M23 and M16 Circular connectors are both circular connectors widely used in industrial and automation applications. Despite their similarities, they have some significant differences that make each suitable for specific uses. In this article, we'll discuss the key difference between M23 and M16 Circular connectors.
Size and Pin Configuration
One of the most notable differences between M23 and M16 Circular connectors is their size and pin configuration. M23 connectors have a larger shell diameter of 23mm, while M16 Circular connectors have a 12mm diameter. Due to their larger size, M23 connectors can have more pins, typically 8 to 19, while M16 Circular connectors usually have up to 8 pins.
M23 connectors are designed for high-performance applications that require high voltage and current transmission. They are capable of carrying up to 28A of current and up to 850V of voltage. The larger diameter of the M23 connector shell also allows for a larger cross-sectional area, making it suitable for high current applications. On the other hand, M16 Circular connectors are designed to transmit lower power signals with smaller current and voltage capacities of up to 4A and 250V, respectively.
M23 and M16 Circular connectors also differ in their environmental protection. While both connectors come with IP ratings, M23 connectors provide a higher degree of protection at IP67 or IP68. These ratings indicate that M23 connectors are dust-tight and can withstand temporary submersion in water. M16 Circular connectors, on the other hand, offer a lower rating of IP67 or IP68, indicating protection against dust and temporary immersion of up to one meter.
M23 connectors are commonly used in high-current industrial and automation applications, such as servo motors, high-speed machinery, and industrial robots. M16 Circular connectors, on the other hand, are commonly used in low-current applications, such as sensors, actuators, and fieldbus systems.
Since M23 connectors are designed for high-performance and high-current applications, they are usually more expensive than M16 Circular connectors. M16 Circular connectors are smaller, designed for low-power applications, and are often used in higher volumes, making them a more cost-effective solution.
M23 and M16 Circular connectors have their unique differences that make each suitable for specific uses. M23 connectors are larger, designed for high-current applications, and offer better environmental protection. M16 Circular connectors are smaller, designed for low-current applications, and are cost-effective for high volume usage. Understanding the differences between these two connectors can help you choose the appropriate connector for your industrial and automation applications.
