Product Information

Full details

The WAGO 250-406 is an ideal solution for engineers and hobbyists requiring reliable, compact wire-to-board connectivity in space-constrained electronics projects. Featuring a 6-pole configuration and intuitive push-button mechanism, this terminal block streamlines installation through its push-in CAGE CLAMP S technology, though users should note it is specifically designed for 24-20 AWG wire sizes and requires precise handling for smaller gauge conductors.

FAQs

Can I use this terminal block for high-current applications?

The WAGO 250-406 is rated for currents up to 4A, so it should be used for low-power signal or control applications, not high-current power distribution.

Does it require a special tool for wiring?

No, it features a push-button mechanism, so it is designed to be used without any special screwdrivers or tools.

What is the pin spacing for this unit?

The pin spacing is 2.5mm.

Can I use solid core wire with this terminal?

Yes, solid conductors can be inserted directly using the push-in method without touching the buttons.

What is the operating temperature range?

The device is rated for temperatures between -60°C and 105°C.

Is the unit stackable?

The 250-406 is a 6-pole terminal block; however, terminal strips can be requested with spacers if specific configurations are needed.

Troubleshooting

Wire does not lock into the terminal

Verify the wire gauge is within the 24-20 AWG range and ensure the wire end is stripped to the proper length.

Difficulty inserting fine-stranded wire

Ensure the push-button is fully depressed before inserting the wire to open the clamp mechanism completely.

Test pin does not make contact

Confirm the test pin diameter is exactly 1.3mm and that it is inserted vertically into the designated test port.

Pros and Cons

Pros

  • Tool-free installation for solid wires
  • Space-saving 45-degree angle design
  • High-quality, durable construction
  • Built-in test port for easy troubleshooting

Cons

  • Limited to 24-20 AWG wire gauge
  • Requires manual button press for fine-stranded wires
  • Fixed 6-pole configuration

Setup, Compatibility & Care

To install the 250-406, ensure your PCB layout accommodates the 2.5mm pin spacing. When using solid conductors, simply push the wire directly into the terminal for an automatic connection. For fine-stranded conductors, depress the integrated push-button fully before inserting the wire, then release the button to lock the connection in place.

  • Wire Range: Supports 24 to 20 AWG.
  • Cleaning: Use a dry cloth to remove dust from the terminal housing; avoid chemical solvents that could degrade the plastic housing.
  • Temperature: Ensure the device is mounted away from high-heat components that exceed the 105°C limit.
