Conveyor switch

Introduction to SM-3025C Disk shaped Plastic Proximity Switch: Proximity switch is a type of switch type sensor (i.e. contactless switch), which has the characteristics of travel switch and micro switch, as well as sensing performance. It is reliable in action, stable in performance, fast in frequency response, long in service life, strong in power, and has characteristics such as waterproof, shockproof, and corrosion-resistant. The products include inductive, capacitive, Hall, AC, and DC types. According to its external shape, it can be divided into cylindrical, square, groove, perforated (through) and separated types. The cylindrical type is more convenient to install, but its detection characteristics are the same. The detection position of the groove type is on the inner side of the groove, used to detect objects passing through the groove. The through type is rare in China, while it is more commonly used in Japan. It can be used to assemble small parts such as small screws or balls and buoys into water level detection devices. Performance characteristics: Among various types of switches, there is one type that has the ability to handle objects close to it; 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;. Disk shaped plastic proximity switch SM-3025C wiring: 1. Two wire system Two wire system wiring is particularly simple. Connect the proximity switch and load in series, then connect the power supply, and use the matching detection object material to approach the proximity switch, and the proximity switch will act. 2. The three wire lead has color markings for proximity switches. The three wire lead has color markings, including the color of the positive wire of the power supply (red or brown), the color of the 0V wire of the power supply (blue), and the color of the signal wire (yellow or black). The three-wire wiring of proximity switches is different because there are two types of three-wire wiring: PNP and NPN. If it is an NPN type proximity switch wiring, locate the proximity switch signal wire, connect the load, and then connect the load to the positive pole wire of the proximity switch power supply. If it is a PNP type proximity switch, also find the signal line of the proximity switch, connect the load, and then connect the load to the 0V line of the proximity switch power supply. How to determine whether a proximity switch is NPN type or PNP type depends on the characteristics of the diode, where P represents the anode (+) and N represents the cathode (-). Also, because the diode cuts off the forward conductor in the opposite direction. A transistor can be seen as composed of two diodes. And it is known that approaching the positive pole of a switching power supply is equivalent to the base of a transistor, so the starting point is the positive pole of the power supply. Using the resistance range of a multimeter, connect the red probe to the positive side of the power supply and the black probe to the 0V power line and signal line respectively. If the resistance is small when measured separately, exchange the probes for measurement. If the resistance is large when measured separately, then the proximity switch can be an NPN type, and vice versa, it can be a PNP type proximity switch.
