amGardpro Family 2019-2.png

The strongest interlock switch in the world

Highest level of actuator mis-alignment on the market

TUV approved to PLe

Safety key option prevents unexpected startup

Modular design allows flexible approach to machine safety

amGardpro is the ultimate range of safety gate switches, from Fortress Interlocks. The range has a unique modular construction which allows easy configuration and provides total electro-mechanical solutions for practically any safeguarding application up to EN ISO 13849-1, Category 4, PLe (SIL3).  This range of safety component products has been 3rd party approved by TUV SUD

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.

How to Configure amGardpro Electro / Mechanical Gate Switches?


Network Connectivity with proNet
Enabling Communication with Industrial Network Protocols


A network communication module developed by Fortress that allows amGardpro to communicate with the main industrial network protocols: EtherNet/IP, PROFINET and EtherCAT.


A proNet option pod can be configured as part of an amGardpro interlock, but also as standalone control station and connected to external devices.


Standard and safety I/O are communicated through a chosen protocol via a cable connected to the Fortress proNet device. Safety I/O is exchanged using PROFIsafe, CIP safety, or Safety over EtherCAT.
