Engineered to deliver exceptional performance across demanding aerospace, subsea, and automation systems.
Bulkhead connectors serve as the critical nexus where signal, power, and fluid transitions must cross structural barriers without compromising system pressure profiles or environmental isolation. Unlike standard cable couplers, a bulkhead connector must support sustained mechanical shear forces, high pressure deltas, and corrosive environmental exposure, all while preserving signal attenuation standards.
At Dynalink Electronic Technology Co., Ltd, our OEM bulkhead configurations are built from advanced metallurgical structures (316L Stainless Steel, Titanium Gr. 2, and specialized marine brass) utilizing state-of-the-art Glass-To-Metal Seal (GTMS) and elastomer technologies. This ensures zero leakage under gas pressures reaching up to 10,000 PSI and helium leak tightness exceeding 1x10-9 mbar·l/s.
Maintaining continuous conductive pathways through physical pressure walls requires strict management of the mismatch in thermal expansion (CTE) coefficients between pins, glass/ceramic insulation inserts, and housing walls. We utilize matched compression seals and glass-ceramic matrix technologies to prevent micro-fissures in challenging temperature dynamics spanning from -65°C up to +200°C.
Uncompromising engineered reliability designed for mission-critical operations where equipment failure is not an option.
Providing custom, weight-optimized lightweight bulkhead interfaces capable of sustaining vacuum operations in high-altitude environments, with optimized battery and sensor connectivity.
Designed for low-attenuation optical and high-speed electrical signals, assuring seamless multi-channel data routing across server racks and cooling-fluid boundaries.
High protection rating (IP67/IP68/IP69K) connectors built to withstand toxic washdown fluids, heavy mechanical vibrations, and hazardous explosive atmospheres.
Standardized parameters across our proprietary OEM Bulkhead design portfolios.

Discover how Dynalink optimizes its supply chain to guarantee components are delivered on time, under strict quality control, and at highly competitive price points.
In modern industrial sourcing, supplier resilience is as critical as design capabilities. Operating out of China's core manufacturing ecosystem, Dynalink leverages highly integrated supply chains, providing immediate access to premium metal stocks, precision molding lines, and high-purity glass materials.
By owning our core manufacturing processes—from automated high-density tooling fabrication to testing complexes—we eliminate typical tier-2 subcontractor delays. Our vertically integrated pipeline shortens standard OEM prototype development lead times from typical 12-week cycles down to only 4 weeks.
Furthermore, our materials research divisions work on overcoming technological bottlenecks in solid-state systems, maximizing capacitor energy densities, and producing low-loss connectors that support complex aerospace, marine, and high-frequency configurations.
Fully compliant with global environmental, safety, and performance standards.
A strategic vision detailing our engineering progress and the future of connectivity design.
Optimizing micro-miniature configurations (e.g., 0.50mm and 0.80mm pitch ranges) designed to support multi-pin density configurations within small space parameters.
Combining optical fiber pathways and high-current electrical lines within a single hermetically sealed bulkhead interface, perfect for subsea and deep-space arrays.
Embedding micro-sensors directly within connector housings to continuously measure temperature, humidity, and insulation resistance in real-time, providing preventative maintenance alerts.
Explore our second category tier featuring hybrid fluid, power, and low-voltage high-capacity electronics.
Addressing technical queries from procurement professionals and design engineers.
Glass-to-Metal seals provide a true hermetic barrier, sustaining pressure differences over 10,000 PSI and working reliably across long lifespans. Unlike elastomers, glass seals are inert and do not suffer from outgassing under high-vacuum settings, polymer degradation from UV exposure, or chemical breakdown in corrosive environments. This makes GTMS ideal for petrochemical systems, deep sea submersibles, and aerospace hulls.
Our bulkhead connectors incorporate built-in EMI filter pins, internal ground washers, and continuous conductive shielding paths. When mounted onto metal enclosures, our grounding flanges minimize contact resistance, providing attenuation rates above 65 dB up to 10 GHz. Additionally, we utilize gold-plated contacts to ensure low electrical resistance and protect against corrosion over years of service.
Yes, we specialize in high-reliability hybrid assemblies. We design custom bulkhead connectors that routing fluid lines (such as liquid cooling loops or pneumatic controls) alongside electrical pins in a single connector housing. This integration is highly valuable for aerospace cooling systems, automated tooling plates, and deep-sea ROVs.
All Dynalink production runs are covered under our ISO 9001:2015, ISO 14001:2015, and ISO 45001:2018 management system audits. Upon request, we provide material trace documents (MTRs), helium leak test logs, dielectric testing certificates, IP-rating compliance certificates, and RoHS / REACH chemical declarations.
