Force Guided: Different from normal relays
Force guided relays are used in safety circuits in combination with light curtains, interlock switches, and emergency stop switches to control outputs. These are used to expand outputs for safety relay modules and safety controllers. Our force guided relays are highly engineered for reliably switching low loads by the monitoring circuit. We developed comprehensive documentation for forced guided relays to accelerate the development process for safety controls and application notes to point out possible error sources.
Force guided relays are designed to make it impossible for all circuits to be closed at the same time. Force guided relays are electromechanical switching devices that provide a safe monitoring of contacts within circuits. The force guided relay design is completely different from a conventional control relay. In a force guided relay, the armature is moved to the tip of the contact reeds and as close to the contacts as possible, which allows the contacts to move together. The contacts are each enclosed in a well inside the plastic, which contains the reed if it breaks. It also helps contain any debris created by heavily loaded contacts. These have at least one normally open (NO) contact set and one normally closed (NC) contact set. If a NO contact fails when it’s trying to open, the associated NC contact is unable to close properly when the power supply is switched off. These relays offer a cost and space-saving alternative to contactors. Force guided relays are used in safety circuits in combination with light curtains, interlock switches, and emergency stop switches to control outputs. These may be used to expand outputs for safety relay modules and safety controllers.
Safety is paramount in every corner of our daily lives. Safety in human machine interaction has one goal, protecting humans in event of a failure of the operating application. See more here about our Force Guided Relay products.
