Overall including modeled controls and recessed rear screws: 81.4 × 128 × 29.4 mm (width × height × depth).
23.2 SR1 adds mechanical switch retention following version 26’s split-cage and removable-clamp principle. Version 26 itself is unchanged and was not requalified. This is a partial engineering revision; the handoff identifies remaining work.
4-page overview with technical appendices. The ZIP includes the same PDF and matching files.
Materials and process
304 stainless front and rear shells with 1.0 mm nominal skins, blind internal fastening bosses, black stainless grille, PA12 carrier and a flush polymer RF window on the upper back. CNC first article proposed; threads, finish, bonds and RF performance require supplier qualification.

Original build scope
What to build first
Review the current SR1 geometry and listed unresolved interfaces. No complete print kit is released by this revision.
Confirm before the affected stage
- Before functional build 1
- Measure actual switch free play, gap, travel, return and long-PTT centre/end actuation across manufacturing tolerances. The nominal 0.65 mm stop is not a certified switch overtravel limit.Mechanical / electrical / supplier
- Before functional build 2
- Qualify M2 pilot preparation, thread engagement, torque, driver access, screw pull-out and keeper strength in the selected material.Mechanical / electrical / supplier
- Before functional build 3
- Complete physical assembly with the actual harness; qualify electrical, acoustic, optical, RF, thermal, sealing and durability performance.Mechanical / electrical / supplier
- Before functional build 4
- Complete inherited system work: 21.2B has no fully verified PCB/battery/harness layout; 23.2 retains unqualified diaphragm, PCB support, closure and USB assumptions; 5.2 retains its calibration and broader qualification requirements.Mechanical / electrical / supplier
