The AMP 173280-3 connectors mate to AMP 173279-3 connectors (or similar)
on the IP modules. This provides excellent connection integrity and utilizes
gold plating in the mating area. Threaded metric M2 screws and spacers
(supplied with Acromag IP modules) provide additional stability for harsh
environments (see Drawing 4502-148 for assembly details).
Pin assignments for these connectors are defined by the IP module
specification and are shown in Table 2-1.

edge connector. Connector pins are designated by a letter and a number.
The letter indicates which side of a particular connector the pin contact is on.
