1. Size and shape
MDR (Mini D-sub): MDR is a smaller D-sub connector, usually used in space-constrained applications. Its compact appearance is suitable for small devices and installation spaces.
SDR (Sub D-sub): SDR is a standard-sized D-sub connector with a larger size, suitable for occasions that require more connection pins or higher current.
2. Number of pins
MDR: Usually has a smaller number of pins, suitable for simple data transmission needs.
SDR: Can provide more pin options, suitable for complex signal transmission needs, such as multi-channel video and data streams.
3. Application scenarios
MDR: Widely used in small industrial cameras and equipment, suitable for environments with limited space.
SDR: More common in large equipment and systems, can carry more functions and signals, suitable for more complex industrial applications.
4. Electrical performance
MDR: Usually inferior in electrical performance, suitable for transmitting lower bandwidth data.
SDR: Designed to support higher bandwidth and data rates, suitable for occasions requiring high-performance transmission.
