JUTAI photocell sensors manufacturer, we provide our customers with high-quality photocell sensors, how to install 2 pairs of infrared sensors on one project same site? and make sure the working is normal and stable. so it doesn’t cause interference problems of near each other sensors. please check the video, 2 receivers and 2 transmitters, that use one power supply, 12-volt photocell.

Jutai photocell sensors work with all kinds of the automatic gate or door controllers, such as the sliding gates, swing gates or roller gates. The photocell safety photo beam sensor usually used as a safety device for automatic gates controlling. The photoelectric beam sensors have transmitter and receiver for each, as that an object is detected when the light beam is blocked from getting to the receiver from the transmitter. IR-20M single beam photoelectric detector is composed of two parts, the transmitting and receiving devices. The photoelectric infrared detector's transmitter drives the infrared and emitting a modulated infrared beam and place an infrared receiver at a certain distance. The photoelectric beam sensor's receiver receives the infrared radiation energy through the phototransistor and finally converts into an electrical signal. After proper processing, this electrical signal is then sent to the alarm controller circuit.
