Plug-on Footprint
‘Plug-on’ pins are mounted on some Control Panels for connection to commu-
nication devices. The pins are fitted on a plastic spacer, 0.156 inches (3.96mm)
pin centre to centre. There are two rows of 8 pins spaced apart by 4.25 inches
(108mm) pin centre to centre.
The view below is looking at the pins on a Control Panel, onto which the CS2325
Plug-on Adapter plugs. Note that some equipments label the pins 9-16 as ‘1-8’
as well as the pins that are 1 - 8.
