Key Features
- 8-position dual-row layout at 0.050" (1.27 mm) pitch delivers high-density mating in minimal PCB footprint
- Flex-mount (FM) termination style accommodates board-level flex connections with controlled contact normal force of approximately 30 g per pin
- High-reliability socket strip construction rated for 1000+ mating cycles and continuous operation from -55°C to +125°C
Applications
The SFM-104-T2-FM-D-A is suited for high-density board-to-board and board-to-flex signal interconnect in compact embedded systems, data storage modules, and medical instrumentation. Its 0.050" pitch and dual-row 8-position design allow reliable routing of 8 differential pairs or mixed signal/power channels within a small PCB area. Engineers use this socket strip in test fixtures, prototype boards, and production assemblies where repeatable 1.27 mm centerline mating is essential.

Frequently Asked Questions
What is the pin count and pitch of the SFM-104-T2-FM-D-A?
The SFM-104-T2-FM-D-A has 8 total positions arranged in a dual-row configuration with a 0.050" (1.27 mm) pitch. This compact layout provides 4 pins per row and is optimized for surface-mount assembly on boards with tight component spacing requirements.
What operating temperature range does the SFM-104-T2-FM-D-A support?
The SFM-104-T2-FM-D-A is rated for continuous operation from -55°C to +125°C, making it suitable for both commercial and industrial temperature environments. The beryllium copper alloy contacts maintain stable contact resistance below 20 mΩ across the full temperature range.
How does the flex-mount termination style on the SFM-104-T2-FM-D-A differ from standard SMT termination?
The flex-mount (FM) termination style on the SFM-104-T2-FM-D-A uses compliant leads that absorb mechanical stress during PCB flex or thermal cycling, unlike rigid SMT leads. This reduces solder joint cracking risk in applications with 100+ thermal cycles between -40°C and +85°C.
For which compact system designs is the SFM-104-T2-FM-D-A a better fit than a 2.00 mm pitch alternative?
The SFM-104-T2-FM-D-A at 1.27 mm pitch is ideal for space-constrained designs such as wearable medical devices, SSD mezzanine cards, and small-form-factor FPGAs where board real estate is limited. It can reduce connector footprint by up to 40% versus 2.00 mm pitch 8-position alternatives while supporting 1 A per contact current rating.
