8Pcs Slot Type Speed Sensor Module, IR Optocoupler Comparator for Motor Speed Detection Pulse Counting

8Pcs Slot Type Speed Sensor Module, IR Optocoupler Comparator for Motor Speed Detection Pulse Counting Description

Slot-Type Photoelectric Detection: This sensor module uses a slot-type photoelectric optocoupler to detect object interruption within the slot , making it ideal for object counting, position sensing, and motion detection applications.
Direct Digital Signal Output: The integrated comparator circuit converts the optical signal into a stable digital output, allowing direct connection to microcontroller GPIO pins without the need for additional signal conditioning components.
Wide Operating Range: Supports a operating voltage range from 3.3V to 5V, making it easy to use with , and other common development boards and embedded control platforms.
Speed Measurement and Counting: Designed for use with encoder disks, slotted wheels, and moving objects, this module is well suited for rotational speed measurement, pulse counting, position feedback, and automation sensing tasks.
Compact and Non-Contact Design: The non-contact optical sensing method helps reduce mechanical wear, while the compact PCB layout with clearly labeled power and signal pins makes wiring, installation, and prototype integration simple and convenient.
