Reed relays are mainly used to isolate switches and to actuate electrical circuits. The HE722A1220 is a type of reed relay manufactured by Omron Electronics. It is a high-performance, low-cost, single-pole normally-open (SPNO) reed relay that features high reliability and a wide operating temperature range. This relay is well-suited for applications that require frequent switching and long-term reliability, such as home appliances, medical equipment, and telecom systems.The HE722A1220 reed relay consists of a ferrite permanent magnet, an armature, and a switch contact. The armature is a spring-loaded plunger that is placed inside the ferrite magnet and held in the closed position when the magnet is energized. This prevents any electrical current from passing through the switch. When an externally applied DC voltage is applied to the relay, the magnet\'s magnetic field causes the armature to move, thus opening the switch contact. This allows current to flow through the relay. The HE722A1220 can switch between its open and closed states quickly and reliably, making it well-suited for switching high-frequency signals.The HE722A1220 reed relay also features several protection mechanisms that enhance its reliability. It has a built-in protection diode that prevents interference caused by external radio signals. Additionally, the relay\'s design prevents welding of the contact rods when switching rapidly at high power loads. Additionally, the relay\'s design also prevents the contact oxidation that can occur when exposed to high temperatures or humidity.The HE722A1220 reed relay has a wide operating temperature range of -40°C to 130°C. This makes it well-suited for applications that require frequent switching in extreme temperatures, such as in telecom systems, or in medical devices that require a high degree of accuracy and precision. The relay is also highly reliable, with rated life expectancy cycles of up to 1 million. This ensures that the relay is able to withstand repeated switching without degrading over time.Overall, the HE722A1220 reed relay is a highly reliable, low-cost, and high-performance SPNO reed relay. It is well-suited for applications that require frequent switching in extreme temperatures and long-term reliability, such as home appliances, medical devices, and telecom systems. The relay is equipped with several protection mechanisms that further enhance its reliability and makes it suitable for high-frequency switching applications. The HE722A1220 is an excellent choice for any application requiring reliable and rapid switching with long-term reliability.
