Key Features
- 8-position dual-row SMT socket at 1.27 mm (0.050") pitch delivering high-density signal interconnects in space-critical PCB designs
- Gold-plated contact finish ensuring contact resistance below 20 mΩ and reliable mating performance over thousands of insertion cycles
- High-reliability construction rated for industrial temperature ranges from -55°C to +125°C, suitable for demanding aerospace and defense applications
Applications
The SFM-104-T2-LM-D-A is used in high-reliability board-to-board socket applications within aerospace avionics, military electronics, and industrial control systems. Its 1.27 mm pitch and dual-row 8-position layout efficiently handles signal buses on compact mezzanine cards and daughter boards. The gold-plated contacts and SMT footprint support both high-frequency signal integrity and automated reflow assembly in production environments.

Frequently Asked Questions
What pitch and position count does the SFM-104-T2-LM-D-A socket strip provide?
The SFM-104-T2-LM-D-A is a dual-row socket strip with 8 total positions (4 per row) on a 1.27 mm (0.050") pitch. This compact configuration is designed for high-density mezzanine card applications where minimizing connector footprint is critical, while still providing adequate pin count for control and data signals.
Over what temperature range can the SFM-104-T2-LM-D-A reliably operate in field deployments?
The SFM-104-T2-LM-D-A is rated for operation from -55°C to +125°C, covering the full industrial and military temperature range. This makes it suitable for avionics, defense electronics, and harsh-environment industrial controls where ambient temperature swings of 180°C or more can occur between cold-soak storage and full-power operation.
How does the SFM-104-T2-LM-D-A compare to a through-hole socket strip for field-serviceable mezzanine modules?
Unlike through-hole alternatives, the SFM-104-T2-LM-D-A uses a surface-mount footprint that avoids drilling the PCB, saving board space and enabling denser component placement. However, its 1.27 mm pitch also accommodates modules that need to mate and unmate repeatedly in the field, with the gold plating maintaining low contact resistance across at least 500 mating cycles at the 0.050" pitch standard.
