VM-480B Induction Clamp

The VM-480B 4”/100mm Induction Clamp provides a precise way to apply a locating signal. It is generally used when it is not possible or convenient to access the conductor to make a direct connection but there is sufficient room to place the clamp around the cable or pipe, or when it is not safe to make a direct connection because the target cable is carrying electricity.

The VM-480B 4”/100mm Induction Clamp is a specialized inductive device, sometimes known as a toroid or coupler. All clamps are optimized to work at specific frequencies. In most cases, clamps are designed to be used at frequencies generally between 8 kHz and 83.1 kHz.
