HFW1131K00

Signal relays are electrically operated switches used to control, or actuate, a circuit of much higher current. They are used in control circuits, such as in automated manufacturing operations to control machines and processes. Signal relays are used when a small electric signal is to control either an electric motor, lamp, or other electronic or electrical control system.

The HFW1131K00 signal relays, with up to 2 amps capability, are among the most reliable and flexible relays in the market. These small but powerful relays are designed with a balanced construction for low voltage drop and long life and superior contact protection.

The HFW1131K00 signal relays use a bimetal switch armature, which is sensitive to thermal changes in its environment. This change in temperature affects the resistance characteristics of the relay, resulting in an increase or decrease in voltage, which in turn will cause the relay to operate. Thus, voltage and temperature changes are the key elements of a signal relay.

The HFW1131K00 signal relay can be used in a variety of applications, such as car alarms, security systems, and automatic door openers. Its small size and powerful operations make it an ideal choice for controlling low-amperage circuits. The signal relay can also be used as a safety device to protect low-amperage circuits from overloads and surges. It can also be used in industrial automation systems, to control motors, lights, switches, and other electrical equipment.

The working principle of the HFW1131K00 signal relay is simple yet effective. When the load current passes through the relay, the MOV (metal oxide varistor) will begin to work and, due to its highly efficient temperature coefficient, it will start to reduce the voltage flowing through the relay. This reduced voltage will cause the relay to switch off and the load will be disconnected. This process of switching off happens very quickly and can be repeated as needed, thus providing a reliable solution for a wide variety of applications.

In conclusion, the HFW1131K00 signal relays, with up to 2 Amps capability, are among the best, most reliable and flexible relays in the market. With its bimetal switch armature and efficient temperature coefficient, it is ideal for low-current applications in automation, security, and automotive markets. Whether it is controlling a motor, switching on a light, or simply disconnecting electrical equipment, the HFW1131K00 relay is a perfect choice for the job.
