Frequently Asked Questions
How many positions does the SFM-124-L2-STL-D-A-K-TR have and what is its contact pitch?
The SFM-124-L2-STL-D-A-K-TR provides 48 positions arranged in a dual-row layout at 0.050-inch (1.27 mm) pitch. This compact configuration allows designers to interconnect 48 signals between boards while maintaining a small PCB footprint suitable for space-constrained designs.
How does the STL option in SFM-124-L2-STL-D-A-K-TR affect the connector's mechanical profile?
The STL designation indicates a low-profile surface-mount standoff configuration, reducing overall mated stack height for slim form-factor designs. This makes it well suited for embedded modules and mezzanine boards where vertical clearance is limited to less than 5 mm above the PCB surface.
What industries and system types commonly use the SFM-124-L2-STL-D-A-K-TR connector?
This connector is used in telecommunications equipment, embedded computing platforms, and industrial automation controllers that require 48 reliable signal paths at 0.050-inch pitch. Its surface-mount SMT design supports high-volume automated assembly in server blade, FPGA expansion, and test instrumentation applications.
Can the SFM-124-L2-STL-D-A-K-TR be used for high-speed differential signal routing?
Yes, the dual-row 0.050-inch pitch layout supports controlled-impedance differential pair routing when matched with an appropriate PCB stackup targeting 100 ohm differential impedance. Signal integrity performance depends on trace routing discipline, but the connector itself is designed for high-reliability signal transmission in demanding environments.
