Frequently Asked Questions
How many signal positions does SFM-145-L2-ZZ-D-A-K-TR provide and at what pitch?
SFM-145-L2-ZZ-D-A-K-TR provides 90 positions in a dual-row layout at 1.27 mm (0.050 inch) pitch, with 45 contacts per row. This achieves approximately twice the signal density of a comparable 2.54 mm pitch connector, making it suitable for routing 90 digital or analog channels between stacked PCBs in a compact SMT footprint.
What advantages does the ZZ contact style offer in SFM-145-L2-ZZ-D-A-K-TR over standard contact profiles?
The ZZ contact style in SFM-145-L2-ZZ-D-A-K-TR is engineered for low normal force and consistent wipe action, delivering reliable electrical contact with contact resistance typically below 20 mΩ across the rated mating cycle life of 1000+ insertions. This is advantageous in module-swap applications where the mating connector is inserted and removed repeatedly.
Is SFM-145-L2-ZZ-D-A-K-TR suitable for avionics or defense-grade PCB assemblies?
Yes, SFM-145-L2-ZZ-D-A-K-TR meets the temperature range requirement of -55°C to +125°C and uses a high-reliability contact system qualified for demanding aerospace and defense environments. Its 90-pin 1.27 mm pitch dual-row format accommodates high channel-count signal routing on avionics line replaceable units (LRUs) where PCB real estate is limited and connector reliability over thousands of mating cycles is required.
