Photoelectric Beam Sensor

Characteristics

How Active Infrared Sensor Works

The active photoelectric beam sensor consists of a Transmitter and a Receiver.  The infrared transmitter emits a beam of modulated infrared light that is directed at the infrared receiver. Active infrared sensor is a reliable method of intruder detection. Once set up they are extremely stable, with a high detection rate and low false alarm rate.

1. Keep alert when there is no obstruction

2. When there is an obstruction, an alarm is output.

Characteristics

Single/Twin/Quad Outdoor Beam Sensor

The mainly consideration of using single, double and quad photo beam sensors is the detection distance. Usually, for using indoor is no climatic factor so you can choose single beam infrared sensor. For outdoor beam sensor using, we will suggest you to choose double or quad beam sensors to fully ensure the highly reliabilities of detection distance.
