Incandescent Aircraft Instrument Bi-Pin Lamp SA4009BPE

Technical Description

Premium aerospace-grade T-1 1/4 (T1.25) sub-miniature incandescent indicator lamps engineered explicitly for flight deck instrumentation backlighting, avionics control arrays, and illuminated dashboard button clusters. Built with a clear glass capsule envelope integrated into a specialized knurled collar assembly featuring twin rigid metal bi-pin terminal plug connectors. Crafted with an impact-resistant tungsten wire filament designed to endure continuous engine vibrations, airframe aerodynamic flex, and structural pressure cycles. Optimized for direct integration into standard low-voltage avionics direct current lines, this highly stable indicators operates at a design configuration of 28.0V while maintaining an ultra-low current draw of 0.04 Amps (40mA) to cast clear, targeted panel illumination over its active service life cycle.
