When sourcing OEM remote controls, you must prioritize transmission technology (IR, RF 2.4GHz, or Bluetooth). For IR remotes, verify the operating distance (typically 8-10 meters) and beam angle (30-60 degrees). For Bluetooth or RF models, ensure stable pairing protocols and low power consumption chipsets. Additionally, specify the button lifecycle (usually >100,000 presses) and material requirements such as ABS plastic for the shell and silicone for the conductive pads to ensure tactile feedback and durability.
