Key Features
- 38-position dual-row layout on 0.050-inch (1.27 mm) pitch delivers high signal density in a compact SMT footprint for space-constrained board designs
- High-reliability contact system ensures consistent low insertion force and stable electrical performance over thousands of mating cycles in industrial and instrumentation applications
- Surface mount termination with LM (Low Mount) profile minimizes connector height above the PCB, enabling slim stackup configurations in embedded computing and test modules
Applications
The SFM-119-T2-LM-D-A-K is used in high-density board-to-board and module-to-board socket applications in embedded computing, instrumentation, and test equipment where 38 positions on a 0.050-inch pitch must fit in a compact low-mount SMT footprint. Its dual-row configuration supports mixed signal and power routing in a single connector interface. The high-reliability contact design suits medical devices, aerospace electronics, and industrial control modules requiring long service life under repeated mating.

Frequently Asked Questions
How does the 0.050-inch pitch of the SFM-119-T2-LM-D-A-K compare to standard 0.100-inch connectors for PCB density?
The SFM-119-T2-LM-D-A-K uses a 0.050-inch (1.27 mm) pitch, which is half the spacing of standard 0.100-inch connectors. This allows 38 positions to occupy approximately the same board length as a 19-position 0.100-inch strip, doubling signal density in the same footprint for high-count PCB socket applications.
What does the dual-row layout mean for signal routing on the SFM-119-T2-LM-D-A-K?
The dual-row arrangement provides 19 contacts per row across the 38 total positions, enabling designers to segregate signal types such as analog, digital, and power within a single 0.050-inch pitch connector body. This simplifies PCB routing compared to using multiple single-row connectors and reduces total board area consumed by interconnects.
Which high-reliability applications are best suited for the SFM-119-T2-LM-D-A-K socket strip?
Medical instrumentation, aerospace data acquisition boards, and industrial test modules benefit most from the SFM-119-T2-LM-D-A-K, where repeated mating of 38-position 0.050-inch pitch socket interfaces must remain reliable over thousands of insertion cycles. The surface mount low-mount (LM) profile also supports slim PCB assemblies in portable medical and avionics equipment.
Can the SFM-119-T2-LM-D-A-K be used as a module socket for daughtercard connections?
Yes, the SFM-119-T2-LM-D-A-K is designed as a high-reliability socket strip for module-to-board applications, accepting 0.050-inch pitch mating headers. Its 38-position dual-row SMT configuration supports removable daughtercard or mezzanine modules where in-field replacement or functional upgrades across 38 signal channels are required.
