Terminal Blocks - Accessories - Jumpers

Jumpers are a type of terminal block accessories that are broadly used in industrial and commercial electrical applications where machines, programming and control devices need to be connected in a variety of ways. The important role of jumpers lies in their ability to isolate and transfer signals between multiple points on a circuit. There are several types of jumpers available and the type that is used is largely dependent on the application.

Jumpers are generally designed with a length of metallic wire, usually of brass, stainless steel, or other alloyed materials. These wires are usually twisted in a "U" or "S" shape and soldered in place. The jumper wires then connect two terminals of the terminal block with a bridge material often made of teflon, nylon or plastic. The connecting material used is often referred to as an "interconnect". The connection is then held together with a screw which is often flat or of an eyelet shape.

The advantages of using jumpers include their ability to be used with multiple terminal blocks, greater flexibility in connecting multiple components, and reduced footprint. The major disadvantage to using jumpers is that they are susceptible to vibration and shock hazards that can occur in industrial and commercial applications.

Jumpers are a cost effective and convenient way to connect and isolate multiple points on a circuit. They can be used in many types of electrical equipment such as computers, process control systems, automation equipment, PLCs, and in industrial machines. In addition, they are reliable, long lasting, and require minimal maintenance. This makes them an ideal choice for industrial and commercial applications.

The type of jumper selected depends on the application requirements of the user. There are several types of jumpers available in the market, including splicing jumpers, panel mount jumpers, flexible jumpers, rigid screw-on jumpers, terminal strip jumpers, and linkable jumpers. Splicing jumpers are most often used for attaching wires to a circuit board, while panel mount jumpers are designed to be mounted onto walls or panels. Flexible jumpers are excellent for repairing broken connections and allowing for easy wire re-orientation. Rigid screw-on jumpers are used where small connections need to be made to the terminals. Terminal strip jumpers are used to connect multiple terminals together, and linkable jumpers are used in larger multi-terminal connections.

Installation of jumpers is usually done by an experienced technician, as the electrical connections must be done correctly to ensure a safe application. Proper installation practices require the use of proper tools and the appropriate safety equipment. The jumper must be properly secured to the terminal block and the wire connections firmly soldered in place before the terminal block is powered. In some cases, additional safety measures may need to be taken when using jumpers, such as installing a surge protector.

Jumpers are essential components in many electrical applications and should always be installed by those with the proper electrical knowledge and experience. In order to ensure that the application is safe and reliable, it is important to choose the correct type of jumper for the application and follow all installation instructions properly.
