AD22 Indicator lamp

Brief description:

AD22-22-25-16 (LED) and AD22-22-25-16-12 (NEON) series of indicator is equally used LED shining chip as light source.

Because of long life, low consumption, small volume and light

weight, it is a product replaced the older generations XD all kinds

of indicator lamp and indicator of neon lamp by new ones.

AD22-25, AD22-22 and AD22-16 indicators produced by our

factory have following character: high brightness,good reliability,

beautiful shape and careful manufacture. Products are well

praised by lots of clients. In order to fit in with quality and demand of user, we develop AD22-22B,C,D,E,G,H,double-color

lamp,position indicator, shining buzzer and mini short indicator

again and use AD22-22G/22GS series button style to design shape,

and it is possible to seal all kinds of international standard symbols

or make to order ones in lampshade. Lampshade is made of

polycarbonate with high intension and has better anti-surge

performance, set up bolt-type connector in it, which will be safer

and more convenient. All improvement will be provided convenience

and perfection for you.

USE:

AD22 series of indicators are used as indicating, foretelling, accident and other signals in the lines of equipment such as electrical power, telecommunication, machine tool, watercraft, textile, printing, mine machinery, etc.

Advantage:

1) Environmental temperature:-25°C~+55°C.

2 )Relative humidity:<98%.
