![]() ![]() Mostly a USB port has 4 to 24 pins for the transmission of the power and data. We can connect USB connectors to the USB ports in the computer and thus we can transfer digital signals over the USB cables. USB is the short form of universal serial bus, it is used to do short-distance digital communications. We can connect a computer to LAN by using RJ45. These connectors are used to do the connection from a patch panel to a network switch and also it can be used to connect a computer’s NIC to a data port. These connectors are wider than the RJ-11/12 connector which is used in the telephone. RJ stands for registered jack, and mostly it is used for ethernet networking. This is an 8 position 8 conductor modular connector that is mostly used for the data network such as Ethernet. These connectors are mostly held together in a duplex configuration with a plastic clip. The connector body has the squarish shape of the SC connector. ![]() This type of fiber optic connector has a retaining tab mechanism and it is an RJ45 connector. In this type of connector, the ferrule is PC finished to a pre-radius and this would ensure the low back reflection. These connectors are designed with threaded coupling for durable connections. This type of fiber connector is mostly used for telecommunication applications and it provides a nonoptical disconnecting feature. ![]() This type of fiber cable is connected and disconnected by the push-on/pull-on mechanism. This is a subscriber connector and it also has a 2.5mm ferrule to hold a single fiber. Now, these connectors are replaced by smaller and denser connectors. This connector stays in place with a twist-on/twist-off, bayonet-style mechanism. These connectors are used widely for many fiber optic applications. This type of fiber optic connector has a straight tip, this type of connector uses a 2.5mm ferrule it could be a plastic or metal body. This section of the connector would be useful when the connector is attached to another device, this part would hold the connector in place when it is connected to another device. This could be a plastic or metal structure that holds the ferrule This is a thin structure that holds the glass fiber, this would provide a tight grip on the fiber While selecting this connector we must make sure that the impedance of the connector matches the source and load so that maximum power transfer can be achieved. We must choose a coaxial cable according to the impedance, operational frequency, insertion loss, reflection performance, environmental requirements, and also we need to consider the size and cost. These connectors can be used to access circuits, testing, inter-connecting, and also packaging the components into a system. These connectors would provide RF links in communications, and also in the test and measurement field too. The coaxial connectors can be used to connect and disconnect transmission lines, systems, and components at microwave frequencies. What are the major types of connectors used for industrial automation? While selecting a connector we must check its ingress protection rating and by checking this we could determine how the connector would perform for a specified industrial process. It should operate in vacuum conditions too.It should be able to handle extreme conditions like temperature, pressure, shocks, etc. ![]() What are the major requirements for an industrial connector? How to select connectors for industrial applications? We must choose connectors according to our industrial process if the connectors are used where there is a chance for machine vibrations and shock then we should use the connectors that should have a rugged design and it must have a proper casing too. So, in this case, heavy-duty connectors are used. There could be a lot of electronic components in an industrial application and these components would be affected badly if the temperature or the moisture level varies beyond a specified limit. So the connectors which are used in the industry must be able to cope with its environment. The industrial process is carried out by transmitting signals, so connectors are used to transmit signals from cables to industrial equipment or machinery. What is the need for connectors in industrial automation? ![]()
