Building environments create pressure differentials as temperatures change—sealed enclosures expand and contract, creating vacuum and pressure conditions that draw moisture past simple gasket seals. Multi-barrier protection systems address these challenges through redundant sealing stages that handle different failure modes simultaneously. Primary barriers block direct water entry while secondary seals prevent moisture migration through cable interfaces, where jackets and housings expand at different rates. Advanced sealing systems like Amphe- GTR connectors integrate materials with matched thermal expansion coefficients, Julien Kuoch EMEA Field Application Engineer, Amphenol LTW The shift toward mobile building systems— robotics, AGVs, portable diagnostics—exposes a fundamental limitation of rectangular connectors. Our M5/M8/M12 circular series isn't just about form factor; it's about distributing mechanical stress through threaded coupling while maintaining signal integrity during movement. When a robotic maintenance system needs 17 mixed signals in a single IP67 connection, circular geometry isn't optional—it's physics." eliminating differential movement that creates leak paths while maintaining IP67 protection from −55°C to +125°C—current density and environmental protection that exceeds most industrial power connectors. Circular Locking Connectors for Mobile Building Systems Building automation increasingly incorporates mobile equipment— from robotic maintenance systems to automated guided vehicles—that demands connectivity solutions capable of withstanding continuous movement and vibration while maintaining electrical integrity. Amphenol's M5/M8/M12 circular locking connectors provide industrial- grade connectivity for these dynamic applications through threaded coupling mechanisms that distribute mechanical stress across the entire connector body rather than concentrating loads at individual contact points. 12 Industrial-Grade Building Automation: Rugged, Reliable, Smart
