Key Features
- 66 positions at 0.050 inch pitch provides twice the signal density of standard 0.100 inch connectors in the same board length
- High-reliability socket strip construction with gold-plated contacts ensures low contact resistance and long insertion life
- Surface mount design supports automated SMT assembly, eliminating through-hole drilling in high-density PCB layouts
Applications
SFM-133-L2-L-D-A-K is used in high-density mezzanine board stacking, FPGA daughter cards, and compact embedded modules where 66 signals must be routed across two boards in a minimal footprint. The 0.050 inch pitch is particularly valued in aerospace avionics and military electronics where space and weight constraints demand maximum pin density per square centimeter. Its high-reliability socket construction withstands repeated mating cycles in test fixtures and field-replaceable module assemblies.

Frequently Asked Questions
What signal density advantage does SFM-133-L2-L-D-A-K offer compared to standard 0.100 inch connectors?
SFM-133-L2-L-D-A-K uses a 0.050 inch (1.27 mm) pitch, providing twice the signal density of standard 0.100 inch pitch connectors over the same board length. Its 66 positions in a dual-row layout fit in roughly half the PCB footprint of an equivalent 0.100 inch connector, enabling high-density mezzanine designs where board real estate is severely constrained.
For how many mating cycles is the SFM-133-L2-L-D-A-K high-reliability socket rated?
SAMTEC's SFM series high-reliability socket strips are typically rated for a minimum of 100 mating cycles, with gold-plated contacts providing stable contact resistance below 20 milliohms throughout the connector's service life. This durability suits test fixture applications where module boards are frequently inserted and removed during production testing, without degrading signal integrity on the 66-position connector.
Which mating headers mate with SFM-133-L2-L-D-A-K for a 66-position 0.050 inch pitch connection?
SFM-133-L2-L-D-A-K mates with SAMTEC's TSM or SHF series dual-row 0.050 inch pitch headers with 66 positions. The 'D' suffix in the part number denotes dual-row configuration, and mating headers must match the 0.050 inch pitch and dual-row layout to achieve proper 66-pin engagement across both rows without mechanical interference or contact misalignment.
