Frequently Asked Questions
What contact pad dimensions does the S70-125161545R provide, and why does this matter for PCB layout?
The S70-125161545R features a rectangular 2.50x1.60mm SMT contact pad with a 0.15mm tip thickness. This precise footprint allows designers to allocate only 4 mm² of board area per pin, making it practical for high-density layouts in wearables and handheld test interfaces.
Which assembly methods are compatible with the S70-125161545R pogo pin?
The S70-125161545R is supplied in tape-and-reel (T+R) format, making it fully compatible with standard SMT pick-and-place equipment. Its surface-mount design eliminates through-hole drilling, reducing PCB fabrication costs and supporting reflow soldering at standard 250°C peak temperatures.
In what spring-contact applications can the Harwin S70-125161545R replace a traditional press-fit pin?
The S70-125161545R is a direct replacement for press-fit pins in battery-contact interfaces, charging cradles, and test-fixture probe points that require a compliant spring force over 0.15mm travel. It is particularly effective in consumer electronics with removable modules requiring at least 5,000 mating cycles.
How does the 0.15mm tip thickness of the S70-125161545R affect electrical contact reliability?
A 0.15mm thick tip concentrates normal force on a small area, typically achieving contact resistance below 50 mΩ at rated spring compression. This ensures stable low-resistance connections in portable devices where board-to-board spacing is less than 1 mm and vibration is present.
