Protect critical perimeters and secure sensitive doors with the Edwards Signaling 2757-L magnetic contact, engineered for tamper‑resistant surveillance and monitoring where reliability matters most. This high-security magnetic contact uses triple-biased reed switches and total encapsulation to resist defeat by external magnets and prevent access to the switch or wiring. The anodized aluminum surface-mount housing and concealed recess mounting provide a low-profile, durable solution for prisons, military, government, and demanding commercial environments. With SPDT output rated for 50V and 0.5A (25 VA) and a 0.375-inch operating gap, the 2757-L integrates seamlessly with access control, alarm panels, and security monitoring systems. The unit includes a 3' vinyl-jacketed cable for straightforward installation and is factory‑calibrated for steel doors to avoid sticking on infrequently used openings. Installers appreciate the robust construction and industry-standard compatibility that speed deployment without sacrificing security. Choose the Edwards Signaling 2757-L for dependable perimeter protection, intrusion detection, and surveillance integration — contact our sales team to specify or order for your next high-security project.
