Encoder Technical Theory
An incremental rotary encoder outputs a certain amount of Pulses per Revolution. The higher this PPR number, the smaller the angle between each pulse. This PPR number is fixed for ordinary incremental encoders. Programmable incremental encoders can adjust this value to a desired number by a software change.
Output drivers:
Today 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.
Shipment
1. Goods can shipped via TNT, FedEx, UPS, DHL, EMS, etc.
2. You could select the express according to your requirements if freight collector
3. If you do not have any courier account, we will check and find a cheapest and safety express for you.
