How Do I Choose the Best Infrared Switch?

Infrared induction switch is an automatic control switch based on infrared induction technology. It realizes its automatic control function by sensing infrared heat emitted from the outside, and can quickly open various electrical equipment such as lamps, automatic doors, anti-theft alarms and so on.

The full name of infrared induction switch is pyroelectric infrared induction switch. Any object in nature always emits infrared radiation as long as the temperature is above absolute zero (-273 ° C). The higher the temperature of an object, the smaller the peak wavelength of infrared radiation it emits, and the greater the energy of infrared radiation. . When a person enters the sensing range,

1. Ultra-low power design, can

Infrared sensor switch is an automatic control switch based on passive infrared sensing technology. The main sensing device is the human body.

Working voltage: 160 250V (AC) Static power consumption current: less than 0.3mA

1. Do not connect with power during installation. It is strictly forbidden to short-circuit the load. Products that control fluorescent lamps and energy-saving lamps. It may take 30 to 60 seconds for the internal voltage to set up before the switch can work normally. ^[3]

2. Due to the large starting current of fluorescent lamps and energy-saving lamps, it is recommended that one switch control less than two loads.

3. Do not install the product in a place where hot air flows through, and keep it away from heating, air conditioners, refrigerators, stoves and other places where the air temperature changes are sensitive. If the control load is heating, it should be more than 1 meter.

4. There is no need to consider wiring polarity for 2-wire products without zero line and emergency control. Products with emergency control or zero line must be wired as shown in the figure (EM terminal without emergency control product is not connected)

5. When adjusting the light control illuminance and delay time knob, you should use moderate force. Excessive force will cause damage to the product.

6. There should be no screens, furniture, large bonsai or other isolation in the detection range.

7. Don't face the window directly, to prevent the hot air disturbance and people walking outside the window from causing false alarms.

8. The top-mounted infrared induction switch should not be too high from the ground, preferably about 2.5-3 meters. The wall panel switch can be installed in the original switch position and directly replaced.

9. Do not install in places with strong airflow such as doorways and air ducts.
