Frequently Asked Questions
How many mating cycles can the Tiger Eye contacts in SFM-120-02-S-D-K-TR withstand compared to standard socket contacts?
The Tiger Eye contact design in SFM-120-02-S-D-K-TR is engineered for high cycle counts, typically rated above 100 mating cycles under standard contact force. Combined with 30 µin gold plating on the mating contact surface, the connector maintains low contact resistance throughout its service life, making it suitable for modular boards that are frequently swapped or upgraded.
Can SFM-120-02-S-D-K-TR mate with standard 0.050 inch pitch pin header assemblies from other manufacturers?
SFM-120-02-S-D-K-TR uses the industry-standard 0.050 inch (1.27 mm) pitch, which is compatible with many dual-row pin headers offering the same 40-position, 0.050 inch pitch footprint. The Tin/Nickel termination and gold mating surfaces ensure reliable signal paths at 2-row, 40-pin interfaces used across telecom, computing, and test-and-measurement systems.
What is the lead time and reel packaging format for SFM-120-02-S-D-K-TR in production quantities?
SFM-120-02-S-D-K-TR has a factory lead time of 2 weeks, which is short relative to specialty connectors and supports production scheduling. The TR suffix indicates tape-and-reel packaging, enabling automated pick-and-place assembly for high-volume SMT manufacturing with standard 40-position socket strip footprint requirements.
How does the 0.050 inch pitch of SFM-120-02-S-D-K-TR benefit board-level miniaturization versus 0.100 inch pitch connectors?
At 0.050 inch (1.27 mm) pitch versus the legacy 0.100 inch (2.54 mm) pitch, SFM-120-02-S-D-K-TR reduces the connector footprint by roughly 50% per row, allowing 40 positions in a body length of approximately 1.015 inches. This density advantage is critical for compact mezzanine cards, FPGA daughter boards, and memory modules where PCB real estate is constrained.
