#4. Our History
In 1988-1998, The elder generation produced optical products in a
small workshop in Dongtou District, Wenzhou, laying a solid
foundation for the subsequent development of encoders and infrared
optics.
In 1999, The founder was employed by Shanghai No.1 Optical Factory
as a senior engineer, engaged in optical research and development,
and made many scientific breakthroughs.
In 2000, The founder took the opportunity of privatization of
state-owned enterprises and planned to establish a company.
In 2001, Shanghai Hengxiang Optical Electronics Co., Ltd. was
formally established, and the first S38 series products are
independently developed in the same year.
In 2008-2019, Formally joined Alibaba's to expand overseas markets,
and obtained ISO Quality Management System Certification.
In 2010- 2014, Three invention patents ,five new utility patents
and a CE-ATC certificate was obtained.
Awarded the Honor of Shanghai High-tech Enterprise and Alibaba
Integrity Pioneer Enterprise.
In 2015-2020, Moved factory to Songjiang Chuangyi International
Industrial Park ,Obtained QA international certification and QMS
quality management system certification.
In 2021, Obtained 14 new utility patents.
#5. Encoder technology 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.
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.
