Encoder Operation method
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.
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.
Replacement of Older Output Drivers
A logic gate interprets certain input voltages as high (logic 1) or
low (logic 0).
TTL (transistor-transistor-logic): A signal above 2 V is
interpreted as logic 1 and a signal less than 0.8 V is interpreted
as logic 0. The output voltage ranges between 0-5 V.
Package
Each single encoder is packed into a single safe carton with
protecting bubble.
Then all encoders will be put into a bigger carton to prepare
shipment.
Payment terms:
1. T/T, western union, credit card, Paypal, etc
2. 3-5 working days after payment received
3. Encoders will be shipped once ready
