HC-89 Interrupt Sensor
The HC-89 Interrupt Sensor is a compact, slotted optical switch module designed for precise object detection, position sensing, and counting applications. Featuring an infrared LED and phototransistor pair housed in a U-shaped gap, this sensor reliably detects when an object passes through or interrupts the optical beam - making it essential for encoder wheels, motor speed measurement, end-stop detection, and automated counting systems. Available now at The Engineer Store, Bengaluru with fast shipping and full technical support.

Key Features
- Slotted Optical Design: U-shaped gap with aligned IR emitter and detector provides clean, reliable beam-break detection without physical contact
- Onboard LM393 Comparator: Converts analog phototransistor output into a clean digital HIGH/LOW signal, eliminating noisy or ambiguous readings
- Adjustable Sensitivity: Built-in potentiometer lets you fine-tune the detection threshold to accommodate different object sizes and ambient conditions
- Visual Status LED: Onboard indicator LED lights up when the beam is interrupted, enabling quick testing and debugging without a microcontroller
- Wide Voltage Compatibility: Operates reliably at both 3.3V and 5V logic levels, ensuring seamless integration with Arduino, ESP32, Raspberry Pi, and more
- Microsecond Response: Extremely fast switching time makes it ideal for high-speed counting, RPM measurement, and real-time position feedback
- Simple 3-Pin Interface: Just VCC, GND, and Digital Output - connect directly to any microcontroller GPIO pin with no additional components required
- Non-Contact Detection: Optical sensing means zero mechanical wear, ensuring long operational life even in continuous-use applications
- Compact & Mountable: Small form factor with mounting holes allows easy integration into enclosures, robotic arms, conveyor frames, and 3D printer assemblies
Why Choose the HC-89 Interrupt Sensor?
- 100% Authentic: Sourced directly from trusted, authorized suppliers - guaranteed genuine components and reliable performance
- Plug-and-Play Simplicity: No complex wiring or external pull-up resistors needed; the onboard comparator circuit handles signal conditioning for you
- Versatile Application Range: From simple object counting to precision motor encoders, this single module serves dozens of use cases across hobby and industrial projects
- The Engineer Store & Repeatable: Optical beam-break detection delivers consistent results unaffected by object color, surface texture, or material (as long as the object is opaque)
- Excellent for Learning: Clear operating principle (light interruption) makes it an ideal teaching tool for understanding digital inputs, interrupts, and sensor interfacing
- 1-5 days shipping: Dispatched from our Bengaluru warehouse with same-day delivery available within Bengaluru city
- Full Technical Support: Expert guidance via email and WhatsApp to help you with wiring, code, and troubleshooting - included free with every purchase
How It Works
The HC-89 Interrupt Sensor operates on the transmissive photointerrupter principle. One side of the U-shaped slot contains an infrared LED that continuously emits an IR beam. Directly opposite, a phototransistor
