LCR 0202 Analog Optotransistor for Sound Control

 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.

Characteristics

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