SYSTEMS AND SOLUTIONS FOR THE ENERGY TRANSFORMATION INDUSTRY

Safety interlocks are security devices that applied to two or more mobile parts prevent or allow the movement of one when the others are locked in a predetermined position.

This way only predetermined sequences allowing for making the protection of personnel and facilities, safeguarding against the risk of accidents or wrong manoeuvres

FEATURES

Locks made of easy machining materials such as brass and stainless steel, both high quality AISI 303 and 304.
Under the rules of RohS.
