Mingjiada Supply Infineon REAL3™ Series iToF Image Sensors, Supply VisionICs Series dToF Image Sensors

Shenzhen Mingjiada Electronics Co., Ltd. – With many years of experience in the semiconductor sensing sector, we specialise in the supply of 3D ToF image sensors from stock, model selection, technical support and inventory buyback services. We offer a comprehensive range of dToF and iToF sensors from leading domestic and international brands, covering a full spectrum of applications including consumer electronics, industrial inspection, smart home, automotive sensing and service robots.

3D ToF image sensors are primarily divided into two categories: iToF (indirect Time-of-Flight) sensors and dToF (direct Time-of-Flight) sensors. Product details are as follows:

1. iToF (Indirect Time-of-Flight) Image Sensors
iToF sensors modulate the light source to emit signals and calculate depth and distance by analysing the phase difference of the reflected light. They feature high frame rates, uniform imaging, controllable costs and high integration, making them suitable for consumer-grade devices requiring short-range, wide-area coverage and mass production. They are primarily used in 3D facial recognition, smart home motion-sensing devices, robotic vacuum cleaners, mobile phone depth-of-field photography, smart bathroom sensors, and industrial object ranging, making them the most widely used 3D vision sensors in the consumer electronics sector.
2. dToF Direct Time-of-Flight Image Sensors
dToF sensors directly calculate the time-of-flight of photons to determine distance. They offer exceptional resistance to ambient light interference, higher measurement accuracy and a wider measurement range. They are suitable for complex outdoor environments, industrial settings with intense lighting and dynamic in-vehicle scenarios, with stability far exceeding that of traditional iToF sensors. They are commonly used in advanced industrial and automotive applications such as autonomous driving perception, high-precision industrial inspection, outdoor robot distance measurement, smart warehouse positioning and high-end security surveillance.

Overview of Mingjiada Electronics’ Core 3D ToF Image Sensor Models:
1. Infineon REAL3™ Series iToF Image Sensors
Infineon’s REAL3™ is a globally renowned series of high-end consumer and industrial ToF sensors. It utilises a fifth-generation 5μm PMD pixel core and features on-chip backlight suppression technology, offering excellent resistance to strong light interference. With a standard operating wavelength of 940nm, it is compatible with mainstream VCSEL light sources and delivers exceptional imaging stability, making it the preferred solution for high-end smart devices. Mingjiada primarily supplies four key models: IRS2877C, IRS2877A, IRS2975C and IRS2976C.
- IRS2877C: A consumer-grade sensor with standard HVGA resolution, optimised pixel layout and balanced power consumption. Suitable for mobile phone autofocus, facial recognition and small smart wearable devices, it offers high mass production stability and outstanding value for money.
- IRS2877A: Based on the IRS2877C, this model features optimised drive algorithms to enhance imaging accuracy in low-light environments. It is suitable for indoor smart home applications, 3D recognition in smart locks, and motion-sensing interaction devices.
- IRS2975C: An industrial-grade model with high stability, flexible resolution scalability and enhanced anti-interference capabilities. It is suitable for object detection on industrial production lines, equipment distance measurement and smart warehouse positioning applications.
- IRS2976C: A high-end automotive-grade ToF sensor, resistant to high temperatures, vibrations and strong light, suitable for in-vehicle short-range sensing, in-car liveness detection and autonomous driving assistance ranging applications.

2. visionICs Series dToF Image Sensors
The visionICs series features high-precision dToF imaging technology, prioritising industrial-grade and outdoor-grade stability, making it perfectly suited to complex operating environments. Mingjiada is the core supplier of three models—VI4310, VI4320 and VI4330—which progressively cover different precision and field-of-view requirements.
- VI4310: A highly integrated entry-level dToF sensor incorporating core ranging and imaging modules. It offers simple commissioning and strong compatibility, making it suitable for small and medium-sized robots and indoor positioning and ranging equipment.
- VI4320: A medium-precision general-purpose sensor with an optimised field of view design and a wider ranging range. It is suitable for industrial assembly line inspection, material identification, and intelligent warehouse sorting equipment.
- VI4330: A high-end, high-precision dToF model with maximum resistance to strong light and dust interference. It supports all-weather outdoor operation and is suitable for demanding scenarios such as outdoor security, short-range perception for autonomous driving, and outdoor inspection robots.
