Applications
The SSM-112-L-SV is designed for surface-mount socket applications in embedded systems, industrial I/O boards, and test fixtures where a single-row 0.100-inch pitch receptacle must mate reliably with a standard pin header across many insertion cycles. The Tiger Claw ELP contact system provides superior retention and lower contact resistance than standard single-beam socket contacts, making the SSM-112-L-SV well suited for daughter card interfaces, breakout boards, and modular system architectures. Its RoHS-compliant gold mating finish supports high-reliability signal connections in environments where oxidation resistance is required.

Frequently Asked Questions
What is the Tiger Claw (ELP) contact on the SSM-112-L-SV, and how does it improve mating retention compared to standard socket contacts?
The Tiger Claw ELP (Enhanced Leadless Package) contact on the SSM-112-L-SV uses a dual-beam clamping design that wraps around the mating pin on two sides instead of one, delivering significantly higher retention force than a single-beam socket. This design also provides a self-wiping action that clears surface oxides on the 0.100 inch pitch mating pin, maintaining contact resistance below typical limits across hundreds of mating cycles and improving long-term reliability in field-serviceable applications.
What contact finish does the SSM-112-L-SV use on the mating surface, and why does gold plating matter for low-current signal connections?
The SSM-112-L-SV uses 10 µin (microinch) gold on the mating contacts with a nickel barrier beneath the tin termination finish. Gold plating at 10 µin provides a stable, oxide-free mating surface that maintains very low and consistent contact resistance, typically below 20 milliohms, for low-current signal connections where even small resistance variations can affect measurement accuracy or signal integrity in data acquisition and test systems.
For a modular embedded system design, how many contacts does the SSM-112-L-SV provide and what header series mates with it?
The SSM-112-L-SV provides 24 contacts in a single-row configuration on 0.100 inch (2.54 mm) pitch with a body length of 1.2 inch. It mates with SAMTEC's TSW, TSM, and compatible standard 0.100 inch pitch square-pin headers from the broad industry ecosystem. The 24-position count covers typical microcontroller I/O expansion interfaces, breakout daughter cards, and modular sensor boards that require a single-row connector rather than a dual-row header.
Is SSM-112-L-SV suitable as a higher-reliability alternative to standard SIP socket strips for prototyping boards subject to frequent module changes?
Yes, the Tiger Claw ELP contact in the SSM-112-L-SV delivers higher retention force and lower contact resistance than typical single-beam SIP socket strips commonly used on prototyping boards, making it a better choice when daughter modules are swapped dozens or hundreds of times. The 10 µin gold mating finish resists fretting corrosion better than tin-only contacts, extending the connector's reliable service life well beyond 200 mating cycles on a 0.100 inch pitch single-row interface.
