Outer diameter 18mm solid shaft 2.5mm miniature rotary encoder ABZ
phase 360 resolution
Matters needing attention
1. Must choose the power supply voltage: DC5V or DC8-30V
2. Must choose leaf spring plate model number if you select hollow
shaft encoder
3. Please advise the motor speed (RPM) that you actually use
4. If you have any other requirements, please provide detail
parameters

Encoder Operation Method
oday most incremental encoders have a Push-Pull (HTL) or RS422
(TTL) output driver, these have replaced most of the older output
circuits like Open Collector NPN, Open Collector PNP, Voltage
Output.
Push-Pull (HTL) circuits, also known as Totem Pole, provide a
signal level which corresponds to the applied supply voltage. The
supply voltage typically ranges from 8 to 30 VDC.
With proper connections you can use the Push Pull interface to
replace true open collector circuits by using an external diode
connected in a way to limit the direction of the current for RS422
(TTL) circuits provide a constant 5 V signal level that is not
dependent on the supply voltage. Two supply voltage ranges can be
selected: From 4.75 to 5.5 VDC (can be used to replace open
collector output drivers) or from 8 to 30 VDC. Using differential
signals the output fully complies to the RS422 standard.
The differential outputs have the highest frequency response
capability and the best noise immunity. To ensure this the receiver
should also be a differential.
