A range of mechanical trapped key interlocks designed to enforce processes without the need for electrical wiring. Cost-effective, easy to install and maintain, and ideal for areas difficult to reach with cables. mGard can enforce specific key sequences, particularly in applications involving multiple energy sources.

Control Hazardous Energy
Mechanical interlocking can be used to control hazardous energy sources (e.g., electrical, pneumatic, hydraulic).

Enforce Sequences
Trapped key systems can be used to enforce a predetermined sequence of events according to the application requirements.

A Cost-Effective Solution
Fully mechanical units are easy to maintain and do not require wiring, with reduced installation cost and time.

Minimise Machine Downtime
Designed for long-term durability reducing the need for repairs and maintenance. Also available in stainless steel for harsh environments.

Enhance Safety and Compliance
Used to meet the requirement of ISO 14119 and ISO 14118. Suitable for use up to PLe/Cat. 4.

Cover Vast Areas
Enforce processes across multiple levels and long distances. Fully mechanical units are ideal for areas difficult to reach with cables.
