Description
The G78B is one of the most popular indicators in LAN hubs and network controllers. 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. For long arrays, also investigate our G784B series which is designed to replace 4 assemblies and is matched to the G78B in height, depth and lamp location.
