Automotive Relays

Automotive relays are switching devices used in the automotive industry for applications such as ignition and fuel injection systems, power steering systems, and power door locks. They are also used for controlling current flow and providing signal paths to control an automobile’s electrical system. The CB1A-R-WM-12V automotive relay is a general purpose relay used for automotive applications.

A relay is an electrically operated switch that opens and closes circuits, similar to a mechanical switch. It is used to control the flow of electrical energy in a circuit. Relays are used to control circuits with higher electrical current or higher voltage than can be controlled by switches or electrical devices. The CB1A-R-WM-12V is a small, lightweight, and reliable automotive relay.

The CB1A-R-WM-12V is a double pole, double throw (DPDT) relay, meaning it has two sets of contacts, each used for connecting two different circuits. Its two NO (normally open) contacts are connected to the two common pins on the relay, and its two NC (normally closed) contacts are connected to the two normally closed pins on the relay. It requires a 12V DC power supply, and has a power rating of 10A and a maximum voltage of 12V DC. It is UL (Underwriter’s Laboratory) and CSA (Canadian Standards Association) certified. The relay has an operating temperature range of -40˚C to +85˚C and a storage temperature range of -40˚C to +125˚C.

The CB1A-R-WM-12V is commonly used in automotive applications such as ignition and fuel injection systems, power steering systems, power door locks, and other control systems. It is designed to be easily mounted on a variety of surfaces and is suitable for use in harsh environments such as outdoor applications, automotive engines, and under-hood applications. Its small size makes it ideal for use in tight spaces.

The relay works on the principle of electromagnetism. When a current flows through a coil, it generates an electromagnetic field. This electromagnetic field is used to create a mechanical force that moves a plunger, which in turn, moves the contacts in the relay from their normal open or closed positions. When the coil is energized, the internal switch in the relay is closed, allowing the current to flow through the relay. The internal switch is automatically opened when the coil is de-energized.

The CB1A-R-WM-12V is a reliable and durable automotive relay that is suitable for a wide range of automotive applications. It is easy to install, and its small size makes it ideal for use in tight spaces. It works on the principle of electromagnetism and is certified by both UL and CSA.
