240V Proximity Switch RXRP-03I-XXF Performance Characteristics Among various types of switches, there is one type that is suitable for approaching objects; Perception; Components of Ability& mdash; Displacement sensor. The use of displacement sensors to control the sensitivity 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 able to; Perception;, The switch will only activate. Usually, this distance is called "&quo;"; Detect distance;. 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 referred to as&quo; Response frequency;. Proximity switch wiring diagram 1) There is a difference between two wire and three wire systems for proximity switches. Three wire proximity switches are further divided into NPN and PNP types, and their wiring is different. 2) The wiring of the two wire proximity switch is relatively simple. The proximity switch is connected in series with the load and then connected to the power supply. 3) Wiring of the three wire proximity switch: connect the red (brown) wire to the positive end of the power supply; Connect the blue wire to the 0V end of the power supply; The yellow (black) line represents the signal and should be connected to the load. The other end of the load is connected as follows: for NPN type proximity switches, they should be connected to the positive end of the power supply; For PNP type proximity switches, they should be connected to the 0V end of the power supply. 4) The load of proximity switches can be signal lights, relay coils, or digital input modules of programmable logic controllers (PLCs). 5) Special attention should be paid to the type selection of the three wire proximity switch connected to the PLC digital input module. PLC digital input modules can generally be divided into two types: one type has a common input terminal that is the negative pole of the power supply, and the current flows out from the input module. In this case, NPN type proximity switches must be selected; Another type of common input terminal is the positive pole of the power supply, and the current flows into the input module. At this time, it is necessary to choose a PNP type proximity switch. Don't make the wrong choice. 6) The two wire proximity switch is limited by working conditions, and when conducting, the switch itself generates a certain voltage drop. When cutting off, there is also a certain amount of residual current flowing through. Therefore, consideration should be given when selecting it. Although the three wire proximity switch has an additional wire, it is not affected by adverse factors such as residual current and works more reliably. 7) Some manufacturers will approach the switch's&quo; Normally open; And&quo; Normally Closed; If the signal is simultaneously led out or other functions are added, please wire according to the product manual. 240V proximity switch RXRP-03I-XXF;  & nbsp;
