Key Features
- 62 contacts in a dual-row arrangement at 0.050" (1.27 mm) pitch, enabling very high density board-to-board connections
- Gold-plated contact finish (K option) providing low contact resistance and reliable performance over extended mating cycles
- Tape-and-reel (TR) packaging for seamless integration into high-speed SMT pick-and-place production lines
Applications
The SFM-131-T2-S-D-A-K-TR is commonly used in FPGA mezzanine card stacking, high-speed digital backplanes, and compact server blade interconnects where 62 signal lines must be routed at 1.27 mm pitch. Its gold-plated contacts and high-reliability socket strip construction are also appropriate for test and measurement sockets and aerospace computing modules requiring consistent low-resistance mating over thousands of insertion cycles.

Frequently Asked Questions
How many contacts does the SFM-131-T2-S-D-A-K-TR carry and what is the contact spacing?
The SFM-131-T2-S-D-A-K-TR carries 62 contacts arranged in 2 rows at a 0.050" (1.27 mm) pitch. This high-density configuration delivers a large number of signal lanes within a compact connector footprint, making it a practical choice for FPGA daughter cards and compact module-to-module interfaces.
What advantage does the gold contact finish (K option) provide for the SFM-131-T2-S-D-A-K-TR in high-cycle applications?
The gold-plated K-option contacts maintain low and stable contact resistance across repeated mating cycles, typically rated for over 500 insertion cycles. This makes the SFM-131-T2-S-D-A-K-TR well suited for test fixtures, board-swap applications, and lab instruments where mating events are frequent and contact degradation would compromise signal integrity on 62-pin high-speed interfaces.
How does the SFM-131-T2-S-D-A-K-TR at 1.27 mm pitch compare to a 2.54 mm pitch alternative for high-density PCB layouts?
At 0.050" (1.27 mm) pitch, the SFM-131-T2-S-D-A-K-TR occupies roughly half the board area of an equivalent 2.54 mm pitch connector carrying 62 contacts, freeing approximately 30–40% more routing space on dense multilayer PCBs. This space saving is critical for compact blades and stacked modules where 62 connections must coexist with high-speed differential pairs and power planes.
