Shaanxi Inductive Proximity Switch HQ80-996SZ-C has good performance and switching frequency. Inductive proximity switch 1. Principle: An oscillator is composed of an inductor coil, capacitor, and transistor, which generates an alternating magnetic field. When a metal object approaches this magnetic field, eddy currents will be generated inside the metal object, causing the oscillation to stop. This change is amplified by the back pole and converted into a transistor switch signal output. 2. Features: A. Good performance, switching frequency, greater than 200Hz B、 Can only sense metals. It is applied to various mechanical equipment for position detection, counting signal pickup, etc. Wiring instructions: 1. The three wires of the DC three wire proximity switch are: brown wire - positive blue wire of the power supply - negative black wire of the power supply - output signal. 2. AC two wire switch: connect the load and proximity switch in series and connect them to the AC power supply end. Wiring form 1) There is a difference between two wire and three wire 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 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 subject to working conditions. When conducting, the switch itself generates a certain voltage drop, and when cutting off, there is also a certain 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 may simultaneously introduce the "normally open" and "normally closed" signals of proximity switches, or add functions. In this case, please wire according to the product manual. Shaanxi Inductive Proximity Switch HQ80-996SZ-C has good performance and switching frequency.
