The document provides a comprehensive matrix of 3M test‑clip part numbers, showing compatible connector types, plating options, and mechanical dimensions for both through‑hole and surface‑mount styles. It also includes a logical‑connection matrix that maps test‑clip pins to cable assemblies and remote‑end terminations.
Additional sections describe the unique design of 3M surface‑mount test clips, their general features such as four‑sided opening, helical compression springs, and staggered contact rows, and highlight the benefits of gold‑plated versus alloy leads for reliable electrical contact.
| Contact pin size | .025" square pins on .050" centers |
|---|---|
| Minimum lead spacing | .050" center‑to‑center |
| Four‑sided opening | All four sides open simultaneously |
| Staggered contact rows | .100" centers for easy socket attachment |
They use industry‑standard .025" square contact pins on .050" centers.
All four sides open simultaneously, allowing one‑step secure attachment.
