Photoelectric switch (photoelectric sensor) is the abbreviation of photoelectric proximity switch, which uses the detected object to block or reflect the beam, and the synchronous loop gating circuit, so as to detect the presence or absence of the object. Objects are not limited to metal, all objects that reflect light can be detected. The photoelectric switch converts the input current into an optical signal on the transmitter, and the receiver then detects the target object according to the intensity or presence of the received light. Common photoelectric switch smoke alarms in security systems, often used in industry to count the number of movements of robotic arms.

Main types of photoelectric switches:

 

Thru-beam photoelectric switch

 

It consists of a transmitter and a receiver, which are structurally separated from each other, creating a switch in the event that the beam is interruptedSignalVariation.

 

Features: Distinguish opaque reflective objects; The effective distance is large, because the time for the beam to cross the sensing distance is only once; It is not susceptible to interference and can be used reliably and appropriately in the field or theredustenvironment; The consumption of the installation is high, both units must be laidcable。

 

Diffuse mode photoelectric switch

When the switch emits a beam, the target produces diffuse reflection, and the transmitter and receiver form a single standard part whenElectric switchWhen enough combined light returns to the receiver, the switching state changes. Characteristics: The effective action distance is determined by the reflection ability of the target, and is determined by the surface properties and color of the target; Small assembly overhead, when the switch consists of a single component, usually can achieve coarse positioning; Adjusted with background suppressionmeasurementDistance; Sensitive to dust on the target and sensitive to the changed reflective performance of the target.

Specular reflective photoelectric switch

The case consisting of a transmitter and receiver is a standard configuration with the beam emitted from the transmitter on the opposite sidereflectorbyreflection, i.e. back to the receiver, a change in the switching signal is generated when the beam is interrupted. The passage time of light is twice the duration of the signal. Features: Identification of opaque objects; With the help of the mirror component, a high effective distance is createdrange； It is not easily disturbed and can be used reliably and appropriately in the field or dusty environment.
