According to supplier E. Dold & Söhne, Safemater STS combines the advantages of safety switches, guard locking devices, key transfer and command functions in one system. The previous stainless steel version has now been supplemented by a variant that offers a robust stainless steel mechanism in a visually appealing plastic housing. The security system has been specially designed in accordance with DIN EN ISO 13849 and is certified by TÜV. The modular system design offers users a high degree of flexibility and enables reliable protection of hazardous areas. Thanks to the ability to combine stainless steel and plastic versions, the plastic version can be used on the control panel, for example, while the highly robust stainless steel version can be used in harsh environments. The system includes both electromechanical and purely mechanical modules. Their slim design enables space-saving installation on the safety guard. Even the simplest module combinations enable the wiring-free, purely mechanical protection of safety gates up to PL e/ Cat. 4.
