SES America (SESA) has developed an enhanced version of traditional LED blank out signs with a practical, smarter design for custom solutions.
SESA has overhauled the concept of blank out signs (BOS), providing short and long-term cost-effective solutions for state and municipal agencies. These versatile signs are ideal when displaying three to four messages or symbols as an alternative to expensive, full-matrix DMS messaging.
SESA’s design features robust LED technology, allowing engineers to create a wide variety of symbols and text, and accommodating standard size or custom built housings. Meeting all MUTCD requirements, the housings are built to NEMA 3R standards.
SESA’s multi-phase blank out signs are engineered without a polycarbonate panel, eliminating the ‘phantom effect’, which typically causes motorist confusion. This windowless design maintains a higher contrast ratio for a cleaner, more durable appearance.
Options such as vehicle activation, remote control, and visors assist in enhancing the application awareness. Consistent with all SESA products, these blank out signs were designed to a high energy efficiency standard. Most can be solar powered using SESA technology and implemented in our industry-unique SolarSign product line.
Applications include tunnel lane management, bridge traffic control, weight station, and over-height detection warning systems. SESA’s multi-phase technology displays symbols or text alternatively. For example, a ‘No Left Turn’ symbol and a ‘No Entry’ symbol or text can be displayed on the same mobility blank out sign.
SESA customizes each blank out sign on the needs of the client and project, providing an array of options at a fraction of the cost of full-matrix, dynamic messaging.
