DIGITAL CONTACTING
The Digital Contacting Encoder is commonly referred to by such
names as Digital Panel Control, Bit Switch, Gray Switch and Digital
Switch. All such names are synonymous with a device whose output
is a digital gray code signal, rather than a conventional potentiometric
voltage ratio output.
The advantage of the Digital Contacting Encoder is that it permits the
direct entry of digitized analog data into a digital circuit without A/D

conversion. The two (2) channel gray coded signal of this incremental
encoder allows the user’s decoder circuit to sense analog direction of
rotation, as well as up-down counter capabilities . . . all without the
time and cost required for A/D conversion. This approach can reduce
memory overhead, wiring and wiring interconnects, and can provide
greater MPU program speed.
