What are the key features of SFM-146-L2-L-D-A-P-TR?
- 92-position dual-row layout on 1.27 mm (0.050 inch) pitch achieves high signal density within a minimal PCB footprint
- High-reliability socket strip construction withstands hundreds of mating cycles for applications requiring frequent module swaps
- Tape-and-reel (-TR) packaging supports automated SMT pick-and-place assembly in high-volume production environments
- Dual-row (D) configuration routes 46 signals per row, enabling wide parallel bus or mixed signal-and-power connectivity
What is SFM-146-L2-L-D-A-P-TR used for?
The SFM-146-L2-L-D-A-P-TR is well suited for high-cycle-life board-to-board connections in aerospace avionics, defense electronics, and ruggedized industrial modules where 92 parallel signals must pass between PCBs in a compact 1.27 mm pitch footprint. Fine-pitch SMT mounting minimizes interconnect board area, making it practical for dense multi-board stacks in radar, communications, and test systems. Tape-and-reel packaging supports volume production on automated assembly lines without manual component handling.

Frequently Asked Questions
What pitch and position count does the SFM-146-L2-L-D-A-P-TR provide for board-to-board connections?
The SFM-146-L2-L-D-A-P-TR offers 92 positions arranged in 2 rows on a 1.27 mm (0.050 inch) pitch, delivering 46 signals per row. This fine pitch enables connection of wide parallel buses — such as a 32-bit data bus plus address and control lines — within a footprint roughly half the area required by standard 2.54 mm pitch connectors.
Which industries and applications specifically benefit from the high-reliability construction of the SFM-146-L2-L-D-A-P-TR?
High-reliability socket strips like the SFM-146-L2-L-D-A-P-TR are designed for aerospace avionics, defense communications hardware, and industrial instrumentation where connectors must maintain consistent electrical performance across temperature ranges of at least -55°C to +125°C and hundreds of mating cycles without measurable contact degradation.
How does tape-and-reel packaging help with SFM-146-L2-L-D-A-P-TR production assembly?
The -TR suffix denotes tape-and-reel packaging, which keeps all 92 contacts in a protected carrier tape compatible with standard SMT pick-and-place machines. This eliminates manual placement errors on the fine 1.27 mm pitch, supports placement rates of hundreds of components per hour, and reduces setup time compared to tray packaging for high-volume connector assembly.
When is SFM-146-L2-L-D-A-P-TR preferred over a standard 2.54 mm pitch socket strip of the same pin count?
The 1.27 mm pitch of the SFM-146-L2-L-D-A-P-TR reduces the connector footprint by approximately 75% compared to a 92-position 2.54 mm pitch alternative. For designs where PCB area is constrained — such as plug-in mezzanine cards or compact industrial I/O modules — the fine-pitch SFM series allows the same 92-signal connectivity in a body length under 60 mm, versus over 115 mm for the 2.54 mm equivalent.
