Proximity switches are position switches that can be operated without requiring direct mechanical contact with moving parts. When an object is close to the sensing surface of the switch to the action distance, the switch can be operated without mechanical contact and application of any pressure, thereby driving DC electrical appliances. Or provide control instructions to a computer (plc) device. The proximity switch is a switch-type sensor (ie, non-contact switch). It has the characteristics of a travel switch and a micro switch. It also has sensing performance, reliable operation, stable performance, fast frequency response, long application life, and anti-interference. Strong ability, etc., and has the characteristics of waterproof, shockproof, corrosion resistance. Products are inductive, capacitive, Hall-type, AC and DC.

Proximity switches, also known as non-contact proximity switches, are ideal electronic switch sensors. When the metal detector is close to the sensing area of the switch, the switch can be contactless, no pressure, no spark, and quickly send out electrical instructions, accurately reflecting the position and stroke of the movement mechanism, even for general stroke control, its positioning accuracy, operation Frequency, service life, ease of installation and adjustment, and ability to adapt to harsh environments are incomparable with ordinary mechanical limit switches. It is widely used in machine tool, metallurgy, chemical, light textile and printing industries. In the automatic control system, it can be used as limit, counting, positioning control and automatic protection.

Omron photoelectric switch selection

The Omron photoelectric switch changes the light intensity between the transmitting end and the receiving end into a change of current to reach the intention of exploration. Because the output circuit and the input circuit of the photoelectric switch are electrically isolated from each other, the Omron photoelectric switch Can be used in many places. The new generation of optoelectronic switchgear made with integrated circuit technology and SMT surface equipment technology has intelligent functions such as time delay, widening, external synchronization, anti-interference, high reliability, stability in the operating area, and self-diagnosis. This novel optoelectronic switch is an active optoelectronic exploration system type electronic switch that uses pulse modulation. The cold light sources used are infrared light, red light, green light and blue light, which can be agile and non-touching without damage. Manipulate the status and actions of various solid, liquid, transparent, black, soft, and smoke materials.

Although Omron photoelectric switches have shortcomings such as low response speed, poor accuracy, touch detection that simply damages the object to be detected, and short life, the short interval between the effects of transistors close to the switch cannot directly detect non-metallic materials. However, the new type of Omron photoelectric switch overcomes the above defects, and has the characteristics of small size, multiple functions, long life, high accuracy, fast response speed, long detection interval, and strong resistance to light, electricity, and magnetic disturbance.

At present, this new type of Omron photoelectric switch has been used for level detection, liquid level control, product counting, width discrimination, speed detection, fixed length cutting, hole identification, signal delay, automatic door sensing, color label detection , Punches and shears, and safety protection.

The modulation pulse generated by the vibration circuit of the Omron photoelectric switch passes the reflection circuit, and then the light pulse is radiated by the light-emitting tube GL. When the measured object enters the receiver effect scale, the reflected light pulse enters the phototransistor DU, and the light pulse is demodulated into an electric pulse signal in the receiving circuit, and then amplified by an amplifier and gated and shaped synchronously, and then digitally integrated Or RC integration method eliminates disturbance, and finally triggers the driver to output the photoelectric switch control signal after a delay (or no delay).

Omron photoelectric switches usually have the hysteresis characteristic, so even if the detected object shakes in a small scale, it will not affect the output status of the driver, and then it can be kept in a stable operating area. Together, the self-diagnostic system can also show light receiving conditions and stabilize the work area to monitor the operation of the photoelectric switch at any time.

Omron photoelectric switch is the product of the development of modern microelectronics skills. HGK series infrared photoelectric switch is an upgraded product. Compared with the previous photoelectric switch, it has its own obvious characteristics:

1. It has the function of self-diagnosis and safe operation area instruction, and can tell whether the operation status is reliable in time;

2. Optoelectronic, reflective, and specular optoelectronic devices have the function of avoiding interference with each other, and the equipment is convenient;

3. Set the ES external synchronization (external diagnosis) control end to check whether the photoelectric switch is working normally before running. It can withstand the interruption or detection instructions of the computer or programmable controller at any time. The proper combination of external diagnosis and self-diagnosis can make the photoelectric switch intelligent;

4. The response speed is fast. The response speed of the high-speed photoelectric switch can reach 0.1m. It can perform 300,000 detection operations per minute and can detect small objects moving at high speed.

5.Select application-specific integrated circuit and leading SMT surface equipment technology, which has high reliability;

6. Small size (minimum only 203112mm, light weight, simple equipment debugging, and short circuit protection function.

omron Omron photoelectric switch models include: LX19-001 / 111 in the LX19 series of conventional travel switches, LXK3-20S / T in the LXK3 series, and JLXK1-111 / 411/511 in the JLXK1 series. These products have structures The advantages of simplicity, practicality and low price are favored by users. Imported travel switches: Among the imported travel switches, the WL series, HL series, D4V series, and SZL-WL series are the most representative. Such products have fine workmanship, superior performance, and more outstanding performance in extreme environments, and have won a large number of fans. , But the high price has made many users speechless
