The reflective photoelectric switch is a light sensing device that emits and receives the body. The diode emits 940nm itself and receives near-infrared light as the light source. The external object of the transistor converts the reflective light chip detection into an electrical signal to transmit information.
The light-collecting chip is a phototransistor. When used, the light source reflected by the reflector must make the light-collecting chip work in the signal area and occupied area respectively to ensure that the signal is connected
The photoelectric switch must maintain timing with the object being detected to ensure signal transmission timing.
The photoelectric switch must maintain stable contact with the object being detected to ensure stable signal transmission.
Photoelectric switches must avoid misjudgments caused by strong light interference.

1.How does a photo interrupter work?
The sensor emits infrared light from the LED emitter to the receiver. When an object blocks the light between these components, the sensor records the change, providing a way to detect motion, calculate rotational speed, or implement object detection.
2. How to use photointerrupter correctly?
Since the output circuit and input circuit of the photoelectric switch are electrically isolated (that is, electrically insulated), it has small size, multiple functions, long life, high precision, fast response speed, long detection distance, and strong resistance to light, electricity, and magnetic interference. Advantages, so it can be applied in many situations. The following is the correct use of photoelectric switches:
(1) When using the EL8307 photoelectric switch to avoid obstructions, for some goods such as colored goods, weakly reflective goods, goods with large gaps between small pieces, transparent goods or under sunlight or halogen light, the photoelectric switch will The switch will not work because the light is blocked.
(2). Self-regulation. Before using the winding machine photoelectric switch, please check whether the switch itself is intact and whether the appearance is intact, etc.
(3). Direction adjustment. When the photoelectric switch senses goods or something other than the motor turntable, you can adjust the sensitivity knob counterclockwise and rotate it counterclockwise until no foreign objects are sensed. After that, it is worth noting that live operation is strictly prohibited and please pay attention to safety.
3. What are the different types of photo interrupters?
The two basic types of photointerrupters are the transmissive type (gap type) and the reflective type.
