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 designed for reliable non-contact object detection. It features an infrared LED and a photodiode housed in a U-shaped plastic casing, acting as a precise optical switch. This module is ideal for applications requiring accurate positional sensing without physical wear. When an object or encoder disc slot blocks the IR light, the photodiode's logic level changes. This signal can be easily processed by a microcontroller or discrete hardware. Widely used in robotics, automation systems, and rotary encoders, the MOC-7811 provides essential feedback for movement and position changes. Its durable design makes it suitable for various embedded systems and industrial applications.
