Frequently Asked Questions
How does the 1.27 mm (0.050 inch) pitch of the SFM-148-T2-STL-D-A benefit high-density PCB designs?
The 1.27 mm pitch of the SFM-148-T2-STL-D-A allows 96 contact positions to fit within a much smaller board footprint than equivalent 2.54 mm pitch connectors, roughly halving the connector length for the same pin count. This enables high-density board-to-board interconnects in compact embedded systems, FPGA daughter cards, and ruggedized computing modules where available PCB real estate is limited.
What does the screwlock (STL) retention feature of the SFM-148-T2-STL-D-A add to mechanical reliability?
The screwlock (STL) retention feature provides a positive mechanical lock between mated connector halves using screws that prevent inadvertent disconnection under vibration, shock, or cable pull forces. This is essential in aerospace, military, and industrial applications where the mated assembly may experience sustained vibration levels exceeding 10 g or shock events that would otherwise cause standard friction-fit connectors to disengage, potentially interrupting mission-critical signal paths.
In which aerospace or defense board architectures is the SFM-148-T2-STL-D-A a strong fit compared to lower-density connectors?
The SFM-148-T2-STL-D-A is a strong fit in VME, VPX, or custom mezzanine card architectures where high channel counts over 48 signals per row are needed within the restricted board edge dimensions of 3U or 6U card formats. Its 96 positions at 1.27 mm pitch consolidate what would require multiple lower-density connectors into a single screwlocked assembly, reducing connector count and improving overall board reliability in defense avionics and ruggedized embedded computing platforms.
