Frequently Asked Questions about Roller 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 below 0.5 V. (With a load resistance of 470 Ω or more)

The output circuit of the RP-7400 series (see the figure below) uses a thermistor with a resistance value of 6.8 Ω at 25°C. (I0: 20mA)

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