Frequently Asked Questions about Rotary Encoders

The totem pole output is an output circuit that combines two transistors. Since the High or Low level is determined, there is no state of uncertainty in the signal level. The output level in the High state is above 10 V, and the output level in the Low state is a signal below 0.5 V.

The output resistance R ₀ of the RP-1700 series output circuit (see figure below) uses a thermistor with a resistance value of 22 Ω at 25°C.

A thermistor is a type of resistor that changes its electrical resistance in response to temperature changes.
