4510AU
Overview
Protect overhead doors and floor-level access points from heavy vehicular traffic with the George Risk Industries GRI 4510AU concrete concealed magnetic contact. Engineered specifically for recessed mounting in concrete, this SPDT reed-form magnetic contact stays flush with the floor so forklifts, trucks and other industrial equipment can pass over it without damaging the sensor. The 4510AU’s stainless-steel housing and heavy-equipment protection make it ideal for harsh warehouse and loading-dock environments where corrosion and impact resistance matter.
With a wide 3.5-inch standard gap and a conservative 5W/0.250A switching rating, the 4510AU reliably reports open/closed status to security panels, access control systems and monitoring platforms even on loose or worn doors. Its wired connectivity and recessed mount simplify installation into concrete floors for a discreet, tamper-resistant alarm contact. Backed by George Risk Industries’ lifetime limited warranty, the 4510AU delivers durable performance for surveillance, security and industrial access control. Add the GRI 4510AU to your next warehouse or dock application for dependable perimeter monitoring—contact us for pricing or to place an order.
