Allen-Bradley 800MR-PA16BA 22mm Blue Lighted Button 120V

The Allen-Bradley 800MR-PA16BA is a transformer-type illuminated push button from the Bulletin 800MR 22.5 mm range, with a blue lens. Radwell specifies the closely related 800MR-PA16AAS as a push button unit, momentary contact, illuminated, transformer flush head, standard illumination transformer 120V AC 50/60 Hz, amber, 1 N.O. 1 N.C., small screw - the same PA16 configuration with a different colour and termination suffix.

Transformer illumination is the reason these devices outlast full-voltage ones. A small transformer at the device steps the panel's 120V AC control voltage down for the lamp, so the filament runs well within its rating and lamp replacement intervals stretch from months to years on a continuously lit indicator.

Bulletin 800MR is Rockwell Automation's 22.5 mm push button range. The Rockwell 800MR selection guide documents the illumination coding used across the family - full voltage 24V AC/DC incandescent models as 800MR-QA24RA / GA / AA, and transformer 120V AC incandescent models as 800MR-PA16RA / GA / AA, with the trailing letters denoting red, green and amber. The guide also notes that operators come standard with stab terminations, and that a letter K is added to the end of the catalog number for large screw contact terminations (S for small screw).

Note: The transformer 120V AC and flush-head readings are from the Radwell specification for 800MR-PA16AAS. The Rockwell 800MR selection guide documents the colour codes RA (red), GA (green) and AA (amber) but does not list BA - the blue reading is an inference from that pattern and is unverified, as is the contact configuration.
