mGard

mGard is the only range of trapped key interlocks 3rd party approved as meeting PLe and is perfect for heavy duty applications. Fortress’ mGard is suitable for useup to SIL3 (EN/IEC 62061), Category 4 and PLe
(EN/ISO 13849-1).

Trapped key interlocking is a tried and tested method of mechanically safeguarding dangerous machines and hazardous processes. Mechanical keys eliminate most of the electrical wiring associated with other types of interlocks making it cost effective to install and maintain.
