LED Indicator, G2178B Series

The G2178B series is an assembly using two 2 x 3 mm LEDs in a right-angle mount. Designed to save panel space, the assembly measures just over 4.3 mm(0.170") in width. Long arrays should be located on a pitch of 4.4 mm(0.173") to avoid crowding and tolerance build-up. This series can also be supplied with pinout reversed from that shown by adding "-RL" to the order code of the part number.
Specify part desired as follows:
G2178B/Order Code LED1 + Order Code LED 2
For example: "G2178B/G+Y" designates an assembly with a green LED on top and a yellow LED on the bottom.
"G2178B/(G+Y)-RL" designates the same assembly with leads reversed.
