Variocrimp 4 crimping tool; for insulated and uninsulated ferrules; from 0.25 mm² to 4 mm²



Application notes:

  • With Variocrimp 4, the built-in crimping pressure control automatically adjusts force to the conductor cross-section used.
  • Only one crimping station is needed to handle the specified conductor size range.
  • Uniform, compact crimping on all four sides for high conductor retention.
  • No need to center the conductor into the ferrule.
  • Conductor and ferrule insertion possible from both sides (for left- and right-handers).
  • Built-in ratchet mechanism ensures gas-tight crimp connection.
  • Crimping tools open automatically after crimping operation is complete.
  • Ergonomical handles.

What is a “gas-tight” connection?

In a gas-tight connection, the conductor and the ferrule are compressed, eliminating all spaces. Under normal atmospheric conditions, neither a liquid nor gaseous medium can penetrate the crimped connection.

Oxidation between crimped single conductors is prevented, virtually eliminating the possibility of any increase in the crimped connection’s resistance. In some exceptional cases, minute, isolated spaces may be present. However, these instances can be considered as closed off due to the twisted conductor.

Inadequate crimping can allow the conductor to be pulled out of the connection. Hollow spaces also remain, permitting oxidation formation

and leading to an increase in contact resistance.

Elevated resistance is detrimental for signal transmission, as the signal flow is damped (weakened), and for power transmission, as power loss and, hence a temperature increase due to contact (risk of fire) can result.

Crimping tools with built-in ratchets are recommended, such as the WAGO crimping tools. These tools only open after the crimping process has been fully completed. Space-saving crimping from all four sides is ideal for spring clamp termination.

Cross section data for ferruled conductors indicated for WAGO products is based on this crimping method.
