OJ7/J

OJ7/J application field and working principle falls under the category of Terminal Blocks - Accessories - Jumpers. OJ7/J jumpers are used as a means of shorting out certain terminals from the base element, such as a switch or relay contact. They are typically connected over two or three pins, enabling a direct connection with either side. OJ7/J jumpers are used mainly in industrial and electrical applications, such as motor control units, panels, and junction boxes.

The most common type of OJ7/J jumpers are dual-pin jumpers. These are used to form a connection between two terminals, typically to provide a connection from one circuit to another. Dual-pin jumpers are constructed of a flat piece of metal with two parallel pins. The pins are inserted into either side of the jumper, and they are connected to form a connection between the two terminals.

Three-pin jumpers are also available and can be used to form connections between three terminals. These jumpers are typically larger than dual-pin jumpers and have three pins rather than two. Similarly, four-pin jumpers can be used for four-terminal applications, such as for four-way switches. Four-pin jumpers are usually constructed of two pairs of pins connected to a single piece of metal. The four parallel pins form a connection between the four terminals.

OJ7/J jumpers are typically constructed of stainless steel or copper. The metal is then covered with an epoxy coating to prevent oxidation and corrosion. The epoxy coating also helps to protect the jumper from moisture and dust. Some OJ7/J jumpers are also constructed of metalized plastic for superior insulation.

The working principle of OJ7/J jumpers is quite simple. An electrical current is sent through the pins of the jumper, and the terminals are shorted out. This allows a direct connection between two circuits without any intervening wires. OJ7/J jumpers are designed to be quick and easy to install, and they provide a reliable connection.

OJ7/J jumpers are used in many different electrical applications, such as within motor control units, relay and control systems, panels, junction boxes, and more. They are also used in industrial and commercial applications, including power distribution systems, light and sound applications, and security systems. OJ7/J jumpers prove to be reliable, durable, and easy to install.
