FMA Torque Verification Wrench

RoHS Tightening torque data management Preset Interchangeable Head Judgement Wireless


Confirm the completion of your tightening processes by counting the number times the torque wrench "clicks" indicating that it achieved the set torque. With the FMA system, a wireless module sends a signal to a receiver box. The receiver box can be connected directly to a PLC or to Tohnichi CNA-4mk3 Count Checker, which counts the clicks and gives alerts to the worker. FMA features 900 MHz for those facilities who have restrictions on using the standard 2.4Ghz version FH256MC
