Frequently Asked Questions
How many contacts does the SFM-109-L2-SM-D-A-P-TR provide, and what pitch does it use?
The SFM-109-L2-SM-D-A-P-TR provides 36 total contacts in an 18-position dual-row configuration at 0.050-inch (1.27 mm) pitch. This contact count is sufficient for interfaces carrying up to 16 signal lines plus power, ground, and auxiliary pins, making it a compact solution for sensor modules, wireless communication boards, and miniaturized embedded system interconnects.
What electrical ratings does the SFM-109-L2-SM-D-A-P-TR meet for signal and power connections?
Each of the 36 contacts is rated for 1 A continuous current, and gold plating maintains contact resistance below 20 mΩ throughout the operating temperature range of -55°C to 125°C. These ratings support mixed signal-and-power interfaces, allowing the connector to simultaneously carry low-voltage logic signals at 1.8 V to 3.3 V and moderate supply currents in compact IoT and medical device designs.
For how many mating cycles is the SFM-109-L2-SM-D-A-P-TR qualified, and what industries rely on this durability?
The SFM-109-L2-SM-D-A-P-TR is qualified for a minimum of 500 mating cycles while sustaining contact resistance below 20 mΩ. Medical device OEMs and portable test equipment manufacturers rely on this durability for field-replaceable sensor cartridges and calibration module interfaces that are disconnected and reconnected monthly or quarterly throughout a product's 5 to 10 year service life.
Can the SFM-109-L2-SM-D-A-P-TR be used in a lead-free high-volume SMT reflow process?
Yes, the SFM-109-L2-SM-D-A-P-TR features surface-mount termination and is packaged in tape-and-reel (TR) for standard automated pick-and-place equipment. It is compatible with lead-free reflow soldering at peak temperatures up to 260°C per IPC/JEDEC J-STD-020, meeting RoHS compliance requirements for consumer electronics and industrial products shipped into EU markets.
