081-0408-01-343 is a neon panel mount indicator designed for 11/16" mounting hole applications with watertight construction. It operates at 105–125 AC-DC voltage and uses a T 3 1/4 miniature bayonet base neon lamp (521-9053, B1A type). The base features chrome plated brass construction with a chrome plated bezel, while the cap is made of polycarbonate and available in multiple colors (red, amber, white, clear). The mounting interface includes an 11/16 x 27 MS thread with 1.98 [0.08] x 3.18 [0.13] mm slot dimensions and a maximum height of 46.04 mm (1.81 inches). This indicator is commonly used in industrial control panels, machinery status displays, and equipment monitoring applications where reliable visual feedback and environmental protection are required.
