Slim Design and Tool-Free Terminations. A truly standard-setting solution for all conductor types from 0.2 to 4 mm². The new 221 Series Inline Splicing Connector with lever combines all the trusted advantages of the 221 Series Splicing Connectors into a slim design. Offering unsurpassed simplicity, speed and reliability, the 221 Series provides universal conductor connections – with lever technology that eliminates tools – while offering a visibly secure conductor contact. Where multiple poles are required, optional adapters provide completely modular mounting. Users get the flexibility of having five fixed-position poles in one adapter – whether it’s with or without strain relief, on DIN-rails with a snap-in mounting foot, for screw mounting, adhesive mounting, tie-on mounting or suspended mounting. As a universal connection technology, the 221 Series Inline Splicing Connector’s compact dimensions not only improve your current installations, the small footprint also opens up a wide variety of new applications. These include space-restricted applications like laboratory and test setups, production test bays, lighting connection in suspended ceilings, or extending loudspeaker cables and distribution boxes in industrial applications.
