What the line records
The Omron E3S-AD72 is a PLC accessory in the vertical-orientation form factor, catalogued under PLCs & HMIs, sub-class PLCs (Programmable Logic Controllers), with the order code E3S-AD72 carried verbatim on this line. Listed lifecycle stage is current production, so the part is still an active Omron line item rather than a phase-out or last-time-buy.
Sourcing posture
Panel-side handling note
As a vertical-orientation PLC accessory, the E3S-AD72 is handled as a PLC-side fixture in the panel layout — verify the mounting orientation and any adjacent module keying against the PLC rack before energizing, since the 'vertical orientation' descriptor is the part's defining fit feature.
