Through Beam Sensor Function

The et1820 is a family of general purpose through beam sensors in an industrial standard m18 nickel plated brass housing for heavy duty applications.

Through beam sensor function.

The transmitter can be deactivated using a separate test input in order to test the functionality of the through beam sensor. There are three different useful types. Our through beam sensors are reliable in foggy dusty and dirty environments. Current consumption ma 15.

If no object is blocking the light beam to receiver the output is on normally closed. Power on delay time ms 300. Select the sensing width of the sensor to fit the application. They are largely used in industrial manufacturing.

Voltage drop switching output dc v 2 5. Light emitted from the sensor travels through transparent fibers in the cables and emerges at the end of the fiber. Our fiber optic cables are ideal for sensing small objects and are mounted in locations that would be inaccessible to photoelectric sensors. With a through beam sensor a small object can be more easily detected midway between the emitter and the receiver that it can be off.

An area sensor is a through beam sensor which consists of a pair of emitter and receiver with multiple beams. They are useful for simple applications where a basic sensor provide adequate sensing performance. Operating voltage v 10 30 dc. 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.

24 v protection class. Opposed through beam retro reflective and proximity sensing diffused. These sensors are ideal for picking systems for small parts. Culus class 2 source required rated insulation voltage v 32.

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. 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. Area sensors can sense wide areas. The transmitted or reflected beam is carried back to the receiver through different fibers.

Current consumption ma 16. 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.
