Key Features
- 40-position dual-row through-hole micro socket with 0.050" x 0.100" pitch for high-density board interconnects
- Gold (30 µin) over nickel (50 µin) contact finish for reliable low-resistance mating
- 1-inch body length with 0.22-inch breadth and 0.335-inch depth for compact footprint PCB mounting
Applications
The SMS-120-02-S-D is suited for high-density board-to-board and board-to-module interconnect applications in test equipment, industrial automation, and data acquisition systems. Its 0.050" x 0.100" pitch micro socket design allows compact routing where standard 0.100" pitch connectors would consume excessive board space. The through-hole design provides mechanical robustness for applications subject to vibration or repeated mating cycles.

Frequently Asked Questions
What pitch and pin count does the SMS-120-02-S-D provide, and how does this compare to standard 0.100" pitch connectors?
The SMS-120-02-S-D offers 40 positions arranged in a dual-row configuration with a 0.050" x 0.100" pitch. This is a micro-pitch socket, meaning it achieves twice the density along the 0.050" axis compared to standard 0.100" x 0.100" connectors, making it suitable for space-constrained PCB designs requiring 40 contacts.
Which industrial or test-equipment designs benefit most from the SMS-120-02-S-D through-hole socket construction?
Applications such as data acquisition modules, industrial control backplanes, and bench test fixtures benefit from the through-hole construction of the SMS-120-02-S-D because it provides superior mechanical retention compared to surface-mount alternatives. The 1-inch body length accommodates 40 positions at 0.050" x 0.100" pitch, and gold (30 µin) over nickel (50 µin) contacts ensure low-resistance connections over thousands of mating cycles.
What is the contact finish specification of the SMS-120-02-S-D, and why does it matter for connector reliability?
The SMS-120-02-S-D uses gold (30 µin) plated over nickel (50 µin) contacts. Gold plating at 30 µin thickness provides excellent oxidation resistance and maintains contact resistance below typical 20 mΩ thresholds across more than 500 mating cycles, which is critical in high-reliability instrumentation and aerospace-adjacent test systems where intermittent contact is unacceptable.
