Rockwell Automation 440F Safedge Pressure Sensitive Safety Edge System - Manual (Page 11)

3.2.9 To ensure complete seal apply more
adhesive on the Safedge Profile around
grommet/cable exit and sealing lip of the
closing cap.
3.2.10 Axial profile connector 440F-A0061S is used
for extensions and repairs (see steps 1, 2, 3,
6 and 7) for the 440F-E0110 series of profiles
only. For other types, use straight pin connectors.
