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.

inductive and capacitive proximity sensor

Automation without inductive sensors can hardly be imagined. Wear-resistant, reliable non-contact position detection of metallic objects is required wherever automation is used, whether in mechanical engineering, electronics production, automotive, food, or plastics industries.

Senyd offers a wide range of inductive sensors with diverse designs for nearly any application: from standard sensors to sensors with increased switching distance, hygienic sensors, high-pressure sensors, ex-zone sensors for hazardous areas, and factor 1 sensors. Some sensors have an additional ceramic or PTFE coating so that weld spatter, for example, cannot adhere to them. Sensors that are both factor 1 and all-metal are also available. 

Aided by inductive sensors from Senyd, you can automate, monitor, and control processes and conditions at the highest quality, even in extreme environments.

Capacitive sensors detect objects and the fill level of all non-conducting materials, liquids, pellets, and powders directly or through a container wall.

The Smart Level technology of the sensors compensates for moisture, foam and adhesion of all sorts – even through glass and plastic walls up to 10 mm thick. This makes the sensors ideal as fill level sensors for conductive media. And guarantee you high application security.

Our sensors are available in diverse designs, even especially small ones. As adhesive sensors, they fit flexibly to the housing shape and are easily removable.
