Sonoff Din Rail Wire Connectors D211 - DIN Rail Lever Terminal Block, Quick Connect

TheSonoff D211 is a professional electrical connector terminal block designed specifically for DIN rail mounting. It combines the simplicity of lever connectors with the stability of industrial mounting, making it the ideal solution for organising wiring in switchboards where smart modules (such as Sonoff POW, Dual or DIN Rail range) are installed. With D211, your connections become safer, cleaner and extremely manageable.

Key Selling Points

• Standard DIN Rail Mountable: Snaps securely onto 35mm DIN rails, allowing perfect alignment and aesthetic organisation of wires within the electrical panel.

• Lever Technology: Eliminates the need for screwdrivers to secure wires. Lift the lever, insert the cable and lock. The connection is instant, firm and resistant to loosening caused by vibration or temperature variations.

• Universal Connection: Accepts both rigid (monofilament) and flexible (multifilament) cables. It's the perfect solution to transition from solid home wiring to flexible smart device wiring.

• High Quality Materials: The housing is made of flame retardant nylon (PA66), providing excellent electrical insulation and high temperature resistance, ensuring a long installation life.

• Easy Maintenance: Allows quick disconnection of a circuit for testing or modifications without disturbing the rest of the connections in the panel, a major advantage over conventional terminal strips.

• Space Saving: The vertical and compact design allows a large number of connectors to be installed in a small space, keeping the electrical panel ventilated for optimal cooling of Sonoff modules.

Examples of Use

1. Smart Switchboard Organisation: Use D211 connectors to group Null (Neutral) or Ground near DIN-rail mounted Sonoff relays, avoiding "spidering" of wires.

2. Power Distribution Point: Ideal for branching the main power supply to multiple power monitoring modules (e.g. Sonoff POW Elite), ensuring reliable, high amperage electrical contacts.

3. Industrial Automation/DIY Projects: Perfect for control panels where quick access to terminals is essential for recalibration or system expansion.
