What Connectors Do RC Receivers Use?
What connectors do RC receivers use?
Introduction:
Remote Control (RC) receivers are essential components in RC systems that receive signals from transmitters and convert them into controls for model vehicles, aircraft, and other RC devices. These receivers come in various types and sizes, but they all rely on connectors to establish a secure and reliable connection with other components of the RC system. In this article, we will delve into the world of RC receivers and explore the different types of connectors commonly used in these devices.
Types of RC Receivers:
There are primarily two types of RC receivers: Non-computerized or Analog RC receivers and Computerized or Digital RC receivers. While the basic principle of both types remains the same, they differ in terms of complexity, features, and connectors used.
*Non-computerized or Analog RC Receivers:*
Analog receivers are the simpler of the two types, often used in entry-level RC systems. These receivers typically operate on a single channel, meaning they can receive signals for only one control function at a time. The connectors used in analog receivers are generally standardized and specific to the particular RC system they are designed for.
Common connectors used in analog RC receivers include:
1. Servo Connectors: Servo connectors are widely used in RC systems to connect RC receivers to servos, which are responsible for controlling various mechanical movements in the model vehicle or aircraft. The most common type of servo connector is the Futaba J-style connector, which features three pins and a plastic housing for secure connections.
2. Battery Connectors: Analog RC receivers require power to function, and batteries are a common source of power. Therefore, battery connectors are essential to establish a connection between the receiver and the power source. The two most common types of battery connectors used in analog RC receivers are the Tamiya-style connector and the Deans connector.
3. Antenna Connector: Analog RC receivers also require antennas to receive the transmitter''s signals. These receivers often use coaxial connectors, such as the SMA (SubMiniature version A) connector, to attach the antenna securely.
*Computerized or Digital RC Receivers:*
Digital RC receivers, also known as computerized receivers, are more advanced and feature-rich compared to analog receivers. They are commonly used in high-end RC systems and provide multiple channels for simultaneous control functions. These receivers utilize connectors capable of transmitting digital signals and supporting additional features.
Common connectors used in digital RC receivers include:
1. PWM Connectors: Pulse Width Modulation (PWM) connectors are widely used in digital RC receivers to transmit control signals from the receiver to servos or electronic speed controllers (ESCs). These connectors feature three pins and are specific to the receiver and servo manufacturer.
2. S.Bus Connectors: S.Bus is a digital serial communication protocol commonly used in high-end RC systems. S.Bus connectors allow multiple servos to be connected to a single wire, reducing the number of required connectors and simplifying wiring. The most popular S.Bus connector is the Futaba S.BUS 2.
3. Telemetry Connectors: Digital RC receivers often support telemetry, which enables the transmission of real-time data, such as battery voltage, signal strength, and temperature back to the transmitter. Telemetry connectors can be proprietary to the RC system manufacturer or standardized connectors like JST connectors.
Conclusion:
In the world of RC receivers, connectors play a crucial role in establishing reliable connections between receivers, servos, batteries, antennas, and other components of the RC system. The choice of connectors depends on the type of RC receiver being used, whether analog or digital. Analog receivers commonly use servo connectors, battery connectors, and antenna connectors. On the other hand, digital receivers utilize PWM connectors, S.Bus connectors, and telemetry connectors. Understanding these connectors is essential for RC enthusiasts and hobbyists to build, modify, and optimize their RC systems for the best performance and experience.
