Reed relays are types of electromagnetic relays used for switching an electrical circuit on and off, typically using an electrical signal that is applied to the coil of the relay, activating a magnet inside the relay. The DAR72410TU, built by Fujitsu, is a member of the double-throw reed relay family. Its unique construction allows for maximum power handling and low turn-on voltage for reliable switching performance at higher operating voltages. The relay itself consists of two reed contacts, a double wound coil, and an encasing plastic body. The DAR72410TU is designed for a variety of applications from telecom, medical, industrial, & distributed control systems. It is primarily used for signal control and the switching of data, current, and voltage sources. Due to its mechanical design, the DAR72410TU features ultra low static power consumption and a quick turn-on time of 1.5ms. Additionally, the relay also provides excellent insulation characteristics. In terms of operating principle, the DAR72410TU works when a voltage is applied to its winding. This voltage then energizes the reed contacts causing them to be attracted by the electromagnet. Until the voltage is applied, the reed contacts remain in the de-energized state. When the voltage is applied, the two inner reed contacts, which are mounted to the outer layer, snap close. This forms a connection between the two circuits and closes the circuit. Then, when the second voltage is applied, the connection between the inner contacts and the outer layer is broken, and the outer contacts are closed, completing the cycle. The DAR72410TU offers a wide range of features that make it suitable for use in a wide variety of applications. These include a wide operating temperature range, a well-defined contact structure for consistent performance, a highly reliable insulated case, excellent noise immunity characteristics, and an efficient operation through low contact resistance. The DAR72410TU reed relay also features a pre-designed release mechanism that provides for both low and high operations. This allows users to operate their relays with a short circuit current, which makes it suitable for use in circuits with higher current ratings. In conclusion, the DAR72410TU is a highly reliable and efficient double-throw reed relay suitable for a range of applications. Its unique features of ultra low static power, 1.5ms turn-on time, and excellent insulation characteristics make it suitable for telecom, medical, industrial, and distributed control systems.
