Key Features
- Tiger Eye contact design provides superior wiping action and gas-tight gold-on-gold mating for reliable signal integrity on 10 positions at 2.00 mm pitch
- Gold (Au) contact finish on termination side resists corrosion and supports long mating-cycle life, making it suitable for field-serviceable assemblies
- Compact body (0.407" × 0.21" × 0.178") allows tight board-stacking arrangements where standard 2.54 mm pitch connectors would not fit
Applications
The S2M-105-01-S-D is designed for board-stacking and wire-to-board applications in compact electronic assemblies such as industrial sensor modules, medical monitoring devices, and embedded computing daughtercards. Its Tiger Eye contact geometry ensures reliable electrical connection even after repeated mating cycles, making it well suited for instruments that undergo regular field servicing. The 2.00 mm pitch and dual-row layout allow 10 signals to be routed in a small PCB footprint compared with traditional 2.54 mm alternatives.

Frequently Asked Questions
What makes the Tiger Eye contact geometry of S2M-105-01-S-D distinct from standard socket contacts?
The Tiger Eye contact design uses a dual-beam wiping geometry that provides a gas-tight gold-to-gold interface with each mating cycle. This produces lower and more consistent contact resistance, typically below 20 mΩ, compared with single-beam alternatives, and sustains reliable performance over hundreds of mating cycles at 2.00 mm pitch.
How many positions does S2M-105-01-S-D carry and what physical dimensions define its PCB footprint?
The S2M-105-01-S-D carries 10 positions in a dual-row arrangement at 2.00 mm pitch. Its body measures 0.407" long × 0.21" wide × 0.178" deep, making it a compact choice for board-stacking designs where a 2.54 mm pitch connector would exceed available board area.
For a portable medical monitor design cycling connectors 200 times per year, how does the gold finish on S2M-105-01-S-D affect long-term reliability?
The gold (Au) contact finish on the S2M-105-01-S-D termination side provides excellent corrosion resistance and maintains low contact resistance across high mating-cycle counts. Gold-plated contacts are typically rated for 500 or more mating cycles, so at 200 cycles per year the connector should remain reliable for at least 2 to 3 years of active field use.
What board-stacking height options are available when pairing S2M-105-01-S-D with a compatible SAMTEC male header?
When mated with SAMTEC S2M-series or compatible male header pins, the S2M-105-01-S-D supports board-stacking heights that vary with pin length selection, typically from 4 mm to over 20 mm. Designers can choose post lengths in 1 mm or 2 mm increments to set the precise inter-board standoff required by their mechanical envelope.
