The photoelectric sensor is a type of sensor that converts the change in light intensity between the transmitting and receiving ends into a change in current for the purpose of detection.

Since the photoelectric switching output circuit and the input circuit are electrically isolated (i.e., electrically insulated), it can be used in many applications. A new generation of optoelectronic switching devices using integrated circuit technology and SMT surface mounting process, with time delay, broadening, external synchronization, anti-interference, high reliability, work area stability, self-diagnosis, and other intelligent functions.

This novel photoelectric sensor is a pulse-modulated active photoelectric detection system type electronic switch, it uses the cold light source has infrared light, red light, green light, and blue light, etc., can be non-contact, non-invasive to quickly and control a variety of solid, liquid, transparent body, black body, soft body, smoke, and other substances state and action. Small size, many functions, long life, high precision, fast response time, long detection distance, strong resistance to light, electricity, and magnetic interference.

     The photoelectric sensor is a device used to detect the distance, absence, or presence of an 
object by using a light transmitter, often infrared, and a photoelectric receiver. They are used 
extensively in machinery, textile, metallurgy, tobacco, railway, war industry and so on. There are 
three different functional types: through-beam (opposed), retroreflective, and diffused type 
( proximity-sensing) .
 
A through-beam (opposed) arrangement consists of a receiver located within the line-of-sight of the transmitter. In this mode, an object is detected when the light beam is blocked from 
getting to the receiver from the transmitter.
 
A retroreflective arrangement places the transmitter and receiver at the same location and uses 
a reflector to bounce the light beam back from the transmitter to the receiver. An object is sensed 
when the beam is interrupted and fails to reach the receiver.
 
A diffused (proximity sensing) arrangement is one in which the transmitted radiation must reflect off 
the object in order to reach the receiver. In this mode, an object is detected when the receiver sees 
the transmitted source rather than when it fails to see it.

     The photoelectric switch (photoelectric sensor) is short for photoelectric proximity switch, which detects the presence or absence of an object by using the blocking bai or reflection of the light beam by the object to be detected, and the circuit is switched on by a synchronous circuit. The object is not limited to metal, and all objects that reflect light can be detected. The photoelectric sensor will be the input current in the emitter converted into a light signal shot, the receiver and then according to the strength of the light received or the presence or absence of the target object detection. Photoelectric sensor smoke alarms are common in security systems and are often used in industry to count the number of movements of a robotic arm.

The diagram as below:

     The Photoelectric sensor have been used for level detection, level control, product counting, width discrimination, speed detection, cut-to-length, hole recognition, signal delay, automatic door sensing, color-coded detection, punching and shearing machines, and security, among many other applications. In addition, the use of infrared concealment, but also in banks, warehouses, stores, offices, and other needs of the occasion as a security guard.
    Commonly used infrared photoelectric switch, is the use of near-infrared light beam reflection principle of the object, by the synchronous circuit induction reflected light intensity and detect the existence of the object or not to achieve the function, photoelectric sensor first issued infrared beam to reach or through the object or mirror on the infrared beam reflection, the photoelectric sensor to receive the reflected beam back, according to the intensity of the beam to judge the existence of the object. There are many types of infrared photoelectric switches, generally speaking, there are mirror-reflective photoelectric switches, diffuse reflective type, slot type, butt type, fiber optic type and other major types.
    The photoelectric sensors are included in the selection of quick and easy automation.
Different photoelectric sensors are used in different situations, for example, fiber optic photoelectric switch is often used in electromagnetic vibration feeder, diffuse reflective photoelectric switch is often used in intermittent packaging machine packaging film feeding, and slot type photoelectric switch is often used in continuous high-speed packaging machine.
