrastructure, embedded computing, and test and measurement equipment benefit most from the SFM-143-L2-H-D. Its 86-position dual-row layout at 0.050 inch pitch supports high channel-count signal routing, and gold-plated contacts provide consistent low-resistance connections across thousands of mating cycles in demanding environments.
