Infrared Reflection Sensor Modules, 3 Pieces Compact 1channel infrared reflection sensor modules with digital output for reliable noncontact detection. Designed for integration into devices such as electricity meters and fax machines where simple, repeatable presence or position sensing is required. Key benefits Reliable noncontact detection: Infrared reflection sensing detects reflective surfaces without mechanical contact, reducing wear and maintenance compared to switches. Simple digital output: Provides clear 0 and 1 signals for direct reading by control circuits and microcontrollers, simplifying integration and programming. Readytouse module set: Three identical 1channel modules included for multipoint sensing or spare use. Compact and easy to place: Small PCBmounted modules fit into tight enclosures and on control panels where space is limited. Consistent performance across range: Detection reflecting range from 1 mm to 25 mm covers closeproximity sensing tasks for small moving parts or paper. What it does Senses reflected infrared light from nearby surfaces and converts detection into a digital output signal. Outputs logical 0 or 1 to indicate absence or presence of a reflective object within the specified detection range. Provides a straightforward signal for counting, position confirmation, or paper presence detection. Compatibility and integration Designed for use with standard control electronics and common microcontroller platforms used in industrial equipment and office machines. Suitable for retrofit or OEM applications in devices that accept a single digital sensor input. Typical module form factor allows mounting on panels or inside equipment enclosures near moving parts or paper paths. Performance highlights Detection reflecting range: 1 mm to 25 mm for closerange sensing tasks. Output form: Digital logic signal 0 and 1 for clear, binary detection results. Consistent detection behavior when properly aligned and installed within the specified range. Recommended use scenarios Electricity meter pulse detection: Mount the module to detect rotating disk marks or reflective pulses for noncontact pulse counting and monitoring. Fax or printer paper sensing: Use the sensor to confirm paper presence, paper edges, or small media movement inside fax machines and printers. Automation and conveyors: Implement as a simple item detector or position sensor on small conveyor lines, assembly stations, or linefollowing robots where proximity detection up to 25 mm is required. What is included Three 1channel infrared reflection sensor modules with digital output. Installation tips Position the sensor so the target surface is within the 1 mm to 25 mm reflecting range and aligned to reflect infrared light back to the detector. Ensure the sensing surface is reflective enough for infrared detection and avoid excessive ambient infrared sources that may affect detection. Provide a stable mounting surface and secure wiring to prevent movement that can change detection distance. This set of three infrared reflection sensor modules provides a straightforward, compact solution for binary presence and position sensing in meters, office machines, and small automation systems.
