For a functioning system, you need not only the profile and the evaluator unit, but also a terminating plug connector, which serves as an electrical termination. A plug connector with cable constitutes the link between the profile and the evaluator unit. In addition, the ends have to be closed off with end caps. With the Contact-Optima-Profile the end caps are installed only to close off the compensation chamber. For the Quadro-Profile, you also use a flexible wire jumper in addition to these components.
