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.
