Introduction

For the electric connection and safety of our heating elements, special materials are needed. In this chapter you can find suitable leads and sleeves. The connection technology in areas with more than 100°C permanent temperature should use suitable connectors and terminations. All listed leads, sleeves, terminations and connectors normally are in stock or can be supplied at short notice. We have listed only the most popular articles, should you need anything else, please do not hesitate to contact us.
