The correct tightening of SMA Connectors used in RF cabling applications is essential to ensure optimum performance. This is particularly important in high frequency applications using stainless steel or beryllium - copper bodies.
A torque value of around 1 N.m is generally being specified by connector manufacturers for the tightening of precision connectors
and around 0.5 N.m for brass bodied connectors.
A MTBN 2 Break-Over wrench & Minor Torque Screwdriver are tools available to accurately tighten SMA connectors and to ensure that over tightening cannot occur. The MTBN 2 is commonly used with an open ended spanner (usually 8mm), while the pre-set Minor Screwdriver with a Crowsfoot Spanner Head enables vertical access in places where conventional torque tools cannot be used. Spanners are available to suit the A/F sizes of all the
major connector manufacturers.
The tools and a range of end fittings can be purchased individually or in boxed kits. They can also be supplied to suit individual users needs for pre-set torque value, end fittings and access restrictions.
