Terminal Blocks - Accessories - Jumpers

Jumpers, also known as terminal blocks, are multipurpose electrical accessories used for connecting two or more circuits together. They are a highly reliable, durable and affordable solution for custom wiring and electrical connection tasks. The 1908990000 application field and working principle can be applied to a wide range of applications including automotive, industrial, robotics, security, power systems, automation and communications. Jumpers are especially useful for connecting two parallel or orthogonal circuits, such as for mounting discrete components onto printed circuit boards, as well as for connecting external wiring to cables, circuit boards, and electrical cabinets.

Jumpers provide a means for connecting two or more separate electrical circuits, one that is wired and one that is to be connected or bypassed. When connected, the jumper allows current to pass between the two circuits. The most common type of jumper used is a dual-pole, double-throw (DPDT) type, which is capable of activating multiple adjacent contacts such as those in a junction box. The working principle of jumpers is based on a simple bridge type arrangement; two electrical terminals (connected together) form the outside of the bridge and a single wire, cable or terminal forms the inside of the bridge. In this arrangement, current is allowed to pass through the jumper between the two terminals, making the connection complete. To disconnect the connection, only the single wire, cable or terminal needs to be disconnected.

Jumpers are generally made out of various materials such as plastic, metal, rubber and others. Most commonly used are copper, aluminum and rubber. Copper and aluminum make up the majority of jumper materials, but other metals like stainless steel and brass can also be used. The material chosen is based on the voltage and type of application the jumper will be used in. When selecting a jumper, the electrical properties, physical shape, resistance, environmental conditions, insulation and other features should all be taken into consideration.

The 1908990000 application field and working principle is used in a variety of electrical and electronic applications. In the automotive industry, jumpers are used to make and break electrical connections between different parts of the vehicle. In industrial applications, jumpers are used to create or cut off power and signals for automated systems. In robotic assemblies, jumpers are used to connect motors, position sensors, and direction control systems. In security systems, jumpers are used to prevent unauthorized access to sensitive areas. In power systems, jumpers are used to connect electrical components like wires, cables and terminals in order to create or maintain power. In automation and communication systems, jumpers are used to create or disable communications and automated processes.

In addition to the 1908990000 application field and working principle, jumpers can also be used for custom wiring and electrical connection tasks. This includes connecting switches or indicators to wires, connecting multiple switches together to suit a particular application, connecting multiple cables or terminals in a single connection, and connecting power sources or ground paths. Jumpers are also used to overcome short circuit problems, or provide bridge connections between wires, circuits, and terminals.Jumper assemblies and accessories are also available in the market, such as terminal blocks, plugs, sockets, isolation switches, earth blocks, surge protection, adapters, and contactors. Terminal blocks provide a secure connection point for multiple conductors to terminate at. Plugs and sockets enable two or more devices to be connected without tangled cables. Isolation switches provide a method of switching power or signals off in a safe and secure manner. Earth blocks provide a secure ground connection point for electromagnetic compatibility (EMC) and surge protection.Jumper assemblies and their accessories play a key role in many electrical and electronic applications. With their 1908990000 application field and working principle in mind, users can conveniently and reliably connect two or more circuits together with a jumper. Their versatility and affordability make them an indispensable tool for custom wiring and electrical connection tasks.
