Miniature LED indicator lamp

The SIEMENS 52AEB2 is a T3-1/4 miniature LED bulb designed for low-voltage indicator applications. It fits panels or devices that require a BA9s bayonet base and a red status light. The unit is supplied new and ready for direct replacement in compatible equipment.

Low heat and minimal power draw

Operating at 6 volts and drawing only 15 mA, the bulb generates very little heat during normal use. Silent solid-state operation adds no audible noise to the host device. An average rated life of 25 000 hours reduces the frequency of maintenance cycles.

Simple drop-in for BA9s sockets

The miniature bayonet base allows tool-free installation in existing BA9s holders without wiring changes. Its compact T3-1/4 envelope fits tight indicator housings where larger lamps cannot be accommodated. The red emission suits status, fault or power-on indication needs.

Questions about this item

How do I install the 52AEB2 T3-1/4 bulb and what is the common mistake?

Align the BA9s bayonet pins with the socket slots, push in and twist until it locks; the common mistake is forcing it straight in without twisting, which bends the pins.

What maintenance or replacement will the 52AEB2 bulb need later?

The LED is rated for 25,000 hours of average life; after that the red light output will dim and the whole miniature bulb must be replaced.

What limit appears first when the 52AEB2 runs continuously?

At 15 mA and 6 V the forward voltage and junction temperature reach their design ceiling, so thermal derating of the red LED is the first sustained-use limit.
