Memory Ring Selection
Users generally follow these steps when selecting memory rings:
1. Select the cable based on the signal line's capacity and number of cores;
2. Select the electrical connector based on the number of cable core wires;3. Select the connector's end fitting based on the connector model and cable size;
4. Select the corresponding memory ring model based on the end fitting's outlet size;
5. When selecting a US standard memory ring, select series A or B based on the thickness of the wave protection cover;
6. Select whether to include an insulation layer based on the user's assembly heating method or usage habits. Add a suffix if an insulation layer is included;
1; No suffix is added if there is no insulation layer. Example:
TR-04 is a domestic standard series memory ring, TR-04, without an insulation layer;
TR-041 is a domestic standard series memory ring, TR-04, with an insulation layer;
TR-04A is a US standard series A memory ring, TR-04A, without an insulation layer;
TR-04AI is a US standard series A memory ring, TR-04A, with an insulation layer;TR-04B is a US standard series B memory ring, TR-04B, without an insulation layer; TR04BI is a US standard series B memory ring, TR-04B, with an insulation layer;
Step Explanation
Standard Size D1: Represents the inner diameter before the memory ring shrinks; D: Represents the outer diameter of the connector's end fitting; D2: Represents the inner diameter after the memory ring shrinks under no-load heating; : Represents the inner surface with an insulation coating
