Benefits of Alfred
Rated for Explosive Environments
Third party certified to guarantee the highest level of safety. Rated for use within ATEX, IECEx and HazLoc environments.
Highly Configurable
A selection of actuators, head modules, and key adaptors which can all be mounted on an ex rated interlock.
Enforce Sequences
Enforce a predetermined sequence of events according to the application requirements. Robust lock protection.
Unexpected Start-Up Prevention
Protect operators with personnel keys as proactive inhibit functions. It is possible to include up to three trapped key adaptors.
Mechanical Only Solutions
Keep all wiring outside the explosive atmosphere and hazardous location. Suitable for Zone 0 / 20, or Division 1.
Electromechanical Solutions
Interlocks with or without guard locking to control access to machinery, suitable for Zone 1 / 21, or Division 2.

Alfred Features
Bolt Modules
Mechanical or electromechanical options. Alternative bolt lengths and number of locks available. Electromechanical variants are available with monitoring circuit or solenoid locking.
Guard Locking Function
For run-down times. Available in both Power-To-Unlock and Power-To-Lock versions. Interlocks without guard locking are also available for access to machines with no run-down times.
Escape Release
Escape release options (variable length) to allow personnel to leave the safeguarded space should they become trapped.
Stainless Steel Interlocks
Made of 316 stainless steel and with a retention force of 7kN, Alfred products are extremely robust and perfect for harsh environments and explosive atmospheres.
Heads and Actuators
A selection of five actuators for hinged and sliding guards. Market-leading misalignment capabilities to cope with guards’ movement and variability in machine guarding installation.
Intermediate Transfer
Key exchange devices (mechanical or electromechanical) for use in trapped key systems. Electromechanical variants are available with monitoring circuit or solenoid locking.
