Terminal Blocks – Accessories: 260A49-28 Application Field And Working Principle

Terminal blocks are an integral part of the electrical control industry. They are used to join two or more electric and electronic components together, thereby providing a way of distributing input and output signals. Terminal blocks come in a variety of sizes and shapes depending on their particular application needs. 260A49-28 is one of the many types of terminal blocks from the manufacturer Hubbell. It is perfect for applications that require miniature designs where space is a prime consideration- such as telecommunications and process control. The 260A49-28 has a built-in heat sink which helps to dissipate heat rapidly from the wired terminals. It also comes with a terminal shorting bar which offers an additional advantage of having direct voltage and current bussing. In terms of application field, one of the major areas of use for the type of terminal blocks is industrial control systems. Industrial control systems are used for managing and controlling machines and industrial processes as well as for monitoring them. Because of their adaptability, 260A49-28 terminal blocks can be used in applications covering the monitoring and control of a wide range of industrial processes, from general logistics to micro-level automation systems. The choice of materials used in creating these terminal blocks makes them suitable for a range of different applications. They are constructed from a polypropylene base with a steel structure for temperature control, plus heavy duty brass screws and nuts. All of these combine to create an excellent impact and corrosion resistance at temperatures up to 85 °C. On top of being suitable for harsh environments, the 260A49-28 terminal blocks are also dust- and water-proof. This makes them ideal for use in high-humidity environments and helps ensure a more reliable and safe connection. In terms of working principles, the 260A49-28 terminal blocks operate on an open-button principle, meaning that the contacts made by the two parts of the terminal block form a connection when depressed. This action compresses the contact surfaces of the male and female parts of the terminal block together, resulting in a reliable and secure connection between them. The presence of a built-in pressure port also helps ensure that the contact pressure is maintained while the terminal block is in operation.The design of the 260A49-28 terminal blocks also incorporates a screw-locking mechanism which requires a single hex wrench for release. This prevents accidental opening of the connection while it’s in operation, ensuring a secure connection over a period of time. In conclusion, the Hubbell 260A49-28 terminal block is an excellent choice for applications which require miniature designs, are dust and water-proof, and have excellent corrosion and temperature-resistance properties. It works on an open-button principle and is secured through a screw-locking mechanism, ensuring reliable and safe connections.
