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

The Splicing Connector 2 by WAGO is a compact and reliable electrical connector designed to join two or more electrical wires or cables. It ensures a secure and durable connection, making it ideal for both low-voltage and high-voltage applications. This connector is widely used in electrical installations, industrial automation, and DIY projects due to its ease of use and robust design.

• Electrical wiring in residential, commercial, and industrial environments
• Connecting wires in control panels and distribution boxes
• DIY electronics and prototyping projects
• Signal transmission in low-voltage circuits
• Temporary or permanent wire splicing in automotive and machinery repairs

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

The Splicing Connector 2 does not have traditional pins but instead 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 want to connect.
2. Open the Connector: If the connector has a lever, lift it to open the wire entry points.
3. Insert the Wires: Push the stripped ends of the wires into the respective entry points until they are fully seated.
4. Secure the Connection: Close the lever (if applicable) to lock the wires in place. For push-in connectors, ensure the wires are firmly inserted.
5. Verify the Connection: Gently tug on the wires to confirm they are securely held in place.

• Ensure the wire size is within the specified range (28–12 AWG) for optimal performance.
• Avoid over-stripping the wires, as this may expose excess conductor and increase the risk of short circuits.
• Use the connector only within its rated voltage (450 V AC) and current (32 A) limits.
• For high-vibration environments, double-check the wire connections to prevent accidental disconnection.
• Store the connectors in a dry, dust-free environment to maintain their integrity.

While the Splicing Connector 2 is not directly programmable, it can be used to connect wires from sensors or actuators to an Arduino UNO. Below is an example of wiring a temperature sensor to an Arduino using the splicing connector:

// Example: Reading temperature data from a sensor connected via Splicing Connector 2
// Ensure proper wire connections using the splicing connector for secure signal transmission.

const int sensorPin = A0; // Analog pin connected to the temperature sensor
int sensorValue = 0;      // Variable to store the sensor reading

void setup() {
  Serial.begin(9600); // Initialize serial communication at 9600 baud
}

void loop() {
  sensorValue = analogRead(sensorPin); // Read the sensor value
  float voltage = sensorValue * (5.0 / 1023.0); // Convert to voltage
  Serial.print("Sensor Voltage: ");
  Serial.println(voltage); // Print the voltage to the Serial Monitor
  delay(1000); // Wait for 1 second before the next reading
}

1. Loose Connections:

   • Cause: Wires not fully inserted or improperly stripped.
   • Solution: Ensure wires are stripped to the correct length (10–12 mm) and fully seated in the connector.

2. Overheating:

   • Cause: Exceeding the current or voltage rating of the connector.
   • Solution: Verify that the connected circuit does not exceed 32 A or 450 V AC.

3. Wire Slippage:

   • Cause: Using wires outside the specified size range (28–12 AWG).
   • Solution: Use only compatible wire sizes and check the connection after insertion.

4. Connector Damage:

   • Cause: Excessive force during wire insertion or removal.
   • Solution: Handle the connector gently and avoid using tools that may damage the housing.

Q1: Can the Splicing Connector 2 be reused?
A1: Yes, the connector can be reused. Simply remove the wires by pulling them out gently while lifting the lever (if applicable).

Q2: Is the connector suitable for outdoor use?
A2: The connector is not waterproof. For outdoor applications, use a weatherproof enclosure to protect it from moisture and dust.

Q3: Can stranded and solid wires be mixed in the same connector?
A3: Yes, the connector supports both stranded and solid wires, even in the same connection.

Q4: How many wires can be connected using the Splicing Connector 2?
A4: This specific model supports two wires. For more connections, consider using a larger splicing connector model.
