What are the key features of S1751-46R?
- Brass contact material with tin (Sn) over nickel (Ni) barrier finish for corrosion resistance and reliable probe contact
- Lead-free JESD-609 e3 compliant construction for RoHS-compatible PCB assemblies
- Designed for in-circuit test (ICT) and flying probe test applications on PCBs
- Compact test point form factor for dense PCB layouts where probe access is required
- Compatible with standard ICT probe tips and test fixture needle contacts
What is S1751-46R used for?
The S1751-46R test point is used on PCBs to provide reliable mechanical probe access for in-circuit testing (ICT), flying probe machines, and manual measurement with multimeter probes. Its brass body with tin-nickel contact finish ensures low-contact-resistance connections over many probe cycles, making it ideal for production test fixtures in consumer electronics, industrial control boards, and telecommunications equipment. It also serves as a convenient node for debugging voltage rails and signal integrity during board bring-up.

Frequently Asked Questions
What materials are used in the S1751-46R test point construction?
The S1751-46R test point uses a brass body and insulator with a tin (Sn) over nickel (Ni) barrier contact finish on the termination side. This combination provides good corrosion resistance, low contact resistance, and durability over repeated probe cycles, making it reliable for ICT and flying probe test applications.
How does the S1751-46R support in-circuit testing on high-density PCBs?
The S1751-46R provides a dedicated probe target on the PCB surface that is compatible with standard ICT needle probes and flying probe machines. Its compact footprint allows placement at signal nodes with minimal board space impact, enabling bed-of-nails and automated test fixture access to critical nets at test points across the board layout.
Is the Harwin S1751-46R compliant with lead-free assembly requirements?
Yes, the S1751-46R is lead-free and carries a JESD-609 e3 rating, confirming compatibility with RoHS-compliant lead-free solder processes. The tin-nickel contact finish is applied without lead content, making the component suitable for modern PCB assemblies that must meet global environmental regulations.
