Frequently Asked Questions about Rotary Encoders

Question number FAQ-0886

What types of output signals does the RP-1700 series have?

The output circuit of the RP-1700 series rotary encoder has a totem pole output as standard.
(Open collector, collector, and line driver outputs are available as options.)

output circuit	Totem pole output	Remarks
totem pole		lo: 20 mA The output resistance Ro is a thermistor with a positive temperature coefficient (PTH). At 25 ℃, the resistance value will be 22 Ω. Load resistance of 470 Ω or more
open collector		DC 40V, below 50 mA
collector		Load resistance, 10 kΩ or more.
line driver		RS422A compatible (equivalent to 26C31)
