Feature:1. DC6V36V Receiver: Receiver input DC6VDC36V, miniature, the learning point is matched with the transmitter on the receiver, the low voltage relay is inward, the superheterodyne receiver module has high receiving sensitivity and good anti interference performance.2. DC5V24V Transmitter: It is a radio frequency transmitter board without shell and buttons, just input DC5VDC24V power supply to it, it can transmit signals, it is a miniature transmitter module for learning code receiver.3. Stable Signal: The transmitter module can be controlled by smoke detectors or other sensors or microcontrollers. The radio frequency remote control adopts radio frequency technology, and the signal is stable.4. Large Range: The signal of the mini RF switch can pass through wall, floors and doors, stably controlling the receiver from anywhere within a reliable distance, with a maximum range of up to 100 meters without obstacles.5. Application: RF remote control switch is mainly used in switches, lamps, relays, remote controls, circuit boards, speakers, power switches, home wireless control and security industries, and battery on/off for small devices.Specification:Item Type: RF Remote Control SwitchMaterial: PCBReceiver:Working Voltage: DC6V-36VMaximum Load: 5A (If You Control the Motor, the Load is Less Than 3A)Working Frequency: 433MHzFrequency Deviation: Greater or Less Than 0.2MHzOperating Temperature: -20 Degrees Celsius - +80 Degrees CelsiusReceive Sensitivity: -109dBmModulation: Amplitude Modulation (AM)Encoding Type: Learning Point Add EmitterOutput Status: Momentary.
