Light Magnet Contactor
In many applications we have different requirements for Light trigger, Sound detection, etc.
Light Magnet Contactor is one of the solutions. It has to work with light sensor to activate the magnetic switch.
Acousto-optic control switch: With switches controlled by sound and light, when the brightness of the environment reaches a certain set value and the ambient noise exceeds a certain value, this switch will be turned on.
Sound and light control switch must have two conditions at the same time, sound and light will work. From the structural analysis of the sound and light control switch, the surface of the switch panel is equipped with a photodiode, and a columnar body microphone is installed inside. The sensitive effect of the photodiode, only played in the dark (available digital multimeter measured value). In other words, when the color of the day dims to a certain extent, the photodiode will induce a pulse current on the electronic circuit board after induction, so that the photodiode circuit is in a closed state. At this time, as long as there is a sound at the stairway, the column pole The body microphone will also produce a pulsed current, and the acousto-optic control switch circuit will function.
THE MULTIPLE APPLICATION OF PROXIMITY SWITCH
1, test distance
Detects the stop, start, and passing positions of elevators and lifting equipment; detects the position of vehicles to prevent collision detection of two objects; detects the setting position of the working machine, moves the limit position of the machine or component; detects the stopping position of the rotating body, and the valve On or off position; detecting the piston movement position in the cylinder or cylinder.
2, size control
Metal plate punching and cutting size control device; automatic selection and identification of metal length; detection of automatic loading and unloading height; detection of the length, width, height and volume of the article.
3, Check whether the object exists Check if there is a product packing box on the production packaging line; detect whether there are product parts.
4, speed and speed control
Control the speed of the conveyor belt; control the rotational speed of the rotating machine; control the speed and the number of revolutions with various pulse generators.
5, count and control
Detect the number of products flowing on the production line; measure the number of revolutions of a high-speed rotating shaft or disk; count parts.
6, detection abnormal
Check the presence or absence of bottle caps; determine whether the product is qualified or not; detect the lack of metal products in the packaging box; distinguish between metal and non-metal parts; whether the product has tag inspection; the danger zone of the crane alarms; and the escalator starts and stops automatically.
7, metering control
Automatic metering of products or parts; detection of meter or meter pointer range to control number or flow; detection of buoys to control surface height, flow rate; detection of iron buoys in stainless steel barrels; control of upper or lower meter range; flow control, level control.
8, Identification objects
The recognition is based on the code on the carrier.
9, information transmission
ASI (Bus) connects the sensors in various positions on the equipment in the production line (50-100 meters) for data transmission back and forth.
