Triangulation proximity sensor GP2Y0A41SK0F 4 to 30 cm Shortrange laser detector module, replacement for GP2D120XJ00F What this product does Provides reliable shortrange distance sensing using triangulation detection. Measures object distance in the 4 to 30 centimeter range and outputs a proportional analog signal for realtime measurement and control. Designed as a dropin functional replacement for GP2D120XJ00F modules. Key benefits Accurate shortrange detection for tight spaces: effective where precise proximity information is required within a few centimeters to a few dozen centimeters. Easy integration: standard analog output lets the module connect directly to ADCequipped controllers and control systems without complex signal processing. Compact and lightweight: small module footprint fits into embedded systems, robotics, and compact automation equipment. Fast response and stable readings: suitable for dynamic applications that require continuous monitoring and quick feedback. Direct replacement compatibility: intended to GP2D120XJ00F, simplifying upgrades and repairs. Important attributes Function: triangulationbased proximity sensing with analog voltage output correlated to distance. Measurement range: 4 to 30 centimeters. Compatibility: suitable as a functional replacement for GP2D120XJ00F and for use with microcontrollers, development boards, and control electronics that accept analog distance input. Form factor: compact detector module designed for embedded applications and tight mounting locations. Performance: stable, shortrange distance feedback appropriate for obstacle detection, presence sensing, and position monitoring. Typical applications Mobile robotics: obstacle detection and closerange collision avoidance to improve navigation in confined environments. Industrial automation: shortrange part presence detection on conveyors, pick and place alignment, and endofarm tooling proximity checks. Interactive devices and appliances: hand or object proximity sensing for automatic lids, user interfaces, or smallscale automation tasks. Integration notes The module provides an analog distancerelated output that connects to analog inputs on controllers or ADC interfaces. Mount and orient the sensor so the target surface is within the 4 to 30 centimeter range for reliable readings. Use a stable lowvoltage DC supply and common ground when wiring to control electronics. This GP2Y0A41SK0F triangulation proximity sensor is a practical, compact solution when precise shortrange detection and straightforward integration are required, and it serves as a compatible replacement for GP2D120XJ00F modules.
