Исследовательские заметки

1. What this is

A3PJ-90A11-24EG is an Omron A3 illuminated pushbutton.

2. Part-number decode

  • Series: Omron A3
  • Type: illuminated pushbutton
  • Illuminated: yes

3. Compatibility & ordering

Omron makes industrial command switches (A22 22mm, A16 16mm — unitized, contact in the model code), illuminated pushbuttons/pilot lights (A3, M2), and a widely-used B3 PCB tactile-switch family. Match by size, function (pushbutton/selector/indicator/E-stop), colour, illumination, and contact arrangement, then use the Omron datasheet to confirm the exact colour and voltage encoded in the part number.

4. Data-quality note

The Omron product line/type is identified; the detailed configuration (colour, contact, voltage) is left to the datasheet rather than guessed. Flagged decoded-partial.

Краткое руководство по монтажу

Panel cutout: 22mm. Insert from the front of the panel, secure with mounting nut from behind (tighten to 2-3 Nm).

Contact block: Snap or screw the contact block onto the rear of the button body. Ensure the contact block orientation matches the wiring diagram — NO terminals are usually marked.

Wiring: Use 0.5-2.5mm² stranded wire with ferrules. Tighten screw terminals to 0.8 Nm. Test the button function before energizing the circuit.

Устранение неисправностей

Button doesn't respond when pressed

Check the contact block first — it's the most common failure point. Test continuity across the NO or NC terminals with a multimeter. If no click is felt, the return spring in the head may be broken.

Works intermittently

Contact block contacts are pitted or burned. Replace the contact block — don't try to file the contacts. Check if the rated cycle count has been exceeded.

Button feels mushy or doesn't click

The spring return mechanism in the button head is worn. Replace the head. The contact block can usually be reused if it tests OK.
