How to Use splicing connector 2: Examples, Pinouts, and Specs

The Splicing Connector 2 by WAGO is a compact and efficient solution for joining two or more electrical wires or cables. Designed for ease of use, it ensures a secure and reliable connection for signal transmission or power distribution. This component is widely used in electrical installations, control panels, and DIY projects due to its tool-free operation and robust design.

• Electrical wiring in residential, commercial, and industrial installations
• Connecting wires in control panels and distribution boxes
• DIY electronics and prototyping projects
• Signal and power distribution in low-voltage systems

The following table outlines the key technical details of the Splicing Connector 2:

The Splicing Connector 2 does not have traditional pins but features two wire entry points. The table below describes the wire entry points:

1. Prepare the Wires: Strip approximately 10–12 mm of insulation from the ends of the wires you wish to connect.
2. Insert the Wires: Push the stripped end of the first wire into Entry Point 1 and the second wire into Entry Point 2. Ensure the wires are fully inserted and securely held by the spring mechanism.
3. Verify the Connection: Gently tug on the wires to confirm they are firmly secured.
4. Test the Circuit: Power on the circuit and verify the connection is functioning as intended.

• Ensure the wire size is within the specified range (28–12 AWG) for optimal performance.
• Avoid using damaged or corroded wires, as this may compromise the connection.
• Do not exceed the voltage and current ratings of the connector (450 V, 32 A).
• Use the connector in environments within the specified operating temperature range (-40°C to +85°C).
• For added safety, ensure the connector is housed in an enclosure if used in high-voltage or high-current applications.

While the Splicing Connector 2 is not directly programmable, it can be used to connect power or signals to an Arduino UNO. For example, you can use it to connect a 5V power supply to the Arduino's VIN and GND pins.

// Example: Blinking an LED using a power connection via Splicing Connector 2
// Ensure the 5V power supply is securely connected to the Arduino using the connector

int ledPin = 13; // Pin connected to the onboard LED

void setup() {
  pinMode(ledPin, OUTPUT); // Set the LED pin as an output
}

void loop() {
  digitalWrite(ledPin, HIGH); // Turn the LED on
  delay(1000);                // Wait for 1 second
  digitalWrite(ledPin, LOW);  // Turn the LED off
  delay(1000);                // Wait for 1 second
}

1. Loose Connections: If the wires are not securely held, the connection may fail.
   • Solution: Ensure the wires are fully inserted into the connector and the spring mechanism is engaged.
2. Overheating: The connector may overheat if the current exceeds 32 A.
   • Solution: Verify the current rating of your circuit and ensure it does not exceed the connector's specifications.
3. Wire Slippage: Stripped wires may slip out of the connector.
   • Solution: Strip the correct length of insulation (10–12 mm) and ensure the wire is clean and undamaged.

Q1: Can I reuse the Splicing Connector 2?
A1: Yes, the connector is reusable. Simply remove the wires by pulling them out while pressing the release lever (if applicable).

Q2: Is the connector suitable for outdoor use?
A2: The connector is not waterproof. Use it in a weatherproof enclosure if outdoor use is required.

Q3: Can I connect wires of different sizes?
A3: Yes, as long as the wire sizes are within the specified range (28–12 AWG).

Q4: Does the connector require any special tools?
A4: No, the push-in spring technology allows for tool-free operation.
