LLI-2203

LLI-2203 Product Introduction

The LLI‑2203 is a linear optocoupler developed by Senba Sensing. The LLI‑2203 converts changes in input current into corresponding variations in resistance using an LED paired with a light‑sensitive element. The LLI‑2203 operates as a current‑input‑controlled, non‑polarized resistance output device. The LLI‑2203 is commonly used in light‑sensitive circuits, analog signal isolation, and applications requiring current‑to‑resistance conversion.

LLI-2203 Product Features

• Pure resistor and non-polarity output.

• Wide range of analog liner 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.
