Media transfer unit 

NSE-A3 138-V4-P's have two media transfer interfaces for 

pneumatics, hydraulics or vacuum. 
The pressure-sealed coupling mechanisms do not open until 

coupling elements are connected. The coupling process can be 

connected when depressurized. Pressure may only be transmitted 

to the clamping device when the clamping pallet is fully locked on 

the clamping modules. The NW3 coupling nipples to be used  

(I.D. no. 1374387) for the side of the clamping pallet as well as the 

relevant installation drawing can be requested from SCHUNK. 
NSE-A3 138-V4-P1 has four open media transfer unit interfaces. 

The coupling side is to be made with a Ø5 mm bore hole with 90° 

counterbore Ø9 mm. While coupling, always make sure that the 

media transfer unit interfaces are positioned so they are aligned 

with each other.
