G24 Infrared sensor Photoelectric sensor switch

The mechanical quantity to be measured, such as displacement, pressure change into an electrical capacitance sensor. Therefore, capacitive sensors can be divided into pole pitch change type, area change type, change the media type categories. Pole pitch change type is generally used to measure the tiny lines or due to force displacement, pressure, vibration caused by the pole pitch changes (see capacitive pressure sensor). Area change type is generally used to measure the angular displacement or larger linear displacement. Change media type commonly used in level measurement and a variety of medium temperature, density determination and humidity.

Principle

The working principle of the photoelectric switch is that when the beam emitted by the emitter is blocked or partly reflected by the object, the beam receiver whereby makes a judgment and reacts.

Throuht-beam type

Through-beam bype photoelectric switch is designed that via the light beam between opposite-mounted transmitter and receiver, the object passing through these two devices will interrupt the light beam and start the receiver.

 

Diffuse type
Diffuse reflection type photoelectric switch integrates the transmitter and the reciver. Light reflected by the photoelectric switch is reflected back to the receiver by the detected object.

 

Retroreflective type
Retroreflective type photoelectric switch also integrates the transmitter and the receiver, Its difference from other models is that reflecotr is used to relfect light to the photoelectric switch. Though the object between the photoelectric switch and reflector can reflect the light, it is much less efficient than the reflector so as to cut down reflected light.

 

Convergence reflection type (condensation type)
The working principle of convergence reflection type photoswitch is similar to that of direct reflection type one, while its projector and light receiver focus on boject distance, only when the object presents to the focus can the photoswitch actuate.
