Key Features
- 34-position dual-row SMT socket at 1.27 mm pitch enables dense 34-signal board-to-board connections in under 22 mm mating length
- Low-profile (LM) mating height reduces total stacked PCB assembly height compared to standard-profile SFM variants
- Polarization key prevents incorrect board orientation during assembly, reducing rework risk in 34-pin mating operations
Applications
The SFM-117-02-LM-D-A-P-TR is used in thin stacked PCB assemblies such as camera modules, wearable device electronics, and compact industrial sensors where low mating height and 34 signal lines at 1.27 mm pitch are required. The keyed alignment feature ensures error-free mating during field installation and automated assembly processes.

Frequently Asked Questions
What benefit does the low-profile mating height of SFM-117-02-LM-D-A-P-TR provide in stacked PCB designs?
The LM (low-mating) height option reduces the board-to-board standoff distance by approximately 1 mm to 2 mm compared to standard SFM connectors, allowing tighter PCB stack-ups suitable for products with total assembly thickness constraints under 10 mm. This is critical in wearables and compact industrial modules where vertical space is strictly limited.
How many signal paths does SFM-117-02-LM-D-A-P-TR provide, and what current can each carry?
The connector provides 34 positions in a dual-row layout at 1.27 mm pitch, with each contact rated at 1 A. This allows the designer to allocate lines between data bus signals, I2C or SPI control lines, and 1 A power rails across the same 34-pin interface without needing an additional power connector.
In which scenario is SFM-117-02-LM-D-A-P-TR preferred over a 34-pin flat-flex cable assembly?
When rigid PCB-to-PCB alignment must be maintained with sub-0.1 mm repeatability and the assembly faces repeated mating and unmating over at least 200 insertion cycles, the SFM-117-02-LM-D-A-P-TR's gold-plated socket contacts outperform flat-flex connections that degrade after fewer cycles. The 1.27 mm pitch socket also offers lower contact resistance below 20 milliohms, improving signal integrity on high-speed differential pairs.
