The switching is done via two modern, contactless Hall sensors that respond to a magnetic field, thereby activating the electronic switches in the PowerBox. These Hall sensors do not switch the power themselves but only transmit the switching impulse. The MagSensor is an option for all PowerBox systems that were previously switched using the SensorSwitch. The MagSensor can be used to turn on and off the two circuits and to reset the capacity display in newer systems. Programming of servos or adjustments in the PowerBox menu will still be carried out with the SensorSwitch. With the MagSensor, especially scale pilots have the opportunity to operate our redundant battery switch system with a non-visible built-in on/off switch. The included ring magnet is strong enough to securely penetrate several millimeters of fiberglass/carbon fiber walls. For visual confirmation, the MagSensor features two green LEDs and also includes a piezo buzzer that accompanies the on or off process with two different tones. With the MagSensor, as with the SensorSwitch, each of the two circuits is activated individually. This also allows you to check each of these PowerBox circuits separately, even with the MagSensor. For the PowerBox Royal SRS and Champion SRS, the MagSensor is offered with a black connector.
