3M Releases New Slim Lock Closures to Fit Smaller RF Connections

3M Communication Markets Division announced two new Slim Lock Closures for wireless weatherproofing of smaller RF connections at the cell site. The 3M Slim Lock Mini and the 3M Slim Lock Nano join the 3M Slim Lock Classic, creating a family of varying sizes for wireless weatherproofing needs. The closures offer a re-enterable weatherproofing solution that installs in less than a minute using just one hand, helping to reduce time and simplify install for tower hands. More information on the new Slim Lock Closures can be found on 3M.com/Wireless.

Recently named a finalist for CTIA’s Emerging Technology Award, Slim Lock Closures protect signal integrity by blocking out moisture at both the antenna and Remote Radio Unit (RRU) in tower and roof top installations. The newest releases support the wireless industry’s move toward using Mini-DIN and N-Type connectors on Multiple In and Multiple Out (MIMO) antennas and radios for LTE deployments.

“More and more wireless providers are moving to smaller RF connectors to reduce tower loading with MIMO/ multi-band equipment that enhances service. However, these connectors are crowded together on the antennas/radios, creating a denser area, making it even more difficult to utilize traditional weatherproofing solutions as well as our Slim Lock Classic,” said Sesh Natarajan, marketing manager, 3M Communication Markets Division. “Seeing this challenge, we developed two smaller sizes of our successful Slim Lock Closure, the Mini and the Nano, that could effectively protect connections in this tighter environment while offering the same under-a-minute, easy, one-handed installation process as the original.”

The new Slim Lock Mini will be ready to ship in October 2014. The Slim Lock Nano will be available in winter 2014. The Slim Lock Closure is a CTIA Emerging Technology Award finalist for the category of Wide Area Network – RAN. CTIA will announce the winner during Super Mobility Week on Sept. 10.
