Hunan Yongzhou LJ12A3-4-Z/EX-T proximity switch threaded cylindrical proximity switch proximity switch, as the name suggests, is a switch that sends a control signal when the switch approaches an object. A proximity switch is a position switch that can be operated by mechanical direct contact with moving parts. When an object approaches the sensing surface of the switch to the operating distance, it does not require mechanical contact or any pressure to activate the switch, thereby driving DC electrical appliances or providing control commands to computer (PLC) devices. Proximity switch is a type of switch type sensor (i.e. contactless switch) that combines the characteristics of travel switch and micro switch, as well as sensing performance. It has reliable operation, stable performance, frequency response, long application life, strong capability, and features such as waterproofing, shock resistance, and corrosion resistance. The products include inductive, capacitive, Hall, AC, and DC types. Proximity switch, also known as contactless proximity switch, is an electronic switch quantity sensor. Performance characteristics: Among various switches, there is one type that has an impact on objects that are close to it; lquo; Perception; rquo; Components of Ability; mash;&mash; Displacement sensor. The use of displacement sensors to control the characteristics of approaching objects to achieve the purpose of switching on or off is called proximity switches. When an object moves towards the proximity switch and approaches a certain distance, the displacement sensor will only be activated; lquo; Perception; rquo;， The switch will only activate. Usually, this distance is called& lquo; Detection distance; rquo;。 But different proximity switches also have different detection distances. Sometimes the object being tested is moved towards the proximity switch one by one at a certain time interval, and then left one by one, repeating this process continuously. Different proximity switches have different response capabilities to the detected object. This response characteristic is called& lquo; Response frequency; rquo;。 Technical parameters and characteristics: 1. Detection distance: 1-15mm. 2. Working environment: Temperature; Nash: 20 ℃~+50 ℃& nbsp; ：IP66。3、 Working power supply: C12V; mash;30V。4、 Current during conduction: 20mA (when the load resistance is less than 670Ω). Load short circuit protection. 5. Leakage current when disconnected: less than 0.6 mA. 6. Indicator light: When conducting, the indicator light; lquo; Always on& rquo;； When disconnected, indicator light& Flash every 3 seconds; rquo;。7、 Unsaturated voltage drop during conduction: 10.5V (when the load resistance is greater than 670Ω). Proximity switches are widely used in aviation, aerospace technology, and industry. In daily life, such as hotels, restaurants, automatic doors, and automatic hot air fans, there are applications. In terms of anti-theft, important places such as data archives, accounting, finance, museums, and vaults are usually equipped with anti-theft devices composed of various proximity switches. In measurement techniques, such as length and position measurement; In control technology, such as displacement, velocity, and acceleration measurement and control, a large number of proximity switches are also used.
