Hermetically sealed thermostatic time-delay relay tube conforming to MIL-R-19648 and military slash-sheet standards, 26-volt AC/DC internal heater operating voltage rating featuring an integrated automatic line-voltage thermal regulation profile, delivers a precise 20-second non-adjustable initial time-delay duration before actuation, features a single-pole single-throw normally closed (SPST-NC / "N" variant) contact layout configuration rated for 3 amperes at 115 volts AC, equipped with an industrial 9-pin miniature button glass base or wire-hook header terminal array layout, designed to handle sequential power staging and cathode preheating cycles across legacy radar grids and defense communication systems. Unit Sourcing Compatibility: This component came out of military transmitter decks, aviation signal conditioning chassis, and vintage avionics subsystems managed under CAGE Code 70563. Exact Industry Equals: Amperite 26N020T and Amperite Co. 26N020T. [1]
