IR Photoelectric Encoder حساس 4Pin

IR Photoelectric Encoder

The IR Photoelectric Encoder Sensor 4Pin is a versatile and compact sensor module designed to detect objects or measure rotational speed using infrared technology.

It employs a groove IR opto-coupler to sense interruptions between an infrared emitter and receiver, enabling it to count obstructions over time.

This functionality makes it ideal for applications such as speed measurement, object counting, and position sensing. With its low power consumption, adjustable sensitivity, and compatibility with ZKEEP0Z–ZKEEP1Z systems, this sensor is a reliable choice for hobbyists, robotics enthusiasts, and industrial applications.

Features :

• Digital Output: Delivers a clean TTL digital signal (0 and 1).
• LOW state when the sensor is not obstructed (LED indicator lights up).
• HIGH state when the sensor is obstructed (LED indicator turns off).
• Adjustable Sensitivity: Includes an on-board potentiometer for fine-tuning sensitivity to meet specific application requirements.
• Low Power Consumption: Operates with a current consumption of only ZKEEP2Z, ideal for energy-efficient projects.
• Wide Voltage Range: Compatible with power supplies from ZKEEP3Z to ZKEEP4Z, ensuring flexibility in various circuits.
• Compact Design: Measures 32 x 14 x ZKEEP5Z, facilitating easy integration into space-constrained projects.
• Mounting Friendly: Equipped with ZKEEP6Z diameter mounting holes for straightforward installation.
• Analog Output: Provides an analog output (AO) alongside digital output for more precise measurements.
• Strong Driving Ability: The digital output can drive more than ZKEEP7Z, enabling reliable interfacing with microcontrollers and other devices.

Applications :

• Motor Speed Detection: Measures the rotational speed of motors or wheels by counting interruptions from a slotted disk, ideal for robotics and automation projects.
• Object Counting: Counts items passing through the sensor’s ZKEEP17Z groove, such as pellets in a chute or products on a conveyor belt.
• Position Limit Detection: Detects when an object reaches a specific position, useful in mechanical systems or automated setups.
• Alarm Systems: Can be interfaced with relays, limit switches, or active buzzers to trigger alarms when an obstruction is detected.
• Robotics: Supports position encoding and, with adaptations, line-following applications in hobby robotics projects.
