Through Beam Sensor Function

Retro reflective and through beam sensors function as light on operate sensors because under normal operating conditions there is a reflector or a light emitter providing a light beam back to the sensor receiver.

Through beam sensor function.

Light emitted from the sensor travels through transparent fibers in the cables and emerges at the end of the fiber. There are three different useful types. Current consumption ma 15. The transmitter can be deactivated using a separate test input in order to test the functionality of the through beam sensor.

Our through beam sensors are reliable in foggy dusty and dirty environments. The transmitted or reflected beam is carried back to the receiver through different fibers. Wave length nm 633. Our fiber optic cables are ideal for sensing small objects and are mounted in locations that would be inaccessible to photoelectric sensors.

Selecting sensors based on detectable height differences and set distances typical examples with a through beam sensor the lens diameter determines the size of the smallest object that can be detected. Operating voltage v 10 30 dc. Through beam sensors also work reliably in rough environmental conditions such as steam fog or dust thanks to the increased light intensity. Operating voltage v 10 30 dc.

Wave length nm 662. 24 v protection class. Through beam photoelectric sensors from pepperl fuchs offer the most efficient sensing mode which results in the longest sensing ranges highest excess gain. They are useful for simple applications where a basic sensor provide adequate sensing performance.

Power on delay time ms 300. Voltage drop switching output dc v 2 5. If no object is blocking the light beam to receiver the output is on normally closed. Area sensors can sense wide areas.

These sensors are ideal for picking systems for small parts. An area sensor is a through beam sensor which consists of a pair of emitter and receiver with multiple beams. They are largely used in industrial manufacturing. A photoelectric sensor is an equipment used to discover the distance absence or presence of an object by using a light transmitter often infrared and a photoelectric receiver.

Current consumption ma 16. The et1820 is a family of general purpose through beam sensors in an industrial standard m18 nickel plated brass housing for heavy duty applications. Select the sensing width of the sensor to fit the application.
