Key Features
- 70 positions in a dual-row through-hole layout with 0.050" x 0.100" pitch for high-density signal routing
- Gold over nickel contact finish (20 µin Au over 50 µin Ni) providing robust mating reliability and corrosion resistance
- 1.75 inch body length in a compact 0.22 inch x 0.335 inch cross-section for space-constrained PCB designs
Applications
The SMS-135-01-G-D is used in high-density backplane and daughtercard interconnect assemblies where 70 signals must be routed through a compact 0.050" x 0.100" pitch socket. It is well suited for test-and-measurement equipment, embedded computing modules, and industrial control boards that require reliable through-hole mating with gold-plated contacts. The socket also supports prototyping applications where removable module connections are needed without sacrificing signal integrity.

Frequently Asked Questions
How many positions and what pitch does the SMS-135-01-G-D support?
The SMS-135-01-G-D is a 70-position dual-row through-hole socket with a 0.050" x 0.100" pitch, enabling high-density signal interconnection in compact PCB layouts for embedded computing and instrumentation applications.
For a test fixture requiring 70 removable signal connections, how does the gold contact finish on SMS-135-01-G-D ensure long service life?
The contacts are finished with 20 µin gold over 50 µin nickel, providing excellent corrosion resistance and low contact resistance across thousands of mating cycles, making the SMS-135-01-G-D suitable for test fixtures with repeated insertion and removal.
What are the body dimensions of SMS-135-01-G-D and how do they affect PCB routing?
The SMS-135-01-G-D has a 1.75 inch body length, 0.22 inch breadth, and 0.335 inch depth. Its compact cross-section allows tight PCB routing even in space-constrained backplane designs, and the through-hole mounting style provides strong mechanical retention.
When would SMS-135-01-G-D be a better choice than a surface-mount connector for a backplane application?
Through-hole connectors like the SMS-135-01-G-D provide significantly higher pull-out force than surface-mount alternatives, making them preferable in backplane assemblies subject to mechanical stress during repeated card insertions, vibration environments, or when handling 70 signals at 0.100" pitch row spacing.
