DESCRIPTION

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. Voltage output and indicator light, the dual indication modes ensure its output accuracy. The compact, antenna free design allows TMR7903-B possessing excellent immunity to external EM interference performance and easy to installation.
