Overview

A completely configurable safety interlocking solution allows specification of functionality to meet the exact requirements of your application. Pushbutton controls, ethernet connectivity and trapped key options can all be combined together into a single unit – providing a cost efficient solution compared to separate devices.

Fortress amGardpro products are designed, tested and TUV approved for use in Category 4/PLe safe control systems. The robust design and high strength rating of a Fortress interlock does not require additional safety components to be mounted to the gate to meet PLe. The integration of trapped keys within the unit can restrict access or protect employees during whole body access.

For connectivity, all devices can be specified with a quick disconnect receptacle and ordered with the correct mating cable in a variety of lengths. Or if ethernet architectures are preferred, safety over ethernet protocols can be integrated by using the proNet module which supports PROFINET/PROFIsafe and EtherNet/IP CIP Safety.

When mounting to machine guarding, mounting plates can be pre-fitted to the Fortress units to reduce fixings required in installation down to two 40mm wide variants are also available to fit narrow profiles.

A Fortress representative can help configure a solution to the exact requirements of your application. Engage us to work together on a project. With the ability to incorporate control directly into the safety device separate elements of a control system can be combined into an interlock to offer an installation saving.

Network connected products provide additional reductions in cabling and control panel I/O components. Fortress’ value is in providing custom solutions that fit the exact needs of the user – this can be through specific functionality or connectivity.

These exact requirements can usually be defined by submitting a scope or having a call with one of the Fortress team. Contact us to start the process here.

If you would prefer to create and customise a robust interlock from our heavy duty range, we have a product configurator available here.
