Photoelectric sensors

Senyd Photoelectric sensors are devices that use light to detect the presence or absence of an object. They work by emitting a light beam (usually infrared, visible, or ultraviolet light) towards the object to be detected. When the object interrupts the light beam, the sensor detects the change in light intensity and triggers a response, such as activating a switch, counting objects, or measuring distance.

There are several types of photoelectric sensors, including through-beam sensors, retro-reflective sensors, and diffuse reflective sensors. Through-beam sensors consist of a separate transmitter and receiver placed opposite each other, with the object passing between them to break the beam. Retro-reflective sensors have a built-in reflector that bounces the light back to the sensor, while diffuse reflective sensors detect the light reflected directly from the object.

Photoelectric sensors are commonly used in industrial automation, packaging, material handling, and robotics applications due to their reliability, versatility, and ability to detect a wide range of objects regardless of color, shape, or material. They are also preferred in applications where contact-based sensors are not suitable due to environmental conditions, such as dust, dirt, or moisture.

Ultrasonic sensors

Senyd ultrasonic sensors are devices that use ultrasonic sound waves to detect the presence of objects, measure the distance to them, or detect their movement. The sensor emits high-frequency sound waves, which then bounce off objects and return to the sensor. By measuring the time it takes for the sound waves to return, the sensor can determine the distance to the object. Ultrasonic sensors are commonly utilized in applications such as parking assistance systems, industrial automation, robotics, and liquid level measurement. They are often used in scenarios where precise distance measurement and object detection are required.

There are many types of Senyd ultrasonic sensors，ultrasonic proximity sensor with switch output,ultrasonic distance sensor with analog and digital output,ultrasonic double-sheet sensor,ultrasonic label sensor,ultrasonic sensor for AGV,etc.
