What are the range and impact of light touch switches? As a light touch switch manufacturer, Dongguan Dongkun Electronic Technology Co., Ltd. will give you a detailed introduction on this issue below, please know more about these four points.
1. Touch switch can be used in various applications to prevent strong light source. Touch switch can generally work stably in high ambient illumination. However, it should be avoided to direct the optical axis of the sensor to the strong light sources such as sunlight and incandescent lamp. When the angle between the optical axis of the sensor (receiver) and the strong light source can not be changed, a light shielding plate or a light shielding cylinder can be installed around the sensor.
2. To prevent mutual interference, MGK series of new touch switches usually have the function of automatically preventing mutual interference, so there is no need to worry about mutual interference. However, when the HGK series counter-fire infrared light touch switches are installed side by side, the adjacent groups and mutual interference should be prevented. The most effective way to prevent this kind of interference is to set the projector and receiver crosswise, and to open the group spacing when exceeding the two groups. Of course, using different frequencies of the machine is also a good way. The effective way to prevent mutual interference of HGK series reflective light touch switch is to open the interval. Moreover, the farther the detection distance is, the greater the interval should be. The specific interval should be determined according to the debugging situation. Of course, different types of machines with different working frequencies can also be used.
3. The influence of mirror angle: When the measured object is glossy or meets a smooth metal surface, its reflectivity is generally very high, and it has the function of approximating mirror. At this time, the projector and the detected object should be installed at an angle of 10-20 degrees, so that their optical axis is not perpendicular to the detected object, so as to prevent misoperation.
4. Exclude the influence of background: When using reflective diffuse projector and receiver, sometimes the light switch can not be detected steadily because the detected object is close to the background, touch the switch lightly or the background is smooth and other objects with high reflectivity. Therefore, distance-limited projectors and receivers can be used instead, or methods such as removing background objects, removing background objects, painting background objects into matte black, or trying to make background objects rough and dark can be used to eliminate them.
5. Use of self-diagnostic function: When the device is in use, it may sometimes cause slight offset of optical axis, lens contamination, dust deposit, external noise, environmental temperature exceeding the range due to the influence of desktop or background and vibration. These problems may cause the light touch switch to deviate from the stable working area. At this time, the self-diagnosis function of the light touch switch can be used to send out notifications through the STA BLITY green stability indicator to remind users to adjust it in time.
I hope you can understand these four points in the process of using them, so that the use of light switch can be more integrated into our life.
