What are the key features of SFM-114-L2-H-D-A-P-TR?
- 28 positions in a dual-row layout with 14 contacts per row for moderate-density board interfaces
- 0.050" (1.27 mm) pitch allowing tight SMT footprint in space-limited PCB designs
- Polarized (A) configuration preventing incorrect connector mating
- Gold-plated (P) contacts for low contact resistance and long-term corrosion resistance
- Tape-and-reel (TR) packaging enabling automated pick-and-place assembly
What is SFM-114-L2-H-D-A-P-TR used for?
The SFM-114-L2-H-D-A-P-TR is designed for compact board-to-board and mezzanine interconnect applications in industrial controls, embedded computing, and instrumentation systems. Its 28-position dual-row layout with polarization prevents incorrect assembly, making it suitable for keyed interface boards and sensor modules. The gold-plated contacts provide reliable conductivity across a wide temperature range, supporting long-life operation in harsh environments.

Frequently Asked Questions
What does the polarization feature of the SFM-114-L2-H-D-A-P-TR prevent during assembly?
The polarization (A suffix) mechanically restricts mating to a single correct orientation, preventing reversed insertion across all 28 contacts. This is critical in systems where incorrect polarity on signal or power pins could damage sensitive components or cause 3.3 V or 5 V rail conflicts.
Why are gold-plated contacts important in the SFM-114-L2-H-D-A-P-TR for industrial use?
Gold plating on all 28 contacts provides a contact resistance typically below 20 mΩ and resists oxidation even after prolonged exposure to humidity or temperatures up to 85°C. This ensures stable signal integrity across thousands of mating cycles in industrial sensor or control board applications.
How does the 0.050" pitch of the SFM-114-L2-H-D-A-P-TR compare to standard 0.100" pitch connectors for PCB space savings?
At 0.050" (1.27 mm) pitch, the SFM-114-L2-H-D-A-P-TR occupies roughly half the linear board space of a 0.100" pitch connector carrying the same 28 signals. A dual-row 28-position 0.050" connector measures approximately 17.8 mm in length versus 35.6 mm for an equivalent 0.100" through-hole option.
What role does the tape-and-reel packaging play in high-volume production of boards using SFM-114-L2-H-D-A-P-TR?
Tape-and-reel packaging feeds the connector directly into pick-and-place machines, reducing manual handling and enabling placement rates of hundreds of parts per hour. This packaging eliminates the need for manual tray loading, cutting per-board assembly time for 28-pin dual-row SMT connectors in batches of 1000 units or more.
