Reed Relays

Reed relays are types of electromechanical relays that consist of a coil and a reed switch. The two contacts of the reed switch are sealed with the relay in an insulating material, often a glass tube. When a current is applied to the coil of the relay, a magnetic field is produced which in turn switches the contacts open or closed depending on the polarity of the circuit.Reed relays are used in a variety of applications and can provide fast, repeatable switching and insensitivity to temperature and vibration. Due to their small size, low power consumption and low cost compared to other types of relays, they are often used in integrated circuits and for the switching of low voltage, low energy signals.One such application field for reed relays is the DAR72410S. This is a double-pole, double-throw (DPDT) reed relay which can show no more than 200mW of power consumption. The DAR72410S features a common part number suffix which helps indicate its specification, such as the rated voltage (V) and the switching current (Iac).The DAR72410S has a nominal voltage of 24 V and is rated for a maximum switching current of 5 A. It has a contact resistance of 800mΩ at room temperature and an insulation resistance of up to 100MΩ. The operating temperature range for the DAR72410S is -40°C to +85°C.The working principle behind the DAR72410S is quite simple. When an alternating current is applied to the relay\'s coil, a magnetic field is created which in turn actuates the reed switch. This causes the switch contacts to open or close, thus initiating a signal to the next component in the circuit.Reed relays are extremely versatile and are used for a range of purposes, including medical sensing, automotive, industrial and consumer electronics, as well as military and aerospace applications.The DAR72410S is designed to be used in applications where exact repeatability and reliability is of utmost importance. It is often utilized in timing circuits and other sensitive applications that must perform reliably without any false triggering. The DAR72410S utilizes a special design which helps dampen the effect of mechanical vibrations, allowing it to remain in the desired position.In conclusion, the DAR72410S is a low voltage, low energy reed relay designed for use in a variety of applications. With its rated voltage of 24V and rated current of 5A, the DAR72410S is perfect for switching low voltage, low energy signals. It is also extremely sensitive to vibration and temperature, making it ideal for applications that must remain reliable in all conditions.
