3750-4

The 3750-4 by Pomona Electronics pioneers new Banana and Tip Connectors - Binding Posts technology for extreme environment applications. Designed for deep-sea and space exploration equipment, 3750-4 maintains reliable performance under 10,000psi pressures and in vacuum conditions, making it the connector of choice for submersibles and satellite systems where failure is not an option.Available in Standard configurations, this product line meets extreme environment demands. The pressure-balanced version demonstrates perfect functionality at full ocean depth pressures.Engineered with Knurled head geometry, these connectors enable operation with thick gloves. Testing shows 100% successful mating attempts in -50 C conditions with simulated Mars mission gloves.Featuring Threaded and Turret technology, these binding posts achieve hermetic sealing. Helium leak testing confirms <1 10^-8 cc/sec leakage rates at all rated pressures.Standardized on 8-32 threads, these components meet ASME PVHO-1 standards. Finite element analysis shows uniform stress distribution at 20,000psi external pressure.Rated for 15 A, these connectors handle power transmission in extreme conditions. Testing confirms stable performance from -200 C to +300 C operational range.Fabricated from Brass, the connector body withstands deep-sea corrosion. Testing shows no measurable material loss after 5 years in simulated seawater at 5 C.The Gold plating was developed for space applications. Outgassing testing meets NASA ASTM E595 with total mass loss <0.1% and collected volatile condensable materials <0.01%.Available in Yellow, these connectors maintain visibility in all environments. The high-contrast pigmentation remains distinguishable in both full sunlight and complete darkness.
