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.

Liquid Level switch

This level switch is also called Float sensor, liquid level sensor, reed switch etc.

They are used wherever it is necessary to control and regulate the level of liquids (e.g. water, oil, etc.). The sensor has a float equipped with a magnet, which moves vertically along the guide tube under the influence of the buoyancy force of the liquid, causing the reed switch located in the tube to short circuit or open. They are usually mounted in the bottom or lid of the tank, so they can be used to control the lower or upper level of the liquid. They are made of stainless steel and can be used in a wide range of temperatures.
