Frequently Asked Questions
What is the contact rating and current capacity per pin on the SDL-120-T-12 connector?
The SDL-120-T-12 features screw-machine beryllium copper contacts rated for approximately 3 amperes per pin continuous current rating, with peak transient capability to 5 amperes. The 40 individual contacts enable applications requiring 3-10 ampere total connector current across signal, power, and ground connections. The gold-over-nickel mating surface (30 microinches gold over 50 microinches nickel) ensures reliable low-resistance contact resistance below 50 milliohms per contact pair.
How does the 0.100-inch pitch SDL-120-T-12 compare to alternative connector pitches like 0.050-inch or 0.127-inch options?
The SDL-120-T-12 uses 0.100-inch (2.54 mm) pitch standard header spacing, the most prevalent industrial connector standard. This pitch accommodates 40 positions in dual-row configuration occupying approximately 2.0 x 0.5 inch footprint. Compared to 0.050-inch (1.27 mm) alternatives with higher density at similar overall size, the 0.100-inch pitch is easier to hand-assemble and troubleshoot during prototyping. The 0.127-inch (3.2 mm) metric pitch is less common and occupies more board space for equivalent pin counts.
Is the SDL-120-T-12 suitable for aerospace or automotive test environments requiring extended mating cycle life?
Yes, the SDL-120-T-12 screw-machine contact design is rated for 500+ mating cycles, meeting durability requirements for field-replaceable modules and test fixture applications in aerospace and automotive environments. The beryllium copper contact material combined with gold-over-nickel plating (30 microinches) ensures contact resistance stability across extended cycling. RoHS-compliant lead-free construction and tin-nickel termination base enable use in stringent industrial and military specification test platforms.
