TMR7903-B - MultiDimension

TMR7903-B AC Voltage Switch Sensor

TMR7903-B is an AC voltage switch sensor based on the principle of electric field differential gradient. This sensor enables the detection of AC, pulsed and other irregular electric field signals with excellent galvanic separation performance by comparing whether the voltage of the cable under test is higher than the sensor threshold voltage.
