Safety Switch and Trapped Key Interlock Systems
IN ADDITION to functionality and functional safety, cost can play a decisive role in the commercial competitiveness of machinery and plant.
For example, accepting fault exclusions for the sake of an apparent cost saving, involve a significant potential risk. Machine manufacturers who procure safety components with fault exclusions, should be aware that they may considered liable in the event of a fault!
For this reason Dold has developed a safety switch and key transfer system without compromise – SAFEMASTER STS. This TÜV-certified system, which is available in stainless steel and fibre reinforced polymer, is suitable for standalone use in safety applications up to category 4 / PLe according to EN/ISO13849-1 – without any fault exclusions.
SAFEMASTER STS combines the advantage of safety switches, guard locks, trapped key transfer and command functions all in one system. The modular, expandable system has the ability to safeguard access doors without wiring therefore reducing installation, retrofitting and maintenance cost. In addition the stainless steel versions offer a solution that can withstand even the roughest environmental conditions.
