Circular Connectors

Circular connectors are versatile components that provide secure connections in commercial, industrial, and aerospace applications. Because of their circular housing, these connectors are easy to mate and sturdy in performance, sending power, signal, and data in environments that demand high durability. With many contact positions, connectors of this sort are suited to systems that have a variety of efficient and reliable communication pathways.

Constructed to survive harsh environments, round connectors can take quite a lot of punishment without giving up any electrical signal—they're built to resist vibration, shock, and extremes of temperature. These are the working conditions that often exist in our outdoor communications, industrial machinery, and transportation circuits. Yet even with all this ruggedness, many round connectors rightfully deserve the name "circular"; that is, they are not only space-efficient but also well-suited for many applications in which a connector can and should not be frontally bulked up.

More Information about Circular Connectors

The many forms of circular connectors make them suitable for countless applications found in the automation, medical, and many other industries. They seem commonplace, yet their customizability makes them something of a black box. Inside the black box are various features. The first is the contact arrangement. Next is the housing. Finally, the exterior is customizable, too. You can choose from several materials and sealing options. And where you find additional solutions, such as for PCB connections, you will also find these counting the ways to provide reliable service as a final act.

FAQs

Are circular connectors designed for the temperature range found in robotics?

Yes, circular connectors are designed to operate within the temperature range commonly found in robotics, ensuring reliable performance in high-heat and low-temperature environments.

Serial Communication Basics

In telecommunications, the process of sending data sequentially over a computer bus or communication cable is known as serial communication. Serial communication transmits data one bit at a time. Parallel communication transmits bits simultaneously over multiple communication lines in a single bus or cable. While it may seem that parallel communication would be the preferred method, this is not true in many situations. 

Because of the increased complexity and data transmission, serial communication has faster speeds than parallel communication. The speed at which serial is communicated can be altered by adjusting what is known as the BOD rate, which simply increases the number of the bits that can be transmitted per second. This is one of the reasons serial communication methods have remained such a common method for basic communication in much of computer based hardware used today. 

Some of the most common standards that have been created to take advantage of serial based communication in the industrial space would be RS 232 and RS 485. The earlier RS 232 standard was very common in computing in many different industrial, commercial and residential applications. It had lower transmission speeds, short maximum cable lengths and large voltage swings, making it useful only in certain situations. RS 485 is an improved standard that is still found in many of the same applications today. It resolved many of the issues the earlier RS 232 standard had by allowing longer cable lengths, higher transmission speeds and other improvements that increased its usability and performance.
