Safety is our responsibility

To valued SONOFF customers,

It’s been 5 years since SONOFF released the first DIY switch SONOFF BASIC in late 2015. During the past years, we keep upgrading our design to meet the critical regulatory requirements, to offer higher value to the users.

Here are some of the principles we apply in designing the brand new BASICR2:

  1. Mechanical strength is impregnable
    To guarantee the reliability of product quality, 30N pull-push effort is applied to BASICR2, and there is no damage nor movement of the actuating members.
  2. Moisture and dust resistance
    To prevent the device from potential safety hazard caused by occasionally excessive humidity weather. After 48 hours humidity test (Relative humidity: 95%, Temperature: 25°C), the device can work normally.
  3. Environment stress, no problem
    Keep a great durability and reliability in harsh environments. It can continuously work for 4hrs at 60℃ & 24hrs at -10℃ at the 10A of rated load.
  4. Creepage distances, clearances and distances through insulation
    The creepage clearance of all positions is greater than 3mm, while US regulation requires 2mm and EU regulation requires 2.5mm. This can ensure the feasibility of using BASICR2 in various environments, prevent sparking from high humidity environment.
  5. PC940 fireproof and flame-retardant enclosure
    To obtain high heat-resistance and dimensional stability, we adopt LexanTM PC940 resin for the enclosure. This material offers UL-94 V0 flammability rating and good dimensional stability which meets the standard IEC60695-10-2 of ball pressure test at 125℃（257℉）.
  6. Protection against electric shock
    Our product provides adequate protection against accidental contact with live parts in all unfavorable positions of normal use. Ensure the user’s safety in installation and use.
  7. Terminals and terminations
    Terminals for fixed wiring comply with UL 1059, the Standard for Terminal Blocks. Screws and nuts which clamp external conductors. Ensure that the external wire can be clamped during wiring.
  8. Structure stable，no hidden danger in installation
    The structure strictly controls the requirements of insulation, micro disconnection, and installation test to ensure the reliability and safety of the product structure.
  9. No details that affect security will be spared
    Even the product fuse, we also added a heat shrinkable sleeve to ensure better electrical insulation.

Safety is our responsibility, SONOFF will always adhere to these principles to do the user assured products.

Best wishes,

SONOFF Product Team
