Transparent Bottle Detection Sensor, a kind of mirror reflection sensor, is specially engineered for detecting transparent objects. Given that light can pass through transparent objects, regular mirror reflection sensors can't effectively detect them. However, transparent body detection sensors can precisely detect minute changes in light quantity, even at a small differential distance. They achieve this by enhancing the lens optical system and circuit design, ensuring stable and reliable detection. Additionally, their improved design helps minimize the risk of unstable output and malfunctions.
During the detection process, light is reflected twice by the transparent body, which is a characteristic unique to mirror reflection sensors. Compared to through-beam sensors, the attenuation of the received light quantity is more pronounced. Specifically, when light passes through the detection object just once, the attenuation rate of the received light quantity is 3%. In a mirror reflection sensor, this attenuation rate jumps to 6%. Nevertheless, the mirror reflection sensor can still capture subtle light quantity changes through its unique lens optical system and circuit design, thus enabling stable and reliable detection.
When it comes to detecting the presence of a transparent bottle, ordinary photoelectric sensors, proximity switches, and contact sensors have difficulty functioning effectively. In this scenario, mirror reflection sensors demonstrate significant advantages. Their low cost and unique detection method allow them to effectively detect transparent glass and bottles. They can achieve stable and reliable detection even when the transparent body is thin.

Instructions for using transparent bottle detection sensor
Step 1: When the product is powered on, connect the brown wire to the positive pole of DC24V, the blue wire to the negative pole, and the black wire to the output terminal. When the green LED light of the product is stable and on, the subsequent debugging can begin.
Step 2: Fix the product by attaching the sensor to the mounting bracket and ensuring that the sensor's light-receiving surface is not obstructed by the line of sight.
Step 3: Environmental testing (taking a normally open sensor as an example). Use a screwdriver to rotate the potentiometer clockwise and adjust it to the bottom. At this time, the red LED should remain constantly on. Then use a screwdriver to slowly rotate and adjust the potentiometer counterclockwise until the red light stabilizes and goes out. At this point, the sensor can operate at the farthest distance under the current ambient light.
Step 4: Set the working distance of the sensor (taking a normally open sensor as an example). Place the measured object at the desired working distance and perpendicular to the light receiving surface. At this time, the red LED should remain on constantly. (If the red light is not on, adjust the angle between the measured object and the sensor light receiving surface, as well as whether the surface shape of the measured object is appropriate.) Then rotate the potentiometer counterclockwise until the red LED goes out exactly. At this point, slightly adjust the potentiometer clockwise until the red LED is stable and on, and the working distance of the sensor is set.
Note: The reflectivity of the measured object to infrared light, the refraction of infrared light by the surface of the measured object, and environmental light can all affect the normal operation of the sensor. Therefore, changing the working environment requires resetting the sensor.
Q： When the Transparent Bottle Detection Sensor is used, what kind of point needs to be noted?
1. When detecting objects of different materials, the detection distance is different
2. Installation: Due to the size, color, and surface unevenness of the detected object, it will vary. Generally, it should be installed within 90% of the detection distance;
3. The detection surface should be cleaned regularly to avoid affecting product performance.
4. Ambient temperature: -25°C~+65°C; relative humidity: 35~95%HR;
5. Vibration: Durability: 10~55Hz complex amplitude 1.5mm, X, Y, Z directions for 2 hours:
6. Impact: Durability: 500m/s (about 50g), X, Y, Z directions 10 times;
7. When used in a strong magnetic field environment, it is recommended to use shielded wires.
