amGard is the ultimate range of modular safety gate switch interlocks, for heavy duty applications. Its modular construction allows easy configuration. amGard provides total electro-mechanical solutions for practically any safeguarding application up to SIL3 (EN/IEC 62061) Categpry 4 and PLe (13849-1).
By its unique design concept, amGard offers a fully integrated safety switch controlled closing and/or locking system, designed for strength and reliability in hazardous operating conditions.
The amGard system replaces all adaptations normally fitted within a guarding system. Additional arrangements like actuators/operators, catches, internal release functions, trapped key functions and deadlocks are no longer needed. All of these separate functions are or can simply be incorporated into the amGard configurations.

The basic assemblies ATSTOP, ATLOK and AMSTOP, AMLOK are only a selection of the configurations to suit basic heavy duty safety gate switch requirements. By selection of optional modules these configurations can easily be extended with the required functions.
amGard composes dual channel safety circuits to allow cross monitoring, the robust stainless steel actuator with a self-adjusting operation provides a long life cycle and reduction of down time and maintenance. Specially designed for harsh environments the amGard range is ideal for use in areas with dust, moisture,vibration and temperature changes.
amGard trapped key modules are fully interchangeable with the Fortress mGard range of trapped key interlocks.
