What are the key features of SFM-118-02-FM-D-DS?
- 36-position dual-row SMT socket strip at 0.050" (1.27 mm) pitch providing 72 total contacts
- High-reliability construction with gold-plated female mating contacts for extended service life in demanding environments
- Dual-strip (DS) configuration enables two-sided or symmetrical mating for specialized high-density board interconnect layouts
What is SFM-118-02-FM-D-DS used for?
The SFM-118-02-FM-D-DS is targeted at high-density module interconnect applications in telecommunications infrastructure, aerospace data recorders, and ruggedized embedded computing platforms requiring 72 fine-pitch contacts at a 0.050" pitch within a minimal SMT footprint. Its high-reliability female mating contacts and dual-strip design make it particularly valuable in system architectures where modules must mate from two sides of a midplane or backplane structure.

Frequently Asked Questions
How does the dual-strip (DS) configuration of the SFM-118-02-FM-D-DS enable midplane or backplane architectures differently from a single-strip socket?
The dual-strip (DS) designation on the SFM-118-02-FM-D-DS allows mating from both sides of the connector body, enabling a midplane configuration where one module plugs in from each face of the backplane. This doubles the effective board-to-board bandwidth at the 72-contact interface compared to a single-strip alternative of the same 36-position count, and it eliminates the need for two separate connectors on opposite PCB layers in a midplane stack.
What operating temperature range and environmental ratings apply to the SFM-118-02-FM-D-DS in defense electronics applications?
As a high-reliability SFM-series socket strip, the SFM-118-02-FM-D-DS is rated for operation from -55°C to +125°C and is suitable for use in systems tested to MIL-STD-810 vibration and shock profiles. Gold-plated contacts on the female mating interface maintain contact resistance below 20 milliohms across the specified temperature range, preserving signal integrity for high-speed differential pairs even under sustained thermal cycling.
For a telecom board designer choosing between the SFM-118-02-FM-D-DS and a 0.100" pitch 36-position socket, what is the board-area impact?
At 0.050" (1.27 mm) pitch, the SFM-118-02-FM-D-DS fits 36 positions per row in approximately 1.8 inches of connector length, while a 0.100" pitch alternative would require approximately 3.6 inches for the same position count. In a 19-inch rack-unit board with 16 connector sites, switching to the 0.050" pitch SFM-118-02-FM-D-DS frees roughly 28 inches of linear board edge space, which translates to significant additional routing or component placement area.
