Multi-Couplings
Nitto Kohki
Nitto Kohki Multi Cupla connect several media lines in a single stroke. Through a common plate, 2 to 24 circuits - air, hydraulic oil, water and electrics combined - are coupled simultaneously and with positional accuracy. This significantly reduces set-up and tool-change times in automation and eliminates mix-ups of individual lines.
The series range from the manual MAM plate through lockable MAM-B versions to the lever-operated MALC and the large MALS/MALT plates for many circuits. Spring centring and floating mounting compensate for positional tolerances; non-spill Cupla elements prevent media loss on disconnection.
