MOC-7811 Slotted Opto Isolator Module (Encoder Sensor) - MOC7811

MOC-7811 Slotted Opto Isolator Module - Precision Encoder Sensor

The MOC-7811 is a compact slotted opto isolator module. It's designed for reliable non-contact object detection. This module features an infrared LED and a photodiode in a U-shaped casing. It acts as a precise optical switch, ideal for accurate positional sensing. When an object blocks the IR light, the photodiode's logic level changes. This signal is easily processed by microcontrollers. Widely used in robotics and automation systems, it provides essential feedback. Its durable design suits various embedded and industrial applications.
