Type AT Signal

The Type AT Signal is a compact, space-saving unit designed specifically for rapid transit systems where clearance is limited. Ideal for tunnel and underground installations, it features a single optical lens, making it highly effective in low-light environments where the efficiency of a doublet lens isn't necessary.

Key Features

• Compact form factor for tight clearances
• Configuration for multiple aspects
• Durable, proven construction

Customer Benefits

• Reliable performance in high-frequency service
• Easy to install in constrained environments
• Felxible for diverse transit applications

Compact Design for Tight Clearances

The signal comes with a 5-inch (12.7 cm) lens and a 3.5-inch (8.9 cm) focal length. Lens colors can be specified in red, yellow, green, lunar white, or clear, depending on your application needs.

Thanks to its modular design, multiple Type AT units can be bolted together vertically to create custom signal configurations. These units are typically supplied with mounting brackets for installation on subway walls or ceilings.

When space is tight and performance can't be compromised, the Type AT Color-Light Signal is the perfect solution.
