T-1-3/4 Double Height, Right-Angle LED Assembly G74B Series The G74B is a double height indicator assembly made up of two T-1-3/4 LEDs. It is available with a wide choice of colors, brightnesses, operating voltages and even in bi-color. It allows the designer to place two indicators one on top of the other and is the vertical implementation of the G642B which is horizontal. For multiple pair applications, the G75B interlocking version is recommended for ease of holding the lamps in good alignment. This series is also available with polarity of each LED reversed. Specify that by adding “-RL” after the order code. 4.8±.5 6.2 7.6 Hole pattern: 0.9 (.035") dia. on 2.54 (0.1") centers 12.4 4.8 2.54 2.54 2.5 3.5 min 2.54 5±1 11±.3 0.5 + - + - TopLED BottomLED Grn + Red or Yel + Grn + Red or Yel + Single Color Bi-color Specify part desired as follows: G74B/Order Code + Order Code For example: “G74B/I+G” designates an assembly with a red LED on top and a green LED on the bottom. “G74B/(I+G)-RL” designates the same assembly with reversed polarity.
