Analog Linear Optical Coupling LCR0202
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.
