Because of the wide variety of current electronic connector models and specifications, many customers hit a wall in the stage of selecting electronic connectors. In response to this problem, Renhotec connector engineers mainly explain the five point that need to be clear while choosing the connector, I hope to help you solve the problem of connector selection.
The connection method of the electronic connector is the primary issue in the selection, because the connection method of the connector for different purposes is different.
The selection of electronic connectors needs to consider electrical performance requirements, because the current carrying capacity of electronic connectors is determined by the needs.
The shape, structure and space design of the electronic connector affect the entire connector product, such as the distance between the connector and the size and height requirements. This problem needs to be strictly handled in the selection stage.
The selection of electronic connectors should also consider the application environment, and meet the harsh environment such as temperature, humidity, vibration and corrosion resistance as much as possible.
One of the selection requirements of electronic connectors is its sealing performance, because in some special conditions, it may need to be sealed for a long time to reduce the intrusion of moisture, and it has high-quality waterproof performance.
Above are the five requirements that need to be clear in the selection of electronic connectors .

Professional d-sub apply to PCB ,LED,and all sorts of equipment.It is divided into Density D-sub ,Power D-sub,Coaxial D-sub ,Waterproof D-sub . D-sub accessories and Other D-Sub (like Dual Port, Filter, Special Layout) we have it!Renhotec offers a complete line of standard and custom D-Subminiature connectors in both vertical and right angle, solder and press fit.
D- sub connectors are widely used in industrial applications worldwide.Structural standards,easy for installation .It's on the computer and so many many aspects.
D-sub connectors were arguably the first and most widely established In/Out (I/O) interface connector and are so called because of their trapezoidal (vaguely “D” shaped) shell which provides mechanical protection, shielding and an inbuilt polarisation when mating male to female, whether cable-end or panel mounted.
They’re still amazingly popular in control and instrumentation; audio, communications and I/O from Printed Circuit Board applications.
There is a steel shell in the common Dsub connector, normally plated with nickel or tin although for anti-magnetic applications the base material may be brass and Stainless Steel shell versions are also built.
The shell / housing /cover on the male dsub connectors is normally “dimpled” to create good electrical continuity with the mating female, thus ensuring EMI/RFI shielding if screened cables have been terminated to the shell. D-subminiature connectors are available in five standard shell sizes: 9, 15, 25, 37,50,104 way plus High Density versions with 15, 26, 44, 62 or 78 contacts. The dimensions of dsub connectors are generally in accordance with IEC 60807-2 (was DIN 41652), BS9523 F0018, MIL-C-24308 and satisfy IEC Recommendation 48B; because of this they are compatible and interchangeable acoss manufacturers.
D-sub connector with structural Criterion ,beautiful appearance,easy to install,meet a lot of criteria.

USB, short for Universal Serial Bus, is an industry standard developed in the mid-1990s that defines the cables, connectors and communications protocols used in a bus for connection, communication, and power supply between computersand electronic devices.It is currently developed by the USB Implementers Forum (USB IF).It mainly has three series ,usb2.0/3.0/3.1,connector type has A type,B type, Mini A/B,Micro usb connector A/B ,C type.Above all Mini type is seldom used.
USB was designed to standardize the connection of computer peripherals (including keyboards, pointing devices, digital cameras, printers, portable media players, disk drives and network adapters) to personal computers, both to communicate and to supply electric power. It has become commonplace on other devices, such as smartphones, PDAs and video game consoles,psp usb cables,etc. USB has effectively replaced a variety of earlier interfaces, such as parallel ports, as well as separatepower chargers for portable devices.
The newly type c usb connectors,are designed to an industry standard that provides a sleek,slim design small enough for handheld devices and robust enough for industrial applications.The USB Type-C connector features reversible mating interface; the receptacle is designed to accept a plug in any direction, enabling easy, reliable mating. This connector supports a variety of diff erent protocols, and with the use of adaptors, it is backwards compatible to HDMI, VGA, DisplayPort, and other types of connections from the single USB Type-C port. We provide a distinctive electromagnetic interference (EMI) design on the back of the receptacle shell to help eliminate unwanted EMI leakage, as well as enhanced retention features, waterproof and splash proof options for better performance in rugged environments.
