What are Torque Wrenches?
A Torque wrench is a tool or connector accessory that is used to tighten/open a coaxial connection. Each coaxial connector requires a certain amount of torque to be applied to it to ensure a proper connection. Exceeding this connector torque value can result in damaging the connector or connection interface and not applying enough torque can result in a loose connection. The way most torque wrenches are built is that once they are tightened to their torque limit, the wrench sort of breaks to avoid excessive tightening the connector which can damage the system. This type if called Break Over. Other types make a clicking sound once the torque limit is reached.
Torque wrenches for different types of coaxial connectors are different, for example, SMA, N-Type etc. The torque is the measure of how much force needs to be applied to rotate an object about its own axis. The unit of torque is N m (Newton meter) or lb·in (pound inch) or lb·ft (pound-foot). The expression of the torque is torque = force(N) x length(m).
When selecting a torque wrench the following factors should be considered:
Connector Type: This represents the type and size of connectors that can be handled by the torque wrench. Connector types include TNC, N-type, SMA, MPC3, 7/16 DIN etc. The size and the shape of the torque wrench will depend on the type of connector used. Each torque wrench is designed for a specific type of coaxial connector.
Coupling torque: It represents the preset torque limit of the torque wrench and is represented in N-m or N-cm or in-lbs.
Torque accuracy: Represents the closeness of torque provided by the instrument to the preset torque value. It is represented in ± X %.
