Fuji APX510-24G Green LED Lamp – 24V AC/DC Replacement
Essential Panel Indicator for AR22/AR30 Pushbuttons & Pilot Lights
When pilot lights fail in control panels, operators lose critical visual feedback. The Fuji Electric APX510-24G provides the exact green LED replacement for illuminated pushbuttons and pilot lights across Fuji's AR22, DR22, AR30, and DR30 series, operating on 24V AC or DC without modification.
Upgrading from incandescent to LED delivers immediate benefits: extended service life, reduced heat output, lower current draw, and elimination of predictable bulb replacement schedules. This lamp's dual AC/DC compatibility simplifies inventory and prevents installation errors during critical maintenance.
Sold as a pack of 2, providing both an immediate replacement unit and a spare for maintenance teams.

LED Advantages Over Incandescent in Control Panels
Original incandescent lamps in AR-series pushbuttons had limited lifespans, especially in high-temperature panel environments. The APX510-24G transforms this scenario with 0.8W consumption versus higher-wattage incandescent equivalents, generating less heat per lamp position.
The LED element contains no fragile filament vulnerable to vibration failure—a critical advantage in machine tool panels, packaging machinery, and applications with routine vibration exposure.
The BA9S/13 bayonet base provides direct mechanical compatibility with existing lamp holders in compatible Fuji pushbuttons and pilot lights. Installation requires seconds—simply twist out the old lamp and twist in the new one.
Compatible Fuji Series
- AR22 / DR22 – 22mm illuminated pushbutton series
- AR30 / DR30 – 30mm illuminated pushbutton and selector switch series
- AH16 series – compact finger-sized pushbuttons
- φ25 illumination switch series
- Compatible pilot light indicator units with same voltage and base format
For compatibility verification, check for a BA9S bayonet socket with 24V supply voltage in your specific pushbutton model.
AC/DC Compatibility Benefits
Fuji's APX510 series LED lamps handle both AC and DC current waveforms through integrated rectification, eliminating the need to verify panel circuit type before installation.
At 12 mA on AC and 11 mA on DC, current draw is sufficiently similar that brightness variation between supply types is negligible. This feature simplifies inventory management for facilities operating mixed AC and DC control circuits across different machine generations.
APX510 Color Range Options
The APX510-24 series covers standard panel indicator colors. All variants share identical BA9S/13 base and 24V AC/DC specifications—only the LED color differs:
- APX510-24R – Red
- APX510-24Y – Yellow
- APX510-24A – Amber
- APX510-24W – White
Frequently Asked Questions
Is the APX510-24G compatible with both AC and DC control circuits?
Yes. It is rated for 24V AC and 24V DC and handles both without modification. Current draw is 12mA on AC and 11mA on DC—functionally identical for panel indicator applications.
How many lamps come in one pack?
The APX510-24G is sold as a pack of 2. Most users deploy one as an immediate replacement and maintain the other as a panel-side spare for regularly serviced machinery.
Will this lamp fit my AR22 pushbutton directly, or does it need an adapter?
No adapter required. The BA9S/13 bayonet base provides direct physical replacement for original Fuji lamp holders in AR22, DR22, AR30, and DR30 pushbuttons. Simply twist out the old lamp and twist in the new one to lock.
How does the LED version compare to the original incandescent in terms of brightness?
LED lamps generally provide comparable brightness to incandescent versions under normal panel lighting conditions. The significant practical advantages include extended service life, reduced heat output, and lower current consumption—without noticeable visual difference to operators.
Are other colors available in the same specification?
Yes. The APX510-24 series includes red (24R), yellow (24Y), amber (24A), and white (24W) in addition to green (24G). All share identical BA9S/13 base and 24V AC/DC ratings, making them mechanically interchangeable with only color variation.
