Interlocks get TÜV SÜD certification
02 June 2016
Fortress Interlocks has achieved TÜV SÜD European, Canadian and U.S. approval for its tGard range of interlock switches and control devices. This means they meet all the necessary requirements of the European Machinery Directive and the Nationally Recognized Testing Laboratory Program (NRTL) in North America.

tGard is a compact, metal-bodied interlock system that allows the configuration of a wide range of safety products, including electrical safety gate switches (with or without guard locking), mechanical trapped key interlocks and electrical operator controls – either as separate devices or integrated into one device.
Highly versatile, tGard includes selector switches, safety switches (solenoid and non-solenoid), personnel keys (safety keys), emergency release, push buttons, estops, indicator lamps as well a choice of operating handles for both hinged and sliding guard doors. These elements are simply selected and then assembled into a robust housing which is suitable for mounting onto machine guarding.
