An electrophysiology catheter has a distal electrode section having agenerally-cylindrical,hollow housing body, a lumen and an opening in a sidewall. A flex circuit hasa first portionsupported on the outer surface the housing body, and a second portion thatextends into the lumenvia the opening for connection to cables and/or wires in the lumen. The flexcircuit has a first andsecond magnetic field sensing coil traces generally perpendicular to eachother and a magnetic fieldsensing coil wire generally perpendicular thereto is wound around the housingbody to form anx/y/z position sensor. One or more ring electrodes are carried on the housingbody, separated byring spacers. A force sensor is mounted on a distal end of the housing body,with strain gaugeselectrically connected to the flex circuit. The housing is configured toprovide a distal anchor for apuller tensile.
