Feature: 1. The sensor uses the principle of infrared light diffusing to objects: when a person or object enters the sensing area set by the sensor, the sensor outputs the signal; when a person or object leaves the sensing area, the sensor closes the output. 2. Strong anti-interference ability,the working performance is more stable. 3. Smart induction,non-contact switch,more safe and healthy. 4. Small induction angle which is close to straight line. 5. Small size, convenient to install in many places. 6. Applicable to :3C Digital, Medical Electronics, IoT IoT, New Energy, Military/Aerospace, Security Equipment, Household Appliances, Smart Home, Radio and Television Education, Lighting Electronics, Measuring Instruments, Wearables, Automotive Electronics, Network Communications. Specification: Item Type:Infrared Photoelectric Sensor Model:XKC-001A-T-Z12 High And Low Level Signal Output: Positive Output (into the sensing area output high level VCC, leaving the sensor output low level 0V) Voltage:5~12V Distance:10~150cm Package List: 1 x Sensor Note: Induction distance adjustment:1. Place a piece of approximately 80*80cm kraft board at the front of the sensor 70cm (10~150cm according to user requirements).2, turn on the power3. Open the sensor back cover and press the small dot button in the upper right corner.4, about 1~2 seconds, the indicator light is on, release the button, and start to enter the automatic adjustment sensing distance.mode. The sensor and cardboard remain stationary and cannot be blocked by other objects. After waiting for about 10 seconds, the indicator will stop flashing to automatically save the data and automatically return to the normal working mode. Adjust the distance to complete.Precautions for use:1. The infrared receiving device is interfered by strong light (the ordinary indoor light is not affected, the sensitivity is reduced when the light is too strong, and the distance is close). When installing, try to avoid the direct light shining directly onto the probe to make the sensing distance become close to affect the function.2. The infrared sensor is the principle of diffuse reflection of light. It is easily affected by the color of the reflected object (the object being sensed). The white is the farthest, the black is the nearest, and the black and white color sense is quite different. When using it, try not to place a white object in front of the sensor. Avoid malfunctions3. When installing, avoid working in an environment with high dust concentration (because high concentration of dust is equivalent to sensing objects, it will cause the sensor to work incorrectly) to avoid malfunction.The high and low level outputs only provide a high and low level signal, which is suitable for small current control large current, control external current, MCU signal recognition and judgment.
