Frequently Asked Questions
When choosing the right D-subminiature connector , there are a variety of factors to take into consideration, including operating conditions, housing materials, and pin type. All of these aspects will affect and enable the right configuration for your chosen application.
D-Subs were once heavily used in home computing, printer cables, computer game controllers, external floppy disk drives, network ports and multi-channel audio recording systems，they are now predominantly used in industrial, aerospace, military, transportation and medical diagnostics because they are extremely rugged, small enough to fit into tight spaces, have a very long-life cycle and can withstand being exposed to harsh environments.
D-Subs are being utilised less on modern devices like laptops, monitors and televisions where physical depth and weight are important to the user. D-Sub connectors take much longer to plug in and unplug due to their size and termination, unlike USB and HDMI connectors.The advantages of D-Sub Connectors are they are extremely rugged and can be used in harsh environments. They are small enough to fit into tight spaces and have a long-life cycle. They are diverse and work well within many different industries .
Male and female D-sub connectors refer to the two different types of connectors that mate with each other. A male connector has pins that protrude from its body and are designed to fit into the corresponding sockets of a female connector. Conversely, a female connector has sockets that accept the pins of a male connector. When connecting two devices, one would typically have a male D-sub connector, and the other would have a female D-sub connector to establish a secure and reliable connection.
D-sub connectors are not typically designed for high-speed data transmission. Their original purpose was for low to moderate-speed signal transmission, such as serial and parallel communication. However, there are variants of D-sub connectors, such as high-density (HD) connectors, which can support higher frequencies and data rates. These connectors have a more compact design and additional shielding, allowing for improved performance at higher speeds.
A gender changer or adapter for D-sub connectors is a small device that allows you to change the gender of the connector. For example, if you have two male D-sub connectors that need to be connected, you can use a female-to-female gender changer to join them together. Gender changers are useful when you need to connect devices that have the same type of D-sub connector but different genders.
The primary difference between a standard D-sub connector and a high-density (HD) D-sub connector is the pin density. HD D-sub connectors have a higher pin density, meaning they can accommodate more pins in the same-sized connector shell compared to standard D-sub connectors. This allows for more compact designs and increased functionality in devices where space is limited. HD D-sub connectors often have additional rows of pins or sockets, providing more options for signal transmission.
When soldering D-sub connectors, there are a few considerations to keep in mind. First, ensure that you have the correct pin assignment and orientation before soldering. Double-check the wiring diagram or pinout information to ensure accurate connections. Additionally, it is essential to use the correct tools and techniques for soldering, including a temperature-controlled soldering iron and the appropriate solder. Avoid applying excessive heat for extended periods to prevent damage to the connector or nearby components. Lastly, it’s important to follow proper safety precautions and work in a well-ventilated area to avoid inhaling fumes from the soldering process.
D-sub connectors are not typically designed for high-power applications. They are primarily intended for low to moderate power levels, focusing on data and signal transmission rather than power delivery. If you need to connect devices that require high-power connections, it is advisable to use connectors specifically designed for high-current applications..
A circular connector is a cylindrical, multi-pin electrical connector that contains contacts that power electrical devices, transmit data, or transmit electrical signals. A circular connector is designed to withstand harsh environments and reliably deliver data.
An electrical connector is an electromechanical device used to create an electrical connection between parts of an electrical circuit, or between different electrical circuits, thereby joining them into a larger circuit.
Circular connectors are most often (but not always) connected by threaded areas on the shells. This screw-in connection allows them to be easily and securely locked into position and remain in place despite vibration or impact. Other types of connection systems include bayonet locking, push/pull locking, and snap lock.
Improved Reliability: M12 connectors are made with strong and long-lasting materials, so they are very resistant to vibrations, shocks, and environmental factors like dust, wetness, and changes in temperature.
M12 connectors can be securely attached by soldering, securing with vertical through holes, or right-angle connectors. They are built to withstand environmental stresses and to be waterproof, making them ideal for heavy-duty applications.
They contain multiple pins, or contacts that connect with applicable parts to transfer electrical power, signals, or data. They may also be referred to as circular interconnects. The internal contacts are mated with wire or cable to carry a signal.
In most cases, D-sub connectors are not designed for hot-plugging or hot-swapping. Hot-plugging refers to the act of connecting or disconnecting a connector while the devices are powered on, while hot-swapping refers to the act of replacing a connector while the system is operational. D-sub connectors are meant to be connected or disconnected when the devices are powered off to ensure proper signal integrity and prevent damage to the devices or the connector itself. However, there may be specific applications or devices that support hot-plugging or hot-swapping with D-sub connectors, so it’s important to consult the device’s documentation or specifications to determine if it is possible.
D-sub connectors are not designed for high-temperature environments. The plastic or metal materials used in their construction may not be able to withstand extreme temperatures. If you need to use connectors in high-temperature applications, it is important to select connectors specifically designed for such conditions, such as connectors with high-temperature-rated materials or connectors compliant with industry standards for high-temperature environments.
While D-sub connectors are suitable for many indoor applications, they may not be ideal for outdoor or harsh environments without additional protection. D-sub connectors are not typically designed to be weatherproof or resistant to dust, moisture, or other environmental factors. However, there are D-sub connector variants available with environmental sealing options, such as gaskets or O-rings, that provide better protection against moisture and dust ingress. Additionally, there are ruggedized D-sub connectors designed to withstand harsh conditions, including high vibrations or mechanical stress. These ruggedized connectors often feature enhanced shielding and robust construction to ensure reliable performance in demanding environments.
The original D-sub connectors are now defined by an international standard, IEC 60807-3 / DIN 41652. The United States military also maintains another specification for D-subminiature connectors, the MIL-DTL-24308 standard.
PC input generally involves one of the following five interface types: D-Sub for analog connections; DVI-D for digital connections; DVI-I, which is compatible with both analog and digital connections; and HDMI and DisplayPort, representing the new generation of interfaces for digital connections.
Mount D-Sub connector from inside of panel or enclosure using hex jack screws . Mate connectors and secure backshell thumbscrews to threaded jackscrews. Waterproof IP67 rating is achieved by gaskets / seals in backshell and silicone seal ring in connector.
D-subminiature or D-sub connectors were introduced by Cannon in 1952. They were ubiquitous in computer applications from the 1960s to the early 21st century and are still in widespread use in industrial applications. Many data communication standards specify D-sub connectors.
D-sub connectors come rated for a variety of voltages. Some D-sub connectors are safely rated to carry up to 1800VAC through each contact.
D-sub has some advantages in compatibility and transmission distance, especially for some old devices and users with special needs. However, under the requirements of modern digital signal transmission, HDMI is more in line with current and future multimedia device connection standards.
Compared with the resistance inside the conductor, the contact resistance is not only higher in magnitude, but also has different properties. For example, under ideal conditions, the resistance inside a conductor is constant, when the voltage decreases, the current also decreases proportionally.
The M16 connection system presents a picture of strength. These connectors combine high performance with low space requirement. That’s why they are so popular with users. M16 connectors are locked with the EURO-LOCK-SYSTEM. The TWINTUS series is a distinctive feature of this product line.
Circular is ideal for single-use low-power connection points, while rectangular connectors are perfect for high-power or multi-use connection. For some applications, each connection point needs to be separate.
Circular connectors are cylindrical electrical devices of varying size with circular mating surfaces. They contain multiple pins, or contacts that connect with applicable parts to transfer electrical power, signals, or data. They may also be referred to as circular interconnects.
