# Connecting Two PNP Proximity Sensors in Series to Control AC Load Hello guys, welcome back to this channel! This video is about how to connect two PNP proximity sensors in series to control an AC load. ## Components Used - **AC Load**: This is the lamp. - **Lamp Holder**: This is where the lamp is connected. - **Magnetic Relay**: Used to operate the load. - **Two PNP Proximity Sensors**: These sensors will help us control the relay. - **SMPS (Switched-Mode Power Supply)**: Converts AC to DC. ## Wiring Diagram Here is the proximity sensor wiring diagram: - **BN (Brown Wire)**: Positive - **BK (Black Wire)**: Output - **BU (Blue Wire)**: Negative The rectangle you see here represents a load or a coil. ### How PNP Proximity Sensors Work A PNP proximity sensor is normally open. When you connect the positive side to the SMPS and the negative side to the SMPS, bringing a metallic object close will close the open contact. This allows current to flow through the black cable. ### Current Flow When the proximity sensor detects the metallic object, the open contact closes, allowing current to flow through the black cable connected to the load or coil. ### Connection Details - The operational voltage for the proximity sensor is from **10 to 30 volts DC**. - The output current is **200 milliamps**. ### SMPS Functionality The SMPS converts AC voltage to DC voltage, which is necessary for the proximity sensors to operate. ### Relay Connection The magnetic relay is a **24V DC relay**. The proximity sensors will control this relay, allowing us to use the normally open and normally closed terminals to operate the AC load. ## Series Connection of Proximity Sensors 1. **Input Connection**: Connect the live and neutral from the circuit breaker to the SMPS (230V AC). 2. **Output Connection**: Connect the brown wire (positive) to the SMPS and the blue wire (negative) to the negative terminal of the SMPS. 3. **Connecting Sensors in Series**: - The output from the first sensor (black wire) connects to the positive of the second sensor (brown wire). - The negative of the second sensor (blue wire) connects to the negative terminal of the SMPS. ### Final Connections - The black cable from the second sensor connects to the relay coil (A2 terminal). - The negative side of the relay connects to the SMPS. ## Testing the Setup After completing the connections, turn on the circuit breaker. The relay should energize when both proximity sensors detect a metallic object simultaneously. ### Important Notes - The sensors must detect the object at the same time for the relay to work. - If one sensor detects the object and the other does not, the relay will not energize. ## Conclusion This is how to connect two PNP proximity sensors in series to control an AC load. If you want to learn more about magnetic relays or SMPS, check the links in the description below. Stay tuned for more videos! # Connecting Two PNP Proximity Sensors in Series to Control AC Load Hello guys! We have number nine on this side, and this is number nine. I'm also going to leave another video in the description about how to connect a proximity sensor to an AC load. This one is in series, but I've made a video about how to connect a PNP proximity sensor to an AC load. If you want to learn more about how to do such a connection, I'm going to leave that video link in the description. ## Video Links - **How to Control AC Load Using a Proximity Sensor**: [Link in Description] - **Video about SMPS**: [Link in Description] - **Video about Magnetic Relay**: [Link in Description] If you want to learn more about this stuff, you can actually go to the description and tap on the link I've pasted there to take you directly to that video. ## Wiring Details This is the live wire. What I'll do is use another cable, and this is going to be the switch wire. I've connected a live from the circuit breaker to number nine, and I'm going to use number five. When the relay energizes, this bar you see here is going to connect from number one and link to number five. ### Relay Functionality When it energizes, it will disconnect this line and connect to number five. The moment it de-energizes, the bar will disconnect number five and link with number one. So, I connect it to normally open. With the normally open, when the two sensors detect the presence of an object, it will work. We have number five at the top here, and the opposite side down here is number one. This cable is what is going to be the switch wire. After this, I'll connect the neutral. ### Neutral Connection This cable is the switch wire that is number five. When the relay energizes, this bar is going to disconnect this line and link to number five. What I'll do is connect the neutral to the lamp holder. This is the neutral. ## Successful Connection So guys, we have successfully connected our two PNP proximity sensors in series to an AC load. This is 230 volts. This is the switch wire, and this is the neutral. I will insert the relay coil, and with the coil, this diagram you see here is the wiring diagram. ### Relay Coil Wiring You have everything down here, and I've actually drawn everything for you to have a clear view. This is a screw lamp, so I'll screw it all the way down. I've turned on the circuit breaker already, and you can see that the bottom has lights out; that is the proximity indicator after I've done the connection in series. ### Sensor Detection These two proximity sensors are supposed to detect the presence of an object at the same time. This is an inductive proximity sensor. I also have a video about how to control AC load using a proximity sensor, where I've explained different types of proximity sensors. ## Types of Proximity Sensors In that video, I explained: - Inductive Proximity Sensor - Capacitive Proximity Sensor - Photoelectric Proximity Sensor - Ultrasonic Proximity Sensor If you want to learn more about proximity sensors, I'm going to leave the link in the description down below. When you go to the description, tap on it, and it will take you to that video for you to watch. ### Everyday Examples The easiest way to see how a proximity sensor works in our everyday life is that they turn off the phone screen when you hold the phone to your ear during a call. That's the help of a proximity sensor installed in the phone. Even when you are listening to audio on WhatsApp, the moment you hold the phone to your ear, you can see that the screen will automatically go off. ## Series Connection The connection is in series; one cannot work without the other. Both sensors must detect the presence of an object at the same time. This is the switch wire I connected to normally open. ### Testing Normally Closed Now, I'm going to connect it to normally closed to see how it works. When I connect it to normally closed (number one), when the relay has not energized, the load is going to automatically work. The moment it detects the presence of an object, then the relay will energize, and the load will go off. ### Relay Operation When it energizes, this close you see here is going to tend to open, and the open is going to tend to close. That's the way the relay works. ## Safety First I'll turn off the circuit breaker and then remove the switch wire from number five to number one as the downside. ### Final Steps Okay guys, we are done with that. I'll turn it on again. Right now, the load is working directly. If you want to learn more, just go to the description down below and click on the relay basics tutorial video. I've explained all the things you need to know to get started with magnetic relays. ## Conclusion If you find this video helpful, consider subscribing to this channel and turning on the notification bell so that anytime I drop a video, YouTube is going to notify you.
