What are the key features of SFM-143-T2-LM-D-A-K?
- 86-position dual-row SMT socket at 0.050" pitch for maximum pin density in compact PCB footprints
- Integrated locking mechanism (K suffix) preventing accidental unmating under shock and vibration
- Low-mount (LM) option reducing overall connector height for space-constrained board designs
- Gold-plated contacts at 1A per pin rating across -55°C to +125°C operating temperature range
What is SFM-143-T2-LM-D-A-K used for?
The SFM-143-T2-LM-D-A-K is designed for high-density board-to-board applications in industrial automation, telecommunications, and aerospace where 86 contacts at 0.050" pitch with a reduced stacking height are required. The locking retention feature makes it an excellent choice for vibration-prone environments including UAV electronics, ruggedized computing, and rail transportation systems where secure connector retention is mandatory. Its SMT low-mount configuration supports thin, lightweight PCB assemblies in space-constrained electronic enclosures.

Frequently Asked Questions
What unique combination of features does the LM suffix provide in SFM-143-T2-LM-D-A-K?
The LM (low-mount) suffix provides a reduced overall connector height compared to standard SFM variants, enabling tighter board-to-board stacking distances. At 0.050" (1.27mm) pitch with 86 positions and gold-plated contacts rated at 1A per pin, this combination is ideal for slim embedded systems and wearable industrial devices where vertical space is at a premium.
How does the SFM-143-T2-LM-D-A-K perform in environments with continuous vibration, such as industrial machinery?
The K-suffix locking mechanism on SFM-143-T2-LM-D-A-K provides positive mechanical retention that resists accidental disconnection under continuous vibration. The dual-row 86-position layout with gold-plated contacts also maintains contact resistance below specified limits across the full -55°C to +125°C thermal range, ensuring stable performance in factory floor or motor-drive enclosure environments.
Can SFM-143-T2-LM-D-A-K be used for mixed signal and power distribution across its 86 pins?
Yes, each of the 86 gold-plated contacts in SFM-143-T2-LM-D-A-K is rated at 1A per pin, allowing flexible assignment of signal lines and low-power supply rails across the dual-row footprint. Designers can dedicate multiple adjacent pins for ground and power distribution while routing high-speed differential signals on the remaining contacts.
