1). Matters needing attention
    Must choose the power supply voltage: DC5V or DC8-30V
    Must choose leaf spring plate model number if you select hollow shaft encoder
    Please advise the motor speed (RPM) that you actually use
    If you have any other requirements, please provide detail parameters

5). Signal Circuit of encoder
1. The NPN Open Collector -- The NPN Open Collector(NPN) is an interface based on an output circuit with an NPN transistor.
An open collector is the unconnected collector connection of an NPN transistor, whose emitter is connected to earth and whose collector is connected to the output.
2. PNP output
The PNP output is an interface based on an output circuit with a PNP transistor.
3. Push-Pull output(HTL)
High Voltage Transistor Logic functions with a voltage supply in the range 10 and 30 V DC, with 24 V DC being the most usual.
“Low” is defined as an output of between 0 V and 3 V and “high” as between VCC and VCC - 3.5 V.
4. TTL RS-422 output
In a transistor-transistor logic (TTL), both the logical status and the amplification are done by transistors, hence the name.
The TTL output is supplied with either a fixed 5 V voltage or a variable voltage of between 10 and 32 V. For this the low range is defined as the ≤ 0.4 V and the high range as ≥ 2.4 V.
