WARNING

 

 

Due to the decentral controller the operator of the rotary gripper 
needs not to be near the product so that third persons might be 
endangered by the rotary/gripper operation. 
Always  switch  off  the  controller  and  disconnect  the  module 
from  the  compressed  air  supply  and  secure  against  being 
switched on again unintentionally when you work on the DG 20 
rotary gripper. The signals of the control system may cause un-
intentional  movements  of  the  module  which  may  lead  to  per-
sonal injuries.

 

 

2.1.4 Installation and fastening possibilities

 

The DG 20 rotary grippers can be installed in a vertical and horizontal position. 

The  Afag  module  components  are  provided  with  a  precise  module  centring  which 
guarantees a high and repetitive accuracy of fit during installation, operation and ex-
change of a module. 

There are 2 centering sleeves with a diameter of 7 x 3 mm each at the short end and 
on the rear of the module. 
There are 4 centering sleeves with a diameter of 5 x 2.5 mm each on both sides of 
the gripper drive. 
 
Please see the dimension drawing for the dimensions of the mounting holes and the 
distance between the holes (page 18).
