DBR71210F

Reed relays are one of the widely used electronic switches that are designed to be used for higher range of applications compared to other types of relays. DBR7121F is one such reed relay that uses a flexible metal reed contactor as an input component and is designed to be used in printed circuit board (PCB) applications. It is specifically designed for switching/controlling of low power signals with maximum current and voltage ratings.

The DBR7121F reed relay has a single-pole double-throw (SPDT) contact configuration that allows it to be widely used for applications such as switching of circuit inputs, relay signal paths, logic circuits, switch matrices, and other interfaces. It has a coil resistance range of 100-300Ω and coil operating current of 25mA. The contact material used in the reed relays is usually made of precious metals like silver, gold, copper and phosphor bronze. This combination of contact materials provides it with the highest level of accuracy, reliability and performance.

The DBR7121F reed relays work on a basic operation principle. When the coil voltage is applied, the contact points inside the reed relay are actuated. The arrangement of the contact points and coils is such that the contacts move and then close when the applied voltage meets a given threshold. Once the contacts close, the circuit is switched on and the current is allowed to flow through it. When the voltage is disconnected, the contact points move in the opposite direction and then the contacts open, thus breaking the circuit and prevent any further current from flowing.

Due to its fast switching action and low power consumption, these reed relays are suitable for use in various applications like switching of data lines, logic devices, signal lines and Ethernet circuits. The use of these relays in broadcast circuits for switching and controlling of audio and video signals as well as in security systems for detecting movement and intrusion is quite common. The reed relay is also used in other fields such as consumer electronics, medical electronics, industrial instrumentation, telecommunication, and instrumentation.

The DBR7121F reed relay merges great features such as low coil power consumption, high creepage distance, durable construction and excellent thermal stability; all of which result in high-reliability and superior performance of the system. It is a dependable solution for controlling and switching signals up to 250mV and is capable of switching current of over 200mA.

These reed relays are widely used across a variety of industries for creating high-reliability electrical connections with minimal external power and space requirements. The DBR7121F reed relay is specifically designed to work in continuously changing conditions, making it ideal for use in extreme temperature or shock applications. The reed relay also provides higher immunity against contact corrosion, thus making it reliable for use even after long-term operation.
