4987-2

Pomona Electronics's 4987-2 represents the gold standard in Banana and Tip Connectors - Jacks, Plugs solutions, specifically developed for mission-critical power distribution networks. Its patented contact design ensures <1 V noise generation in sensitive measurement circuits.As a Banana Jack connector, it incorporates redundant contact points that achieve 99.99% connectivity reliability per Telcordia GR-1217-CORE. The bifurcated spring design maintains constant normal force throughout the product lifecycle.The Female configuration features gold-over-nickel plating (50) that provides superior corrosion resistance in salt spray tests exceeding 500 hours. Mating surfaces are precision-lapped to sub-micron flatness standards.With Standard Banana dimensions, the connector achieves VSWR <1.2:1 up to 18GHz. The controlled impedance profile matches MIL-PRF-55339 requirements for microwave applications.Optimized for Free Hanging (In-Line) installations, the flange design incorporates anti-rotation tabs that prevent orientation errors during assembly. The mounting hardware is rated for 200N tensile load in aerospace wire harnesses.The Crimp or Solder method utilizes diffusion-bonded interfaces that eliminate intermetallic growth. Independent testing shows <0.5dB insertion loss variation after 10,000 thermal shock cycles.Sheathed properties exceed UL94 V-0 flammability ratings while maintaining flexibility at -40 C. The material formulation is REACH-compliant and halogen-free for environmental safety.Red options include laser-markable surfaces for permanent identification. The high-contrast pigments meet ANSI Z535.1 safety color requirements for industrial control panels.Designed for 14-16 AWG cabling, the strain relief system prevents conductor fatigue at bend radii down to 4x diameter. The captive screw design prevents loose hardware in vibration environments.
