Part Number : LCR0202
Function : Analog Linear Optical Coupling
Package : DIP 4 Pin
Maker : SENTAI ELECTRONIC
Pinouts : 
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.
