OE-39C SERIES

Concentric Shaft Encoder Two Channels With Standard Quadrature 2-Bit Code

 

The Series OE-39 rotary encoder switches use quadrature output (2-bit repeating gray code).

In a quadrature rotary optical encoder two detectors are used to provide output “A” and “B”. The code rotor either blocks the infrared light or allows it to pass to the detectors. As the shaft turns the rotor, the output changes state to indicate position. The resulting output is two square waves that are 90° out of phase.

External pull-up resistors from each output to the power source are needed when interfacing with an open collector output to provide the output with the high state voltage when the photo transistor is “off”. Base current is supplied in a photo transistor when light strikes the detector effectively grounding the output.

This “on” or “off” digital arrangement allows the open collector to interface with commonly used integrated circuit technologies such as TTL, TTL LS, CMOS and HCMOS.
