Frequently Asked Questions
What is the contact pitch of the SFM-144-02-L-D-A-K-TR and how does it affect PCB layout density?
The SFM-144-02-L-D-A-K-TR uses a 0.050" (1.27 mm) pitch across 144 dual-row positions, enabling extremely high contact density on the PCB. This tight pitch reduces overall connector footprint significantly compared to 2.54 mm pitch alternatives, allowing more signals per square centimeter in space-constrained designs.
How many mating cycles can the SFM-144-02-L-D-A-K-TR withstand in a test fixture application?
SAMTEC SFM series socket strips are rated for 1000+ mating cycles with gold-plated contacts, making them suitable for production test fixtures and module sockets that undergo repeated insertions. The 144-pin dual-row design distributes mechanical stress across all contacts to extend service life.
Which SAMTEC mating connector is compatible with the SFM-144-02-L-D-A-K-TR for a board-to-board stack?
The SFM-144-02-L-D-A-K-TR mates with SAMTEC's SSM or TSM series vertical headers of equivalent 0.050" (1.27 mm) pitch and 144-position dual-row configuration. Selecting the correct stack height variant (e.g., 02 = 0.200" above board) allows designers to achieve the required board separation distance in 2-board stacking assemblies.
