OMRON Sensor Models

OMRON Sensing Components detect, measure, analyze, and process various changes that occur on productions sites, such as changes in position, length, height, displacement, and appearance. They also contribute to predicting and preventing future events.

The OMRON sensor is a sensor with photoelectric devices as conversion elements. It can be used to detect non-electricity that directly causes changes in light quantity, such as light intensity, illuminance, radiation temperature measurement, gas composition analysis, etc .; it can also be used to detect other non-electricity that can be converted into light quantity changes, such as part diameter, surface roughness, strain , Displacement, vibration, speed, acceleration, as well as the identification of the shape and working state of objects.
The photoelectric sensor has the characteristics of non-contact, fast response and reliable performance, so it is widely used in industrial automation devices and robots. In recent years, new optoelectronic devices have emerged, especially the birth of CCD image sensors, which has opened a new page for the further application of OMRON sensors.

 1. Eddy current proximity switch
Such switches are sometimes called inductive proximity switches. It uses a conductive object to generate an eddy current inside the object when it approaches this proximity switch that can generate an electromagnetic field. This eddy current reacts to the proximity switch, causing the internal circuit parameters of the switch to change, thereby recognizing whether or not a conductive object is approaching, thereby controlling the switch on or off. The object that this proximity switch can detect must be a conductor.
 2. Capacitive proximity switch
The measurement of such a switch is usually one plate constituting the capacitor, and the other plate is the outer shell of the switch. This enclosure is usually grounded or connected to the equipment enclosure during the measurement process. When an object moves to the proximity switch, whether it is a conductor or not, due to its proximity, the dielectric constant of the capacitor must be changed, so that the capacitance changes, so that the state of the circuit connected to the measuring head also occurs Changes, which can control the switch on or off. The objects detected by this proximity switch are not limited to conductors, but can be insulated liquids or powders. 3. Hall proximity switch Hall element is a magnetic sensitive element. A switch made of Hall elements is called a Hall switch. When the magnetic object moves closer to the Hall switch, the Hall element on the switch detection surface changes the internal circuit state of the switch due to the Hall effect, thereby identifying the presence of a magnetic object nearby, and then controlling the switch on or off. The detection object of this proximity switch must be a magnetic object.
 Omron sensor --- Omron series
The photoelectric switch can be used in various applications. In addition, when using the photoelectric switch, attention should also be paid to the environmental conditions, so that the photoelectric switch can work normally and reliably.

OMRON Sensor Models
(1) Matters needing attention:
1) Avoid strong light sources
Photoelectric switches generally work stably when the ambient illumination is high. However, it should be avoided that the optical axis of the sensor is directly facing the strong light sources such as sunlight and incandescent lamps. When the angle between the optical axis of the sensor (receiver) and the strong light source cannot be changed, a shading plate or a long shading tube can be installed around the sensor.
  2) Prevent mutual interference
An effective way to prevent mutual interference is to set the emitter and receiver crosswise, and to increase the group distance when more than 2 groups. Of course, using different frequency models is also a good way.
  3) Influence of mirror angle
When the measured object is shiny or encounters a smooth metal surface, the reflectivity is generally very high, which has a mirror effect. At this time, the projector and the detection object should be installed at an angle of 10-20 ° to make its optical axis Not perpendicular to the detected object, thereby preventing misoperation.

Working principle:
Omron sensors use photoelectric devices as conversion elements. It can be used to detect non-electricity that directly causes changes in light quantity, such as light intensity, illuminance, radiation temperature measurement, gas composition analysis, etc .; it can also be used to detect other non-electricity that can be converted into light quantity changes, such as part diameter, surface roughness, strain , Displacement, vibration, speed, acceleration, as well as the identification of the shape and working state of objects.

The OMRON position sensor is a sensor that uses a photoelectric element as a detection element. It first converts the measured changes into changes in optical signals, and then further converts the optical signals into electrical signals with the help of photoelectric elements. The photoelectric sensor is generally composed of three parts: light source, optical path and photoelectric element. The optical measurement and control system made by the different operating principles of luminous flux on the photoelectric element is diverse, according to the output properties of the photoelectric element (optical measurement and control system) can be divided into two categories, namely analog photoelectric sensor and pulse (switch) type photoelectric sensor. The analog photoelectric sensor converts the measured into a continuously changing photocurrent, which has a single-valued relationship with the measured. Analog photoelectric sensors can be divided into three categories: transmission (absorption), diffuse reflection, and shading (beam blocking) according to the method of measurement (detection of target objects). The so-called transmission type refers to the object being placed in the light path, the light energy emitted by the constant light source passes through the object to be measured, and part of it is absorbed, the transmitted light is projected onto the photoelectric element; the so-called diffuse reflection type refers to the light emitted by the constant light source Projected onto the object under test, then reflected from the surface of the object under test and projected onto the photoelectric element; the so-called light-shielding type refers to when the luminous flux emitted by the light source is partially blocked by the object under test, so that the luminous flux on the projected photoelectric element Change, the degree of change is related to the position of the measured object on the optical path.

Photodiode is the most common light sensor. The appearance of the photodiode is the same as that of a general diode, except that its casing has a window embedded with glass to facilitate the incidence of light. In order to increase the light receiving area, the area of the PN junction is made larger. In the biased working state, it is connected in series with the load resistance. When there is no light, it is the same as the ordinary diode. The reverse current is very small, called the dark current of the photodiode. , Generate electron-hole, called photoelectric sensor carrier. Under the action of an external electric field, photoelectric carriers participate in conduction, forming a reverse current much larger than the dark current. This reverse current is called photocurrent. The magnitude of the photocurrent is proportional to the light intensity, so the electrical signal that changes with the light intensity can be obtained on the load resistance. In addition to the function of the photodiode to convert the optical signal into an electrical signal, the phototransistor also has the function of amplifying the electrical signal.

OMRON Sensor Models

The appearance of the photosensitive triode is not much different from that of the general triode. Generally, the photosensitive triode only leads out two poles-the emitter and the collector, and the base is not led out. The shell also opens a window for light to enter. In order to increase the illumination, the base area is very large, the emission area is small, and the incident light is mainly absorbed by the base area. The collector junction is reverse biased during operation, and the transmitter junction is biased forward. The current flowing through the tube when there is no light is the dark current Iceo = (1 + β) Icbo (very small), which is smaller than the penetration current of the general triode; when there is light, a large number of electron-hole pairs are excited, making The current Ib generated by the base electrode increases. The current flowing through the tube at this moment is called the photocurrent. The collector current Ic = (1 + β) Ib. It can be seen that the phototransistor has higher sensitivity than the photodiode.
