12V 2W Solenoid Valve Documentation

Component Name

12V 2W Solenoid Valve

Overview

The 12V 2W Solenoid Valve is an electro-mechanically operated valve designed to control the flow of fluids, gases, or air in various industrial, commercial, and residential applications. This solenoid valve operates on a 12V DC power supply and consumes 2W of power, making it a compact and energy-efficient solution for automation and control systems.

Functionality

The primary function of the 12V 2W Solenoid Valve is to regulate the flow of fluids or gases by opening or closing a valve in response to an electrical signal. When the valve is energized (i.e., 12V DC power is applied), the solenoid coil generates a magnetic field, which causes the valve to open, allowing fluid or gas to flow through the valve. Conversely, when the power is turned off, the valve returns to its default closed position, preventing fluid or gas flow.

Pin Configuration

12V 2W Solenoid Valve Pinout and Connection Guide
The 12V 2W Solenoid Valve is a widely used IoT component in various applications, including automation, robotics, and industrial control systems. It has a total of 3 pins, which are explained below:
Pinout:
1. Positive Power Supply (VCC) Pin
Function: Provides 12V power supply to the solenoid valve
Polarity: Positive (+)
Connection: Connect to a 12V power source (e.g., battery, power adapter, or voltage regulator)
2. Negative Power Supply (GND) Pin
Function: Provides a ground connection for the solenoid valve
Polarity: Negative (-)
Connection: Connect to a ground point (e.g., GND pin on a microcontroller or a grounding point on a PCB)
3. Signal (SIG) Pin
Function: Receives a digital signal from a microcontroller or other control device to operate the solenoid valve
Polarity: Active High ( logic HIGH to activate the valve, logic LOW to deactivate)
Connection: Connect to a digital output pin on a microcontroller, PLC, or other control device
Connection Structure:
To connect the 12V 2W Solenoid Valve, follow these steps:
Step 1: Power Supply Connection
Connect the VCC pin to a 12V power source (e.g., battery, power adapter, or voltage regulator)
Connect the GND pin to a ground point (e.g., GND pin on a microcontroller or a grounding point on a PCB)
Step 2: Signal Connection
Connect the SIG pin to a digital output pin on a microcontroller, PLC, or other control device
Ensure the signal pin is configured as an output and is capable of providing a logic HIGH signal (typically 5V or 3.3V)

Important Notes:
Ensure the power supply voltage is within the specified range (12V) to avoid damaging the solenoid valve.
Use a suitable current rating for the power supply, as the solenoid valve requires 2W of power.
When connecting the signal pin, ensure the microcontroller or control device is configured to provide a logic HIGH signal to activate the solenoid valve.
Consult the solenoid valve datasheet for specific operating conditions, such as temperature, pressure, and flow rates.
