  • Model: 0020329 (S1SM-DC12 & C-1)

Please Choose:


This 1CH mini garage door remote control operates in the 315/433MHz frequency, with voltage AC 110~240V or DC 0~28V. It works with momentary mode, which means press and hold the remote button, turn on/open the electrical device; release the button, turn off/close the device. Applications include gate remote control, motor remote control, garage door remote control, light remote control, etc.



  • Wireless control, easy to install.
  • Control Lights, Motors, Fans, electrically operated Doors/ Locks/ Windows/ Blinds/ Cars or Other Appliances with voltage AC 110~240V or DC 0~28V. 
  • You can turn on/off the receiver with transmitter (remote control) from any place within a reliable distance; the wireless signal can pass through walls, floors and doors.
  • Reliable control: The transmitter (Encoding) and the receiver (Decoding) use an 8-bit code.
  • One/several transmitters can control one/several receivers simultaneously.
  • If you use two or more receivers in the same place, you can set them with different codes.
  • Transmitting Frequency: 315MHz / 433MHz

  • The theoretical distance is 100m, which shall be operated in an open ground; no barriers and no any interference. But in actual operation, it is hindered by trees, walls or other obstacles, or interfered by other signals. Therefore, the actual distance can not reach 100m. If you need longer range, please choose other series of remote control, such as CB Serie (1000m/3000ft) - Click here; Or you can add the External Extend Antenna (model:0020909 ) on the receiver for improve the range - Click here.
