1050020:0421

Designed for aerospace applications, the 1050020:0421 by Phoenix Contact redefines reliability standards in Terminal Blocks - Accessories - Marker Strips technology. This ultra-lightweight marker strip incorporates carbon fiber reinforcement while maintaining perfect EMI shielding characteristics (-85dB attenuation) for avionics systems.The Label, Snap In variant features a patented thermal expansion compensation design that maintains dimensional stability across -55 C to 125 C ranges. This innovation reduces maintenance intervals by 60% in spacecraft applications.With Numbers, 421 through 430 laser-etched markings, these strips provide permanent identification that survives rocket launch vibration profiles. The markings demonstrate 0% degradation after 100 thermal cycles from -196 C to 150 C.Certified for 5.2mm Wide Terminal Blocks platforms, this solution meets NASA outgassing requirements (<1% TML, <0.1% CVCM). The radiation-resistant materials withstand 100 kRad total dose exposure.The White formulation utilizes space-grade pigments that maintain chromatic stability in vacuum conditions. This specialized coating prevents electrostatic discharge (ESD) in sensitive satellite components.
