Product Information

Full details

This guide is for electronics engineers, developers, and hobbyists needing a compact and efficient way to connect solid and stranded conductors on a PCB. The WAGO 2-pole pushbutton terminal block offers quick, tool-free termination for solid wires and easy conductor insertion/removal for stranded wires via its integrated pushbuttons, significantly speeding up assembly. A minor consideration is the fixed 45° entry angle, which might influence layout in extremely space-constrained designs.

FAQs

What types of conductors can be used with this terminal block?

This terminal block is designed for solid conductors (via push-in) and fine-stranded conductors (via pushbutton). Both types should be within the 0.5mm² to 2.5mm² range.

Do I need special tools to wire this terminal block?

No, for solid conductors, no tools are required for termination. For fine-stranded conductors, the integrated pushbuttons allow for tool-free insertion and removal.

What is the maximum current and voltage rating?

The terminal block has a maximum current rating of 17.5A. The maximum voltage rating should be confirmed with WAGO's official documentation for specific application standards.

What does the 45° conductor entry angle mean for my design?

The 45° angle directs wires away from the PCB surface, which can save vertical space and make routing of wires more organized, especially in compact enclosures.

How do I remove a wire once it's connected?

For fine-stranded conductors connected via the pushbutton, simply press the button again to release the clamp and pull the wire out. For solid conductors connected via push-in, a small flathead screwdriver or a specific tool may be required to release the clamp (consult WAGO's guidelines for the exact method).

What is the pitch of this terminal block?

The pitch is 5mm, which refers to the distance between the centers of adjacent terminals.

Is this terminal block suitable for high-vibration environments?

Yes, the CAGE CLAMP® connection technology used by WAGO is known for its vibration resistance and secure contact retention.

Troubleshooting

Conductor not held securely

Ensure the conductor is stripped to the correct length and inserted fully. For stranded conductors, ensure the pushbutton is fully released after insertion. Verify the conductor size is within the specified range (0.5mm² to 2.5mm²).

Difficulty inserting conductor

For solid conductors, ensure the entry is clear and the conductor is straight. For stranded conductors, make sure the pushbutton is fully depressed before attempting insertion.

Poor electrical connection / intermittent signal

Check that the conductor is properly seated. Ensure the wire is not damaged and the stripping is clean. Verify the CAGE CLAMP® connection is functioning correctly by gently testing conductor retention. Ensure the PCB solder joints are sound.

Terminal block not seating correctly on PCB

Check PCB hole dimensions and alignment. Ensure no debris is obstructing the terminal block pins or PCB holes.

Pros and Cons

Pros

  • Tool-free connection for solid conductors speeds up assembly.
  • Pushbutton access simplifies connecting and disconnecting stranded wires.
  • Compact design with 5mm pitch is suitable for dense PCBs.
  • Reliable CAGE CLAMP® connection ensures secure electrical contact.
  • 45° conductor entry angle improves accessibility and saves space.

Cons

  • Fixed 45° conductor entry angle may not suit all layout requirements.
  • Primarily designed for fine-stranded conductors via pushbutton; solid conductors use push-in.
  • Specific current rating (17.5A) and voltage limitations must be observed.
  • Grey color may not match all aesthetic design choices.

Setup, Compatibility & Care

Setup:

  1. Ensure the PCB has appropriately sized solder pads and through-holes compatible with a 5mm pitch terminal block.
  2. Insert the terminal block directly onto the PCB, aligning the pins with the designated holes.
  3. Solder the pins to the PCB following standard soldering procedures.
  4. For connecting solid conductors, strip the insulation and push the conductor directly into the appropriate terminal entry point until it is securely held.
  5. For connecting fine-stranded conductors, push the integrated pushbutton to open the clamp, insert the stripped conductor, and release the button to secure the connection.

Compatibility:

  • Designed for solid conductors from 0.5mm² to 2.5mm² (AWG 20 to 14).
  • Designed for fine-stranded conductors from 0.5mm² to 2.5mm² (AWG 20 to 14).
  • Maximum current rating: 17.5A.
  • Maximum voltage rating: Check WAGO specifications for precise voltage limits based on application standards.

Care:

  • Avoid exposing the terminal block to excessive moisture, dust, or corrosive environments.
  • Regularly inspect connections for signs of damage or corrosion, especially in harsh environments.
  • Cleaning should be done with a dry or slightly damp cloth. Avoid abrasive cleaners or solvents that could damage the plastic housing or contacts.
