Description

Analog Linear Optical Coupling is photoelectric component by inputting the different current to control the changes of resistance. It makes use of CdS and LED semi-conductor with rigorous selection, aging and test. The product is widely used by current input control and pure resistance with non-polarity output. Our company own the patent of manufacturing and the patent number is ZL02225334.3.

Characteristics

1. Pure resistor and non-polarity output .
2. Wide range of analog linear resistance, the low “on”resistance, high “off”resistance.
3. Simple circuit configuration suitable for DC and AC use.
4. Input to output isolation, and low distortion coupling.
5. Encapsulation with PPO high-temperature resistant material.

Main characteristic curve

Attention : Soldering pin recommended away from the bottom of optocoupler, soldering time should be as short as possible.

Basic application and testing circuit

Aolittel Technology Co.,Ltd. , specilized in production of various fuse , fuse holder and associated Products with plant area 5,000 m² located in Dongguan city , which is widely known as World's Factory .

Our R&D consist of experienced engineers with rich occupational history from world famous brand .Our production depart always keep at least 200~300 well-trained workers ,as well as some freshman for backup .
