640921-1

TE Connectivity AMP Connectors's 640921-1 sets new standards in Terminals - Quick Connects, Quick Disconnect Connectors technology, optimized for next-generation industrial automation systems. These quick-disconnect terminals feature innovative contact geometries that reduce insertion force while maintaining high retention strength. The precision-engineered components deliver exceptional performance in extended temperature ranges.The Standard design options address diverse interconnection challenges. Stacked configurations enable vertical space utilization in control cabinet wiring.With Female variants available, system designers can implement balanced signal paths. The female contacts feature dual-beam designs for redundant contact points.Precision-machined to 0.110" (2.79mm) specifications, the tabs maintain consistent wipe characteristics. This dimensional stability is crucial for high-cycle applications.The 0.016" (0.41mm) material gauge provides optimal current density characteristics. The tapered contact edges facilitate blind mating in confined spaces.The 0.250" (6.35mm) engagement dimension ensures proper contact alignment. This critical parameter maintains stable connection resistance over thousands of mating cycles.At 0.800" (20.32mm), these terminals achieve ideal leverage ratios for manual insertion/extraction. The ergonomic design reduces installer fatigue during mass termination.Crimp methods cater to different production environments. The solder versions feature thermal mass optimization for wave soldering processes.Supporting 18-22 AWG conductors, these terminals handle both signal and power applications. The graduated wire stops prevent over-insertion during assembly.The Non-Mating End Insulated options provide application-specific dielectric protection. Fully insulated versions meet reinforced insulation requirements for safety-critical systems.Free Hanging (In-Line) variants address various installation scenarios. Chassis-mounted types offer secure grounding paths for EMI-sensitive equipment.The Red identification system simplifies circuit tracing. UV-stable pigments ensure long-term color retention in outdoor installations.Utilizing Brass, the contacts achieve optimal spring properties. The beryllium copper alloys offer excellent stress relaxation resistance.Tin platings provide tailored surface properties. The silver finishes deliver superior conductivity for high-frequency applications.
