Single Pole Conveyor Alignment Switch
IEC AFA Conveyor Belt Alignment Switch
General Operation:
The alignment switches are mounted on both sides of conveyor systems to provide a fail-safe mechanism for conveyor belts that have misaligned to the left or right.
Alignment switches are typically mounted on either side of the header and tail pulleys on all conveyors, after every 300 meters and at every tripper drive on longer conveyor belts.
Once activated, these switches interrupt the control circuits to motors driving the conveyors and other process equipment.
Contacts: 1NO/1NC
