Conveyor Belt Alignment Switches with ATEX Exd IIC T6 certified explosion proof contact blocks.
The switches conform to European harmonized standards EN60079-0 and EN60079-1 and can be used in European Zone 1,21,2,22 Environments (Gas and Dust). Designed especially for use in oil, petro-chemical, pharmaceutical and food processing applications where potentially explosive atmospheres are present.
Conveyor Belt Alignment switches are mounted on sections of plant conveyors to protect against excessive belt drift due to an unintentional movement. They can be fitted at appropriate points along the conveyor length to ensure that should the belt position drift, the roller arm of the switch will move to a pre-determined position and cause activation of a control circuit.
Each standard sized belt alignment switch contains two sets of contacts, one which indicates a warning signal (for maintenance purposes) and the other a stop signal, disconnecting the outputs and stopping the belt.
All switches conform to European Standard IEC 60947-5-1 and provide positively operated contacts at the point of tripping. They can be used to satisfy the requirements of EN 620 with regard to conveyor control hazards caused by shifting of the belt position during running. They are available in different roller diameters to provide heavy duty performance and long life.
