Door Positioning Sensor

Magnetic contact is used as Door Position Sensor to monitor the position of the door. The magnetic contact consists of a reed contact on Door Frame and a permanent magnet on Door Shutter. When the door is opened, the reed contact is opened as the magnet is taken away. This reed contact status is used by the Door Controller to decided if the Door is in closed position or open position. DPS is used only when Door position monitoring is included in Door Interlock system design.
