Inline enclosure for the popular Sonoff MiniR4 and MiniR4M relays.
Features
- Robust yet compact enclosure.
- Ample room for cable management.
- Cable tie (up to 3.5mm) mountings for flex strain relief (use 2 cable ties for thinner cables).
- Snap-in mounting for Wago 222-413 lever connector (makes it easy connect up the earth conductors).
- Secure push fit mounting for the Sonoff Mini.
- Access to the Sonoff push button.
- Snap-on top (you need a dialled in printer and profile for this to work).
- 4 screw holes for 15mm M3 cap-head screws for secure fixing of top.
- Vented and Plain tops.
- Both tops also have versions with 3D printed M3 threads or holes sized for M3 heat-set inserts (4.4mm holes).
Update - 7th Nov 2025
- Added base plate with screw mounting tabs (4mm countersunk holes).
- Added a simple cable clamp for thinner cables (sits between cable tie and cable - yellow part in last rendered image).
