Key Features
- 20-position single-row through-hole socket with 2.54 mm (0.100") pitch for standard breadboard and PCB header compatibility
- Gold (30 µin) over nickel (50 µin) contact finish on mating surface with beryllium copper contacts for superior conductivity and corrosion resistance
- Low-profile body design with straight solder termination, simplifying hand-soldering and wave-soldering assembly in production environments
Applications
The SL-120-T-12 is ideal for single-board computers, Arduino shields, and embedded development boards that use standard 2.54 mm pitch pin headers. Its low-profile socket design makes it a reliable choice for industrial control panels, test fixtures, and prototyping applications where frequent module swapping and secure electrical contact are required. The through-hole solder termination ensures mechanical robustness in demanding environments such as motor drives and automation equipment.

Frequently Asked Questions
What contact finish does the SL-120-T-12 use and how does it affect reliability?
The SL-120-T-12 uses a gold (30 µin) over nickel (50 µin) contact finish on the mating surface, providing excellent resistance to oxidation and low contact resistance over thousands of mating cycles. Beryllium copper contacts deliver superior spring force, making this socket reliable in industrial and instrumentation applications requiring consistent 2.54 mm pitch connections.
Can the SL-120-T-12 be used as a replaceable socket for Arduino or Raspberry Pi shield connectors?
Yes, the SL-120-T-12 is a 20-position, 2.54 mm pitch straight through-hole socket, which is fully compatible with standard 0.100" pitch headers used on Arduino, Raspberry Pi, and similar development boards. Its low-profile body allows stacking of shields or daughtercards without adding excessive height above the main PCB.
What is the recommended soldering method for the SL-120-T-12 and what pitch is supported?
The SL-120-T-12 supports both hand-soldering and wave-soldering via its through-hole straight solder termination on a 2.54 mm (0.100") pitch. The tin-over-nickel termination finish ensures good solder wettability during reflow or wave processes. This makes it well-suited for high-throughput PCB assembly lines producing embedded control modules and industrial interface cards.
