Description of system

ECO-TRONIC SPM is a connector system that was specially developed for use e.g. in refrigerators. ECO-TRONIC SPM is a panel mount application which can be inserted in the rear wall of a refrigerator. The cavity of this rear wall is filled with PU foam.. The panel mount application, which is contacted with cables, is inserted into the rear wall without any further manual work. No manual sealing is required for the panel mount application, saving valuable time and therefore reducing manufacturing costs. The molded seal prevents the PU foam from penetrating both inside the connector and through the opening in the panel mount wall. The seal has been verified under production conditions. In addition, a positive IP 67 test has been carried out.


  • Sealed pin connector with IDC termination for panel mount applications
  • Seal against PU foam in refrigerators and freezers
  • Protection class IP 67 on the cable side, when installed
  • For mating connector according to white device specification RAST 2.5
  • Coding acc. to RAST 2.5
