Guide for the use of proximity switches
guide for the use of proximity switches 2 ------ series and parallel connection of NPN and PnP (taking the htl-q series proximity switches of hwl as an example)
the series and parallel connection of proximity switches are often encountered on the installation site. Many engineers have questions about the series and parallel connection of proximity switches, how many circuits can be connected in series and parallel, First, the series parallel circuit of proximity switch is summarized as follows with htl-q05 series proximity switch listed in German capital market as an example
htl-q series proximity switches and HRP series photoelectric switches are economic sensors launched in Asia. They are known as "ace" switches in the industry because of their high quality, reliability, good quality and low price. They are widely used in automatic assembly line manufacturing, injection molding machines, printing and packaging machinery, die casting machines, textile machinery, conveyor belts, elevators, cranes, lifting machinery, metal processing equipment In the field of industrial control and automation such as construction machinery and equipment, delivery vehicles, etc., htl-q05n1e is commonly represented by NPN, with power supply VDC, 5mm approach distance, NPN output mode, response frequency 800Hz, resolution 1 minute, Brown is the positive VCC of the power supply, blue is the negative 0V of the power supply, black is the NPN output out, after power supply, when there is no object approaching, the output out is high level, and when there is an object approaching, the output out is low level
htl-q05p1e is represented by the commonly used PNP. The power supply is VDC, and the proximity distance is 5mm. The PNP output mode Jinan experimental machine is now very high-end. The response frequency is 800Hz. Brown is the positive VCC of the power supply, blue is the negative 0V of the power supply, and black is the PNP output out. After power supply, when there is no object approaching, the output out is low level, and when there is an object approaching, the output out is high level. (end)
