Automotive relays are essential components of cars that allow for the switching of electrical current in and out of the car’s circuits. A CA1A-12V-N-5 relay is a 5-pin configuration, sealed, momentary, single-pole, normally open (SPNO) relay that is used mainly in automotive applications.The 5 pins that make up the CA1A-12V-N-5 relay are the terminal contacts, which comprise two coil pins (85 and 86) and three contacts (30, 87a, and 87). When the coil pins, 85 and 86, are energized, an armature inside the coil magnetizes, drawing in the contact arm and discharging the contact between 87a and 30. This creates an open circuit from 30 to 87a. When the coil pins, 85 and 86, are de-energized, the armature depolarizes, and the contact arm is discharged, allowing the contact between 87a and 30 to close, creating a full circuit in between the two points.The CA1A-12V-N-5 is designed to handle a voltage of up to 12 volts, making it perfect for the low-voltage requirements of most automotive relays. Furthermore, the sealed construction of the relay gives it a high degree of protection against dust and dirt, as well as making it immune to vibration and shock. This makes the CA1A-12V-N-5 suitable for automotive applications including the control of cooling fans, starting systems, headlights, and other electrical components.The CA1A-12V-N-5 is a momentary relay, meaning that it only closes for as long as the coil pins, 85 and 86, are energized. This allows for a more flexible approach to controlling electrical components. For instance, a CA1A-12V-N-5 could be used to switch headlights from low to high beam for a short period of time without having to manually switch them back.In summary, the CA1A-12V-N-5 is an automotive relay with a 5-pin configuration, sealed construction, and a voltage rating of up to 12 volts. Its momentary SPNO configuration makes it perfectly suited for controlling automotive components such as cooling fans, starting systems, and headlights. With its high durability and resistance to dust and dirt, the CA1A-12V-N-5 is a reliable and affordable solution for automotive applications.
