With its unrivalled design concept, amGardpro offers a range of fully integrated safety interlocks, including solenoid and non-solenoid safety switches complete with a host of additional options including key control modules, internal and escape release, redundant sensors, lock out/tag out and push buttons, estops and indication lights for enhanced functionality, all assembled in one device. The robust construction of this range makes it ideal for use in a wide range of industrial applications when safety, strength and reliability are of paramount importance.

The amGardpro system replaces all adaptions normally fitted within a guarding system, such that additional hardware like door catches, actuators, closing mechanisms, internal release mechanisms, key functions including authorised access and deadlocks are no longer needed. All of these separate functions can be incorporated into amGardpro configurations, resulting in the most flexible safety gate switch solution available for today's industrial environment.

It is called "Trapped Key" as it works by releasing and trapping keys in a predetermined sequence. As an example, after the control or power has been isolated on a machine, a key is released that can be used to grant access to individual or multiple doors OR after a switch disconnector has been opened in an electrical interlock scheme, a key is released to enable an earth switch to be closed and applied.

The principles of trapped key interlocking apply to all industries where it is essential that all energy sources are isolated before gaining access to machinery. Almost all safety issues can simply be solved by selecting the required products in order of the steps shown on this page.
Fortress trapped key interlocking is a tried and tested method of mechanically safeguarding dangerous machines and hazardous processes, and is suitable for use in safety applications up to SIL 3 (EN/IEC 62061), Category 4 and PLe (EN/ISO 13849-1), as approved by independent test house TUV.

tGard offers "a customised safety solution, as standard" and is defined by a range of tGard elements, including selector switches, safety switches (solenoid and non solenoid), personnel keys (safety keys), emergency release, push buttons, estops, indicator lamps and a choice of operating handles for both hinged and sliding guard doors. These elements are simply selected and then assembled into a robust housing, suitable for mounting onto machine guarding, providing the user with an exact configuration specific to the application.

tGard is quick and easy to install and can be mounted directly onto a flat surface, doors or extruded aluminium profiles without the need for mounting plates or brackets. It is IP65 as standard and has been designed to be fully compliant with the new machinery safety standards.
