SGJ.3B.330.CLLPV

Engineered for subsea robotics, the SGJ.3B.330.CLLPV by LEMO delivers unprecedented reliability in the Circular Connectors - Adapters category. With 10,000psi pressure rating and hydrogen sulfide resistance, this adapter maintains signal integrity at ocean depths exceeding 6,000 meters.The Standard design incorporates pressure-balanced oil-filled chambers that equalize to ambient depth. This innovative approach eliminates the need for bulky pressure vessels while preventing dielectric fluid contamination.Supporting Female Sockets interfaces, this adapter bridges standard topside equipment to deep-sea rated connectors. The pressure transition zone maintains proper impedance matching throughout the rated depth range.With Male Pins capability, the adapter enables hybrid power-and-data transmission through single penetrators. The design withstands 500V DC potential difference between contacts in seawater environment.The 330 interface utilizes high-strength duplex stainless steel with 90ksi yield strength. All materials pass NACE MR0175/ISO 15156 sour service requirements.Featuring 330 outputs, the adapter incorporates titanium stress cones that distribute cable termination forces. Finite element analysis verifies 3:1 safety factor at maximum rated depth.The 30 configuration was optimized for low-frequency sonar applications. Contact spacing prevents cross-talk between channels at voltages up to 300Vpp.Designed for ROV applications, the 30 output supports simultaneous power, video, and control signals. Each channel is individually tested for insulation resistance >10G in seawater.The Panel Mount option implements compact flange mounting per API 17F standards. The design allows rotation after installation for optimal cable routing.The Bulkhead - Rear Side Nut design incorporates ROV-operable handles for subsea mating. The mechanism provides tactile feedback through manipulator arms.Utilizing Push-Pull technology, the adapter achieves positive locking that increases with depth pressure. The mechanism requires less than 5Nm torque for operation at surface conditions.Selected for its hydrostatic strength, Brass maintains dimensional stability within 0.01% at full depth rating. Material properties were verified through finite element analysis.The Silver housing incorporates subsea identification markers that remain visible in low-light conditions. Fluorescent pigments maintain luminosity after prolonged UV exposure.Including Mounting Hardware, Vacuumtight, this adapter implements sacrificial zinc anodes for cathodic protection. The system maintains proper potential for 10+ years in seawater service.Exceeding IP68 - Dust Tight, Waterproof requirements, the adapter was tested to 1.5 rated depth for 100 cycles. Helium leak testing verifies leakage rates below 1 10^-6 cc/sec.The Shielded design uses corrosion-resistant Monel mesh achieving 70dB attenuation at 100kHz. Shield continuity is maintained through pressure-compensated interfaces.
