Frequently Asked Questions
What is the pitch and row configuration of SFM-137-L2-FM-D-A?
The SFM-137-L2-FM-D-A features a 0.050" (1.27 mm) pitch dual-row arrangement with 74 total positions, providing a high pin count in a compact surface-mount footprint suitable for dense PCB layouts.
In which industrial applications can SFM-137-L2-FM-D-A provide a reliable board-to-board connection?
This connector is ideal for telecom line cards, industrial PLC backplanes, and automated test equipment where 74 signal channels at 0.050" pitch must be routed reliably. Its gold-plated contacts maintain low contact resistance even after hundreds of mating cycles.
How does SFM-137-L2-FM-D-A compare with single-row SMT socket strips when pin count requirements exceed 37 pins?
The dual-row design of SFM-137-L2-FM-D-A accommodates 74 positions within the same board length as a 37-pin single-row strip, roughly halving the PCB footprint length while maintaining 0.050" pitch and SMT mounting compatibility.
