The ännt AE275/M50 is a high-performance automatic bollard engineered for critical-infrastructure protection, secure facilities, logistics centers, and government sites. Certified to ASTM M50/K12, the AE275/M50 is designed to stop a 15,000-lb vehicle traveling at 50 mph, delivering top-tier security against high-speed intrusion attempts.
This model uses a reinforced steel cylinder, a heavy-duty operating frame, and a high-reliability hydraulic system capable of 2,000 cycles per day. With an average service life exceeding three million cycles, the AE275/M50 is built for demanding environments where reliability is non-negotiable.
The bollard integrates with standard ännt access-control systems and supports safety devices such as induction loops, traffic lights, alarms, and remote triggers. An optional EFO (Emergency Fast Operation) upgrade can raise the bollard in a rapid-response mode for heightened security conditions. It is engineered for consistent performance in extreme temperatures and includes drainage requirements to protect the internal mechanism.
The AE275/M50 delivers deep-foundation stopping power, long-term durability, and smooth daily operation, making it a dependable solution for any site requiring maximum vehicle-threat mitigation with automated access control.
