Terminal blocks - Panel Mount are a type of electrical terminal commonly used in a variety of industrial, commercial and residential applications. A Panel Mount Terminal is mounted to a single-channel panel or enclosure and features a cable connection point on the outside of the panel or enclosure. This type of terminal is ideal for installations that require a more permanent connection point and allows for easier wiring without the need to access the interior of the panel or enclosure. It also allows the user to organize and secure wires and cables outside the unit to prevent damage or accidental disconnection.

Panel mount terminal blocks are available in a variety of sizes and configurations, from tiny 5.08mm (APT) terminal blocks to larger 20mm terminal blocks with multiple pole combinations. The most common type of terminal block is the single-pole terminal block, which is specified by its pole number. There are also double-pole, triple-pole and quadruple-pole terminal blocks available. The number of poles will determine the amount of power that can be handled by the terminal block.

Most Panel Mount Terminal blocks feature spring or screw-clamp mechanisms to hold wires and cables in place. Spring-clamp terminal blocks use a spring-loaded pressure to clamp the wires and cables to the contact, while screw-clamp terminal blocks utilize a screw to secure the wires or cables. Most screw-clamp terminals also feature a lockable feature, which prevents accidental disconnection.

Another common feature of Panel Mount Terminal blocks is a base that is made of different materials, such as plastic, metal or wood. The base is used to mount the terminal block to the panel or enclosure, and should be installed in accordance with the manufacturer’s specifications. This will ensure that the terminal block is secured properly and will not come loose or vibrate during operation.

Panel Mount Terminal blocks are commonly used in applications requiring frequent changes to the connection point, such as in panel-mount electrical switches, relays, controllers and meters. They also come in handy for connections to communication and computer systems, sensors and actuators. In any of these applications, installers should ensure that appropriate protective measures are taken to shield the cables and wires from possible shock and short-circuits, as well as other potential sources of current leakage or power surges.

For harsh environments, Panel Mount Terminal blocks are often coated with a special UV-enhanced jacket to provide additional corrosion protection. Additionally, some types of Panel Mount Terminals also come with a special insulation sleeve that helps to provide EMI/RFI protection for sensitive installations. The insulation sleeve also helps to protect the wires and cables from heat build-up caused by prolonged or high current draw applications.

When choosing a Panel Mount Terminal Block to use in applications, it is important to ensure that it is rated for the voltage and current that the application requires. Additionally, installers should ensure that the connection points are securely locked and that the terminal block is securely mounted in the panel or enclosure. Proper maintenance of the terminal block is also important to ensure its longevity and help prevent potential problems.
