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.

Senyd Pressure Switches

Senyd pressure switches are devices that sense changes in pressure and are used to control the operation of equipment such as pumps, compressors, and motors. They are typically used in applications where it is necessary to monitor and maintain a specific pressure level within a system.

Pressure switches consist of a sensing element that detects changes in pressure, a set point adjustment mechanism to set the desired pressure level, and a switching mechanism that opens or closes an electrical circuit based on the pressure level detected. When the pressure reaches the set point, the pressure switch will actuate and either turn on or off the connected equipment.

There are different types of pressure switches available, including mechanical, electronic, and differential pressure switches, each designed for specific applications and pressure ranges. Pressure switches are commonly used in various industries such as HVAC, automotive, manufacturing, and oil and gas.
