Key Features
- 46-position through-hole micro socket with 0.050 x 0.100 inch dual-row pitch for ultra-high-density layouts
- Tiger Buy contact design providing cost-effective alternative to standard precision socket contacts
- Gold (30 µin) over Nickel (50 µin) mating contact finish ensuring reliable low-resistance electrical interface
- Tin-over-nickel termination for wave solder or selective solder compatibility in through-hole assembly
- Compact 1.15-inch body length enabling miniaturized PCB footprints in space-constrained electronics
Applications
The SMS-123-01-S-D is ideal for high-density board-level interconnect in test and measurement sockets, prototype development boards, and compact industrial modules where 46 signal lines must be routed at a 0.050 x 0.100 inch pitch. The Tiger Buy contact design and gold-finished mating surface make it suitable for socketing fine-pitch headers in applications requiring repeated mating cycles, such as removable processor modules, field-replaceable sensor boards, and portable test fixtures.

Frequently Asked Questions
What pitch configuration does SMS-123-01-S-D use and how does it compare to standard 0.100 inch pitch connectors?
The SMS-123-01-S-D uses a 0.050 x 0.100 inch dual-row pitch, meaning contacts are spaced 0.050 inch within each row and 0.100 inch between rows. This halves the within-row spacing versus standard 0.100 x 0.100 inch connectors, allowing 46 positions in a body length of just 1.15 inches while maintaining compatibility with standard 0.100 inch row pitch headers.
How does the Gold (30 µin) over Nickel (50 µin) contact finish benefit the SMS-123-01-S-D in repeated-mating applications?
The 30 µin gold mating surface on 50 µin nickel barrier provides a wear-resistant, low-contact-resistance interface rated for hundreds of mate/unmate cycles. Contact resistance typically stays below 20 mΩ throughout the rated cycle life, making SMS-123-01-S-D well suited for socketed module designs, test fixtures, and removable daughter card interconnects where long service life is required.
In which board-level applications is the Tiger Buy contact feature of SMS-123-01-S-D particularly advantageous?
The Tiger Buy contact design reduces per-pin material cost while maintaining reliable spring force at 0.050 x 0.100 inch pitch. This makes SMS-123-01-S-D advantageous in cost-sensitive high-volume production of 46-position micro sockets for consumer electronics, handheld instrumentation, and embedded computing where thousands of units are assembled using wave solder through-hole processes.
