Key Features
- 70-position dual-row through-hole layout with 1.27mm x 2.54mm pitch delivers high contact density in a 1.75-inch body length, suitable for micro-pin IC socket and board interconnect applications
- 30 microinch gold over 50 microinch nickel mating contact finish rated for over 500 mating cycles provides long-term low-resistance connections ideal for test fixtures and prototype boards
- Tiger Buy contact technology from SAMTEC ensures consistent wipe action and contact normal force for reliable pin engagement in automated test equipment and plug-in module sockets
Applications
The SMS-135-01-S-D is used in PCB socket and board interconnect applications where a high-density 70-pin through-hole micro socket at 1.27mm x 2.54mm pitch is required, such as in IC evaluation boards, prototyping systems, and test fixtures. Its gold-plated contacts and Tiger Buy technology make it well suited for automated test equipment (ATE) sockets where repeated insertion and extraction of modules must maintain reliable electrical contact. It also serves in military and aerospace avionics systems where robustness and long mating life are essential.

Frequently Asked Questions
What are the pin pitch dimensions of the SMS-135-01-S-D, and how does the dual-row layout affect board footprint?
The SMS-135-01-S-D uses a 1.27mm (0.050 inch) pitch in one axis and 2.54mm (0.100 inch) pitch in the other for its dual-row through-hole layout. The 70-position body spans 1.75 inches in length, providing a compact but high-density footprint suitable for micro socket and test board applications where pin count must be maximized in limited PCB area.
What contact gold plating thickness does the SMS-135-01-S-D use, and how does this compare to standard connector finishes?
The SMS-135-01-S-D applies 30 microinches of gold over 50 microinches of nickel on its mating contact surfaces. This is a thicker gold deposit than the typical 10 to 15 microinches found on standard commercial connectors, providing enhanced wear resistance and lower contact resistance over extended mating cycles in test fixtures and prototype sockets.
Which automated test equipment applications benefit most from the SMS-135-01-S-D's Tiger Buy contact technology?
Tiger Buy contacts in the SMS-135-01-S-D generate consistent wipe action and controlled contact normal force during pin insertion, ensuring reliable electrical contact with gold or tin-plated pins across thousands of insertions. This makes the SMS-135-01-S-D particularly valuable in ATE handler sockets, boundary-scan test adapters, and in-circuit test fixtures where pin contact reliability directly affects test yield and false failure rates.
How does the through-hole mounting of the SMS-135-01-S-D compare to SMT socket alternatives for high-vibration environments?
Through-hole mounting of the SMS-135-01-S-D provides mechanical anchor strength significantly greater than SMT pads alone, as solder fills the barrel of each of the 70 pins, creating a robust mechanical joint that resists pull-out and vibration-induced fatigue. In high-vibration environments such as avionics, military vehicles, and industrial machinery, through-hole connectors typically exhibit 5x to 10x higher vibration resistance than equivalent SMT connectors.