USB type A connector usually used in perconal computers,it’s the most widely used usb connectors.
USB type B connectors usually used for 3.5inch Mobile HD,printer machine and displayer.
Mini USB usually used for digital camera,digital video,Measuring instrument and disk enclosure.
Micro USB is the most common usb connector which is widely used in our mobilephone connectors.
RENHOTEC GROUP, Chinese RJ45 connector manufacturer for more than 12 years with ISO certified. We have rich experience in OEM and could provide suitable project plan with competitive price for customer. Now ,Let’s us introduce some knowledge of the RJ45 connectors.
RJ45 is a kind of information socket(communication terminal)connector in the wiring system, which is consists of a plug(connector, crystal head) and a socket(module).The plug has 8positions and 8 contacts. RJ is an abbreviation for Registered Jack, meaning "registered socket".In the FCC (United States Federal Communications Commission Standards and Regulations), RJ is the interface of the public telecommunication network,and the RJ45 of the computer network is the common name of the standard 8-bit modular interface.
RJ45 connector has 8 pins, which means an RJ45 cable contains 8 separate wires.You can see the eight different color wires, If you look closely at the end of an Ethernet cable. Four of them are striped, and the other four are solid colors . Usually, for the RJ series products, we can see xPyC, so what is it? Here below you can get the meanings:
P = Positions C = Contacts
x = number of available Positions for Contacts which is the physical SIZE of the connector.
y = number of Contacts installed in the above size and the number of conductors in the cable.
For example:
1.6P6C is a 6 Position with 6 Contacts and wires. This also goes by the name RJ11
2..8P8C is a 8 Position with 8 Contacts and wires. This also goes by the name RJ45.
Category
The RJ series are basically named on the FCC standards and regulations. The numbers following the RJ represent the number of wires. Normally ,the RJ series have these kinds of types:
RJ11, RJ14, RJ25 telephone line interface (respectively for a pair, two pairs, three pairs),RJ45 Ethernet interface (network interface).
More classification as below:
1.Gender: Female/Male
2.Orientation: Vertical/Straight/180 degree/Side entry Right Angle/90 degree/45 Degree
3.Terminal Type:Through-hole（DIP)/SMT Type
4.Port:Single Port/Muti-port:for example:1×1,1×2,1×4,1x6,1x8/2×1,2×2,2×3,2×6
5.Function:Shielded/Unshielded, and the shield has full metal shielded and half-cover shielded,which is with shrapnel or not.
6.With/without leds
7.With transformer/Magnetic or without
Wiring
RJ45 can be wired the cables in two different ways. One is named T-568A ,and the other is T-568B. The T-568B wiring scheme is the most common, but many devices support the T-568A wiring scheme as well. Some networking applications need a crossover Ethernet cable, which has a T-568A connector on the one end and on the other for a T-568B connector. This kind of cable is regular used for direct computer-to-computer connections when there is no router, hub, or switch available.
These 2 wiring standards are listed below:
| T-568A
1. White/Green (Receive +) 2. Green (Receive -) 3. White/Orange (Transmit +) 4. Blue 5. White/Blue 6. Orange (Transmit -) 7. White/Brown 8. Brown |
T-568B
1. White/Orange (Transmit +) 2. Orange (Transmit -) 3. White/Green (Receive +) 4. Blue 5. White/Blue 6. Green (Receive -) 7. White/Brown 8. Brown |
Application
RJ series connectors are widely used in civil, industrial, medical, communications and other fields.In the Civilian areas, such as: telephone, network adapter, PC Notebook,Router/Switch, Wireless Router,Hubs, printers, security cameras, game consoles and other devices.
