- Capacity
- 1–250 N
Compare miniature compression load buttons by mounting envelope, force range and output. Each series opens a drawing-focused engineering RFQ.

Screen family request bounds, convert force units and build a brief for drawing review. Exact dimensions, force range and thermal performance require a confirmed configuration.
Enter a measured or planned force, not mass in kg. Peak means additional compression above preload. A zeroed display does not remove physical preload. No automatic safety factor is applied.
Enter OD, height and peak incremental force, or load an illustrative example.
Conversion basis: NIST SP 811, Appendix B, footnote 23. Family data: our published request envelopes and controlled-document process. Results are a requirements screen, not a released product specification.
