Reed Relays

Reed relays are a type of electromagnetic switch used to control electric circuits. They consist of a magnetic core with two or more windings of insulated wire wound around it. When current is applied to one of the windings, a magnetic field is created which energizes the switch contacts and causes them to close or open, enabling or disabling the circuit. Reed relays are versatile and economical, and can be used in many different applications.

DBT70510-HR Application Field and Working Principle

The DBT70510-HR reed relay is designed to switch high power AC and DC loads. This device is built with robust construction for long life in industrial applications. It is a latching type relay; the contacts can be held by a permanent magnet without applying power to the coil.

The DBT70510-HR has a coil voltage rating of 5-230V AC/DC and a continuous current rating of 10A at 250V. Its dielectric strength is a maximum of 1500V for a period of 1 minute. The maximum switching frequency is 60 times per minute and the maximum switching power is 2500VA. It has three types of contacts: normally open (NO), normally closed (NC), and changeover (CO). The contact material is silver alloy.

The coil of the DBT70510-HR is driven by an external AC or DC supply, and the contacts are linked to the common, NO, and NC terminals. When the coil is energized, the reed switch is closed, and when it is de-energized, the switch opens. The reed relay contains a strong permanent magnet that helps maintain the contacts even when the coil is not energized. The contact position changes when the coil is energized or de-energized.

The DBT70510-HR is suitable for a wide range of applications such as heating, ventilation, and air conditioning (HVAC) equipment, sensors, motor control circuits, home appliances, and power supplies. The robust construction and high performance of the relay makes it ideal for electrical and electromechanical applications involving high power switching. The latching feature also makes it suitable for applications that need to maintain a fixed position.

Conclusion

The DBT70510-HR reed relay is a high performance and robust device suitable for controlling high power AC and DC loads. It has a latching feature that enables the contacts to be held in a fixed position. Its wide range of applications and reliability make it a popular choice for industrial and residential applications.
