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.

Magnetostrictive linear position sensors

Senyd magnetostrictive linear position sensor is a type of sensor used to measure linear position by utilizing the magnetostrictive effect. This sensor consists of a magnetostrictive waveguide, which is a wire or rod made of a magnetostrictive material such as nickel or iron.The sensor works by sending a high-frequency electrical pulse down the magnetostrictive waveguide, which generates a magnetic field. When a movable magnet interacts with this magnetic field, it causes the magnetostrictive material to change its shape slightly, producing a mechanical wave that travels back to the sensor head. By measuring the time it takes for this wave to return to the sensor head, the sensor can accurately determine the position of the magnet along the waveguide.
