Potting Instructions for MPX Plug/Socket with 5-Minute Epoxy
Purpose
Mechanical strain relief for solder joints and defined strain relief through epoxy potting in a PETG mold.
Materials
- MPX plug, pre-soldered
- 3D printed PETG mold
- PTFE dry spray as release agent
- 5-minute epoxy
- M4 screws and washers
- Heat shrink tubing
- Mixing nozzle or syringe
Preparation
- Slide heat shrink tubing over the cables beforehand.
- Position tubing so it will partially lie within the potting area later.
- Shrink the tubing.
- Lightly coat the inside of the mold with PTFE dry spray.
- Wipe off excess. No visible film.
- Insert the MPX plug into the mold.
- Align cables without tension.
Closing the mold
- Join the mold halves.
- Screw together evenly with M4 screws.
- No distortion of the mold.
Potting
- Mix epoxy according to manufacturer's instructions.
- First, intentionally inject a small amount of epoxy under the contacts.
Purpose: To prevent air inclusions in the contact area. - Then slowly fill in the remaining epoxy.
- Ensure that the heat shrink tubing is completely wetted and potted.
- Gently tap or vibrate to reduce air bubbles.
Curing
- Leave undisturbed until fully cured.
- Avoid heat input.
Demolding
- Loosen M4 screws.
- Carefully open the mold.
- Remove the potted connector.
Note
- The potted heat shrink tubing acts as a flexible transition zone between the cable and epoxy.
- PTFE allows clean separation of PETG and epoxy without residue.
