SMA Connector Kit

• It has been well established that 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 1N.m is generally being specified by connector manufacturers for the tightening
  of precision connectors and around 0.5 N.m for brass bodied connectors.
• Based on the tried and tested TBN 2 Torque Breaking Handle and Minor Slipping Torque Screwdriver, tools are available to accurately tighten SMA connectors and to ensure that over tightening cannot occur. The TBN 2 is used with an open ended spanner (usually 8mm), while the pre-set Minor Screwdriver with special end fitting 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.

IFR (Impact Free Resetting) Cams

• The patented design of Torqueleader Torque Limiting Screwdrivers enables pre-set torque values to be applied in both left-hand and right-hand directions. The screwdrivers are thus described as “bi-directional”.
  
• The design action of these normal cammed screwdrivers is such that when the tool reaches its pre-set torque value the mechanism disengages from the drive thus limiting the torque applied. Further rotation of the screwdriver handle resets the mechanism ready for the next torqueing operation. During resetting a small reaction may be felt by the Operator which, in certain applications in the Electronics Industry could be undesirable.
  
• The introduction of torque screwdrivers fitted with IFR Cams eliminates this small reaction rendering the resetting of the mechanism impact free - hence IFR - Impact Free Resetting” When required, IFR Cams replace the cams normally fitted to Minor, Standard and TLS 1360 screwdrivers.Tools fitted with the IFR ams are identified by a small groove around the outside diameter of the cam section of Minor handle and a small slot on the front face of Standard and TLS 1360 Cams.
