IR SF6 Monitor for Very High Voltages

IR SF6 Monitor for Very High Voltages

Infrared (IR) Sensor Module is a distance proximity sensor "switch".. When there is an object or obstacles that are close enough to block the view in front of 2 LEDs, it triggers the infrared trans-receiver module. The clear LED is the IR emitter while the black LED is the IR receiver.
