2 x 3 mm, Bi-level PCB Mount
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 mea-
sures 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.
