Linear optocoupler
Pure resistor, non-polarity output
Wide range of analog linear resistance, "on" at the low resistance, "off" at the high resistance
Simple circuit configuration suitable for DC and AC use
Input to output isolation , and low distortion coupling
The LCR‑0203 Series is a linear optocoupler developed by Senba Sensing. The LCR‑0203 Series converts changes in input current into corresponding variations in resistance using an LED paired with a light‑sensitive element. The LCR‑0203 Series operates as a current‑input‑controlled, non‑polarized resistance output device. The LCR‑0203 Series is commonly used in light‑sensitive circuits, analog signal isolation, and applications requiring current‑to‑resistance conversion.
