Key Features
- 34-position dual-row 1.27mm pitch socket strip with 1A per contact rating for high-density SMT board stacking
- A (action) contact design provides positive wiping action ensuring low contact resistance even after repeated 500+ mating cycles
- P polarization key prevents reverse-insertion errors, critical for dual-row connectors with 34 positions in automated assembly
Applications
The SFM-117-L2-L-D-A-P is ideal for high-density board-to-board interconnects in embedded computing modules, industrial I/O expansion cards, and medical instrumentation requiring reliable 34-signal connections. The low-mount L profile keeps stacked board separation minimal, benefiting slim portable devices and compact enclosures. Its action contact and polarized keying combination ensures consistent electrical performance across the full operating temperature range of -55°C to +125°C.

Frequently Asked Questions
What distinguishes the A (action) contact style in the SFM-117-L2-L-D-A-P from standard contacts?
The A suffix denotes SAMTEC's action contact design, which incorporates a wiping motion during mating to clear oxidation and debris from the contact surface. This wiping action maintains contact resistance below 20 milliohms across 500 or more mating cycles, significantly extending the usable life of the 34-position connector in applications that require frequent board removal and reinstallation, such as test fixtures and field-serviceable industrial modules.
How does the L (low-mount) profile of the SFM-117-L2-L-D-A-P constrain PCB stack height?
The low-mount L profile of the SFM-117-L2-L-D-A-P provides a mated stack height of approximately 2mm to 3mm depending on the complementary header selected. This is several millimeters shorter than full-mount FM variants, making the 34-position connector the preferred choice for portable devices, wearable electronics, and compact PCB assemblies where total board-to-board clearance must remain under 5mm.
For a 34-signal embedded system, when is the SFM-117-L2-L-D-A-P a better fit than a ribbon cable assembly?
The SFM-117-L2-L-D-A-P outperforms ribbon cables when vibration, mechanical stress, or EMI shielding are concerns, since the direct SMT board-to-board connection at 1.27mm pitch eliminates cable routing and reduces signal path inductance. A 34-conductor ribbon assembly can introduce several nanohenries of parasitic inductance, while the SFM connector keeps impedance tightly controlled, which is advantageous for signals switching faster than 100MHz in data acquisition and FPGA expansion applications.
