Specifies the particular characteristics of a terminal junction system (TJS), designated as type2, and meant for use at temperatures from -55 degrees C to +155 degrees C. Coverage includes definitions, designation and tooling. Also gives detailed tables and diagrams.

1.1 This part of ISO 8668 specifies the particular characteristics of a terminal junction system (TJS), designated as type 2, and intended for use at temperatures from − 55 °C to + 155 °C.

1.2 The junction system covered by this part of ISO 8668 comprises:

  1. feedback modules in four sizes;
  2. feedthrough modules in four sizes;
  3. frames adapted to these modules: monolithic frame and double frame for feedback modules, and double frame for feedthrough modules;
  4. spacers;
  5. removable male crimp contacts of sizes 22, 20, 16 and 12;
  6. sealing plugs.
