An R85049/87-22Z03 is a double-pole, double-throw (DPDT) radio-controlled model relays used in a variety of radio-controlled devices. It has very reliable performance when operating in radio control applications and is characterized by low voltage drop and low current consumption.

The R85049/87-22Z03 is a simple example of a double-pole, double throw (DPDT) circuit. It is normally an open circuit, but when a specific power level is applied to its control circuit, the relay switches. The control circuit is the only active part of the circuit - the two common contacts are wired together and the two normally open contacts are each wired to an external load. When the control is applied, the two common terminals are connected to opposite sides of the load.

The R85049/87-22Z03 is mainly used in radio-controlled devices, such as cars, helicopters, and boats. In these applications, it is used to control the motors, servos, and other onboard electrical circuits. The device is also used in electronic thermostats, timers, and switches. In most cases, the R85049/87-22Z03 is used to activate and deactivate electronic circuits on command.

The working principle of the R85049/87-22Z03 is based on a magnetic field and electromechanical relays. The magnetic field is generated by applying a voltage to the relay\'s coil. This creates a magnetic field that attracts the relay\'s armature. When the armature is attracted, the DPDT contacts are switched. As the voltage is applied, the contacts close, and when the voltage is removed, the contacts open.

The R85049/87-22Z03 is widely used in radio-controlled models and other applications. Its low voltage drop and low current consumption make it a reliable and cost-effective choice for these applications. Although the R85049/87-22Z03 is a simple circuit, its versatile design can be used for a wide range of applications.
