Wamco KW-105AL Alphanumeric Minitron Display  
Written by AnubisTTP on 2009-02-27  


Wamco made minitron-type displays in a wide variety of styles. These tiny KW-105AL filament displays are 16 segment devices, and can display a full alphanumeric character set. Though they are wider than the KW-105S pictured above, digit height is the same at only 8mm. The KW-105AL has a very unusual base, which consists of 17 tiny tubular sockets arranged in a "C" shape. The special socket designed to work with this display has pins which mate with the tubular sockets on the base of the display.
