Reed Relays

Reed relays are small, solid-state relays designed to switch low current DC or AC signals. They are commonly used in many industrial and consumer applications as a means of controlling a signal or as a way to actuate a module or device. Reed relays are reliable and have wide temperature and working environments. They can also be used beside higher powered relay types as an alternative that requires smaller components and lower power requirements.Reed relays come in several main types including the 8L21-24-10 Reed relay. This type of reed relay is used as an environmental protection device in outdoor industrial applications. It is hermetically sealed and is designed to withstand adverse weather conditions, high humidity, temperatures up to 95°C, and vibrations of up to 95 m/s². The 8L21-24-10 relays can also be used to switch signals on both AC and DC circuits.The basic working principle of a reed relay is simple. It consists of a hermetically sealed reed switch that is connected to a lead frame which is placed inside a plastic shell or a PCB terminal. When an electric current is applied to the reed switch, it magnetically operates the switch and actuates the actuator lever. This in turn allows the contact points to close or open depending on the direction of the current. The contact points can then remain in either the open or closed position until the current is removed.The 8L21-24-10 reed relays are usually used in applications such as motor starters, home appliance control, street lighting, LED lighting control, sensing/monitoring applications, and safety interlocks. They are also well suited for controlling small DC motors and other low-medium power DC circuits. Furthermore, the 8L21-24-10 relays are typically used for circuit protection in aircraft or military applications due to their high reliability and wide temperature range.In addition to the 8L21-24-10, there are many other reed relay models that can be used in various scenarios. Some of the more popular models include the 1030, 1060, 10D30, 10L30, and 10V30 reed relays. Each model is designed for specific application requirements and uses a specific operating voltage. The 1030 reed relay, for example, has a maximum voltage rating of 250V AC and a maximum load current of 10A. It can be used in home appliance control applications and LED lighting control applications.Reed relays are suitable for applications where space is limited, and power requirements are low. They are also extremely reliable and provide cost-effective switching solutions in various applications. The 8L21-24-10 reed relays can be used in outdoor as well as indoor environments and are typically used when a low current DC or AC signal needs to be switched. The 8L21-24-10 reed relays provide reliable performance and are designed to withstand extreme temperatures and adverse weather conditions.
