Signal Relays, Up to 2 Amps2-1393817-4 relays are among the most used switch relays in the electrical engineering and automation industry. Their compact size and low cost, combined with reliable performance, make them a popular choice for many applications. These relays are designed for use in low voltage control systems and are rated up to 2 amps.2-1393817-4 relays feature two sets of contacts; one sealed from the outside environment (the NO contacts) and the other exposed to the outside environment (the NC contacts). The NO contacts are normally closed (NC) while the NC contacts are normally open (NO). The two contact sets can be either a Form A (NO and NC contact sets sharing the same common connection) or a Form C (NC and NO contact sets sharing the same common).The working principle of a 2-1393817-4 relay is based on an electromagnet, which creates a magnetic field when current is applied to it. This magnetic field activates the contact sets. When the current is removed, the contacts are released, depending on the contact type (NO or NC). The 2-1393817-4 relays are mainly used as interfacing relays in low voltage control systems. Due to their low cost and high reliability, they are widely used to isolate sensitive control circuits or devices from the hazardous environment, thereby preventing accidental damages due to current leakage. These relays are also used as controlling relays by application of appropriate controls and ratings.Applications of 2-1393817-4 relays are found in many industrial and home electrical systems. They are used in controlling the on/off operation of electrical circuits such as motors, heaters, and air conditioning systems. In complex systems, they are used as interfacing devices to control and monitor the flow of current from one circuit to another.In the automotive industry, 2-1393817-4 relays are used as switching and control relays in various systems. They are used to control the activation of airbags and other safety systems, and to control the operation of fuel pumps and oxygen sensors in cars. In the home, these relays are used to control the on and off operation of electric lights, fans, and other electrical appliances.In summary, the 2-1393817-4 relays provide reliable, safe, and economical operation in low voltage control systems. Their small size and low cost make them ideal for applications in industries, automobiles, and the home. With appropriate controls, they can be used as controlling relays and as interfacing relays in various applications.
