Installation and Wiring Diagram of Induction Switch

The sensor switch can be divided into 86-type sensor switch and ceiling-mounted sensor switch in terms of appearance.
2. The 86-type sensor switch is the same size as the traditional mechanical wall switch, and can directly replace the original wall switch.
3. The installation method of the ceiling sensor switch is similar, taking BR-306C as an example. Open a circular hole with a diameter of 60mm on the ceiling. L, N, LOUT, and NOUT are respectively connected to the incoming line of live wire, incoming line of neutral line, outgoing line of live line and outgoing line of neutral line. After connecting the wires, buckle the switch into the ceiling. If there is no suspended ceiling in the installation environment, the switch top box can be locked on the top with screws first, and then the switch can be screwed into the bottom box.

Sensor switch wiring diagram

Because the sensing range of the left and right sides of the switch is larger than that of the upper and lower sides, when installing the switch, the positive axis should be as perpendicular as possible to the direction of the person’s walking path, so as to achieve the best sensing effect.
5. After installing the switch, turn on the power. When the ambient light is sufficient, the bulb will flash three times. After one minute, the initialization ends, and the switch enters the monitoring state. Block the ambient light with an object to make the switch sense work. If the person does not leave and is active, the switch will continue to work; after the person leaves, the switch will automatically turn off the load with a delay.6. Turn on the power after installing the switch. When the ambient light is insufficient, the switch directly enters the monitoring state, and the switch will continue to work if the person does not leave and is active.7. If you are not satisfied with the delay time or light sensitivity value, you can adjust it through the “TIMER” and “DIMMER” on the back of the 86-type wall switch. Among them, the former adjusts the delay time and the latter adjusts the light sensitivity value. When adjusting, use a screwdriver to twist lightly, and do not use too much force. For the ceiling sensor switch, the adjustment potentiometer can be seen by opening the cover.

Six, induction switch circuit introduction
In this circuit, the relay releases when the metal tongue is inserted between the two winding halves, making it particularly suitable as a terminal switch. The insertion depth can be adjusted precisely to a few hundredths of a millimeter.

1. The oscillation frequency of the oscillator measured in the circuit is about 200kHz. The coil of the collector tank is wound on half of the ferrite segmented core. The base feedback coil is wound on the other half of the core. The relative distance between the two halves of the iron core is about 5mm. This space realizes the magnetic field cross-linking of the two coils.

2. The 1kΩ potentiometer on the emitter circuit generates feedback. The potentiometer should be adjusted until the oscillator just starts to vibrate.

3. Coil data: n1: 40 turns, 0.12mm copper enameled wire; n2: 75 turns, 0.12mm copper enameled wire; ferrite core: 11∮×7.

7. Wiring of sensor light switch
The use of induction lamps is becoming more and more widespread, so users need to know more about some information about induction lamps in order to carry out maintenance at ordinary times. Here is a method of wiring a sensor light switch. There are many types of sensor lights. Here we take the human body induction switch, microwave induction switch and four-wire induction switch wiring as examples.
