Frequently Asked Questions
How does the keyed (K) feature on SFM-102-T2-S-D-A-K protect 4-position SMT assemblies from mis-mating?
The K (keyed) polarization on the SFM-102-T2-S-D-A-K physically blocks 180-degree reversed insertion across all 4 dual-row contact positions, ensuring correct signal alignment every time. This is especially valuable in dense 0.050" (1.27 mm) pitch assemblies where visual verification of orientation is difficult during PCB bring-up or field maintenance.
What board-to-board stack height does the T2 designation imply for SFM-102-T2-S-D-A-K?
The T2 designation in the SFM-102-T2-S-D-A-K specifies the mated stack height between the two boards. The T2 SFM series is designed for a defined board-to-board separation, enabling PCB assembly designers to calculate precise 2-board stack dimensions when integrating 4-position dual-row 0.050" pitch socket-and-plug pairs in compact module designs.
For which sensor or embedded module applications is SFM-102-T2-S-D-A-K an appropriate socket choice?
The SFM-102-T2-S-D-A-K is appropriate for 4-signal-channel sensor interface modules, MEMS sensor boards, and small plug-in function modules requiring 4-position dual-row SMT connectivity at 1.27 mm pitch with guaranteed keyed polarization — covering applications in industrial IoT, medical diagnostics, and wearable electronics platforms.
How does SFM-102-T2-S-D-A-K at 0.050" pitch compare to 0.100" pitch alternatives for signal density?
At 0.050" (1.27 mm) pitch versus 0.100" (2.54 mm) pitch, the SFM-102-T2-S-D-A-K fits the same 4 dual-row contacts into half the board footprint length, reducing occupied PCB area and enabling tighter integration with adjacent SMD components. This makes it the preferred choice for miniaturized module designs where board space is critically constrained.
