The 68 series provides screw connections at an 11mm pitch, with one row of 2–16 poles. Choose a C, S or R configuration and either A mounting ends or a compact B housing. R models have visibly bent terminals. Clear covers are shown on all six configurations. Select by the complete model code because screw size, tightening torque and impulse rating differ.
