Key Features
- 62-position dual-row socket at 0.050" (1.27 mm) pitch for high pin-count fine-pitch mating in compact SMT assemblies
- Tall 'H' mating height variant providing increased board-to-board clearance for thick PCBs or components between stacked boards
- High-reliability SFM series construction with consistent contact normal force for stable electrical performance across mating cycles
Applications
The SFM-131-T2-H-D-A-K is deployed in multi-layer backplane assemblies, high-density data acquisition modules, and industrial computing boards requiring 62-pin fine-pitch connectivity with elevated stack spacing. The tall mating height variant accommodates board assemblies where tall components such as capacitors or heat sinks occupy the space between stacked PCBs. Its 0.050" pitch design provides maximum signal density within a connector footprint under 40 mm in length.

Frequently Asked Questions
How many signals per row does SFM-131-T2-H-D-A-K support, and how long is the mating area?
The SFM-131-T2-H-D-A-K provides 62 positions in a dual-row arrangement with 31 contacts per row at 0.050" (1.27 mm) pitch. The total mated connector length is approximately 39.37 mm (31 x 1.27 mm), enabling 62-channel parallel interfaces in a footprint under 40 mm for high-density data acquisition and backplane applications.
What board-to-board clearance does the 'H' (tall) mating height variant of SFM-131-T2-H-D-A-K provide versus a standard-height SFM?
The 'H' suffix on SFM-131-T2-H-D-A-K indicates a tall mating height, which typically provides 11 mm to 15 mm of board-to-board spacing when mated, compared to standard-height variants that offer approximately 8 mm. This extra clearance of 3 mm to 7 mm accommodates through-hole components, tall capacitors, or thermal pads mounted on the inner surfaces of stacked PCBs.
For a data acquisition board needing 60 analog channels, is SFM-131-T2-H-D-A-K a suitable interconnect?
Yes, with 62 positions the SFM-131-T2-H-D-A-K can carry 60 analog channels plus 2 ground return lines, or 56 channel signals with 6 shield or reference pins, all within a 39.37 mm long connector at 1.27 mm pitch. For 16-bit ADC data acquisition at sample rates below 100 MHz per channel, this fine-pitch socket provides adequate signal density and contact reliability.
How does SFM-131 (62-position) compare to SFM-123 (46-position) when expanding a system from 40 to 60 signal interfaces?
Upgrading from SFM-123 (46 positions) to SFM-131 (62 positions) adds 16 extra signal pins, increasing the connector length by approximately 20.32 mm (16 x 1.27 mm) while maintaining the same 0.050" pitch. If the system design needs 41 to 62 signals, SFM-131 is required; for 46 or fewer, SFM-123 is sufficient and saves 20 mm of board length on the connector footprint.
