Overview
The GP2D061 is a compact infrared distance measuring sensor developed by Sharp Corporation. It belongs to the GP2D series of proximity sensors widely adopted in industrial and consumer applications since the early 2000s. The module integrates an infrared emitter and position sensitive detector (PSD) to calculate distance based on triangulation principles. As a mature product in the sensor market, the GP2D061 has become a standard choice for applications requiring reliable short-range distance measurement. Its analog voltage output simplifies integration with various control systems, while the consistent performance across production batches makes it a dependable component for OEM manufacturers.
Structure and Working Principle
The GP2D061 consists of three main components: an infrared LED emitter, a precision lens system, and a PSD (Position Sensitive Device). The emitter projects an infrared beam that reflects off the target object and returns through the lens to the PSD. The position where the reflected light hits the PSD correlates directly with the distance to the object. The sensor's internal circuitry processes this positional data and outputs a corresponding analog voltage between 0V and 3V. This output is typically linear with distance within the sensor's specified range of 10cm to 80cm. The entire measurement process occurs without physical contact, making the sensor ideal for applications where mechanical wear must be minimized.
Key Features
The GP2D061 stands out for its combination of precision and simplicity. It offers 0.1mm resolution capability within its operational range, though environmental factors may affect absolute accuracy. The compact 29.5mm × 13mm × 13.5mm package allows integration into space-constrained designs. Notable features include low power consumption (typically 33mA during operation), temperature compensation circuitry for stable performance across varying environments, and inherent resistance to visible light interference. The sensor's response time of approximately 39ms makes it suitable for dynamic measurement applications in automated systems.
Application Areas
Industrial automation represents the primary application domain for the GP2D061, where it serves in conveyor belt object detection, robotic arm positioning, and assembly line quality control. The sensor's reliability and moderate cost make it particularly popular in small to medium-sized automation projects. In consumer electronics, the GP2D061 finds use in robotic vacuum cleaners for obstacle detection, automatic soap dispensers for hand presence sensing, and smart furniture for position adjustments. Educational robotics kits frequently incorporate this sensor due to its straightforward interface and predictable performance characteristics.
Maintenance and Precautions
Proper maintenance of GP2D061 sensors involves periodic lens cleaning to prevent dust accumulation that could affect measurement accuracy. The plastic housing should be protected from chemical exposure that might cloud the infrared-transparent window. Critical precautions include avoiding operation in environments with strong infrared interference sources (such as direct sunlight or other IR sensors), ensuring stable power supply within the specified 4.5V to 5.5V range, and calibrating for the specific reflectance properties of target objects. The sensor performs optimally with matte surfaces and may require adjustment for highly reflective or absorbent materials.
B2B Procurement Guide
When procuring GP2D061 sensors in bulk, verify the manufacturer's quality control processes for consistent output characteristics across units. Many industrial buyers opt for pre-calibrated batches to minimize on-site adjustment requirements. Lead times typically range from 4-8 weeks for standard orders, though some distributors maintain regional stock. Consider purchasing evaluation boards or development kits for initial testing. For high-volume applications, discuss custom packaging options to streamline assembly line integration. Technical support availability from the supplier can significantly impact implementation efficiency.
