4897-2

The 4897-2 from Pomona Electronics revolutionizes Banana and Tip Connectors - Jacks, Plugs technology with its aerospace-grade construction. Developed for satellite payload systems, it maintains stable RF performance across -55 C to +175 C operational extremes.This Banana Plug, Stackable connector implements quad-redundant contact springs that guarantee continuous connectivity under 15G vibration. The hermetically sealed version maintains <5 10^-8 atm cc/s helium leak rate.Male variants feature rhodium-plated contacts that exhibit <5m contact resistance variation after 500 thermal cycles. The non-magnetic construction prevents interference with sensitive instrumentation.Machined to Standard Banana specifications with sub-micron surface finish, the interface achieves VSWR <1.1:1 up to 40GHz. The diamond-like carbon coating reduces wear to <0.1 m per 10,000 cycles.The Free Hanging (In-Line) configuration includes integral anti-vibration lockwire provisions per NASA-STD-8739.4. The titanium hardware withstands 2000-hour salt fog exposure per ASTM B117.Utilizing Solderless technology, the connection system passes MIL-STD-1344 Method 3009.1 shock testing. The diffusion-bonded interface maintains <0.1dB insertion loss variation in orbital thermal cycling.Non-Mating End Insulated materials are space-qualified with total mass loss <1.0% and collected volatile condensable materials <0.1% per ESA ECSS-Q-ST-70-02C. The radiation-resistant formulation withstands 100Mrad TID.The Set Screw, Safety Collar implementation includes built-in Faraday cage shielding that provides >100dB EMI attenuation. The hermetic glass-to-metal seals maintain vacuum integrity in space applications.Red markings are laser-etched for permanent identification in vacuum environments. The high-emissivity coatings maintain thermal balance in spacecraft thermal control systems.Designed for 18-22 AWG wiring, the strain relief system prevents microphonic noise in sensitive sensor circuits. The clamping force is calibrated to 2% accuracy for consistent performance.
