The roller configuration in the area of the Stop Unit is very important to guarantee a continuous flow after releasing the pallet from the Stop Unit. Rollers can be shifted in increments of 68 mm; stub rollers can be used for additional support of the pallet. Sensor holders or RFID tag brackets should be arranged in the roller spacing to avoid stub rollers in these areas. Attention should be taken to have at least three (3) full rollers (not stub rollers!!) in contact with the stopped pallet when the pallet is in its end position of the cushioned Stop Unit. For better performance of the pallet, it is more effective to use additional full rollers to add friction surface than increasing the friction of fewer rollers. 
The following pictures show typical roller configurations in the area of the Stop Unit with the offered roller spacing.
