Product Description

XCE Series High-Density Circular Electrical Connector | MIL-C-26482 Series I Equivalent

The XCE Series represents the perfect fusion of proven XC platform reliability with advanced miniaturization engineering. By maintaining the electrical performance and contact arrangement logic of the standard XC Series while significantly reducing contact spacing, we have created a high-density interconnect solution that meets the demanding footprint requirements of modern defense and aerospace systems. Equivalent to MIL-C-26482 Series I, the XCE delivers the ruggedness and field-proven performance of military-grade connectors in a compact, lightweight package. Whether you're upgrading existing systems or designing next-generation equipment with strict space and weight budgets, the XCE Series provides the density you need without compromising on reliability.

Description

The XCE Series High-Density Circular Electrical Connector is a precision-engineered interconnect solution that compresses the proven XC contact arrangement into a smaller footprint—delivering equivalent electrical performance with significant space and weight savings. Building upon the same robust design philosophy as the standard XC Series, the XCE achieves its high-density configuration through optimized contact spacing while maintaining full compliance with MIL-C-26482 Series I requirements. The connector features the same reliable quick bayonet coupling system, providing positive locking and vibration resistance in demanding environments. At the heart of its contact system lies the patented hyperboloid wire spring socket technology, which ensures consistently low contact resistance, smooth mating forces, and exceptional mechanical endurance over thousands of cycles. With five-key polarization options to prevent mismating and flexible gender configurations, the XCE Series offers designers the versatility to optimize panel layouts while maintaining the highest standards of military-grade reliability.

FAQ

Q: How does the XCE Series differ from the standard XC Series?
A: The XCE maintains the same electrical performance and contact arrangement logic as the XC Series but with compressed contact spacing. This results in a smaller overall connector footprint and reduced weight for the same number of circuits—ideal for space-constrained applications.

Q: Is the XCE Series interchangeable with MIL-C-26482 Series I connectors?
A: Yes. The XCE Series is designed with contact density equivalent to MIL-C-26482 Series I, ensuring compatibility with systems designed to this international standard.

Q: What is the advantage of the hyperboloid wire spring socket?
A: Hyperboloid sockets create multiple line contact points, resulting in lower contact resistance, smoother mating forces, reduced insertion/extraction forces, and longer mechanical life compared to standard stamped or machined contacts.

Q: Can I use both pins and sockets in either the plug or receptacle?
A: Yes. The XCE Series offers complete gender flexibility—both plugs and receptacles can be configured with either pin contacts or socket contacts to suit your specific design requirements.

Q: What termination method does the XCE Series use?
A: The XCE Series features solder cup termination, providing reliable, field-serviceable connections ideal for prototyping, maintenance, and applications where crimp tooling is not available.

Q: What patent protects the XCE Series technology?
A: The XCE Series incorporates patented hyperboloid socket technology protected by Chinese Patent No. ZL01270082.7.

Q: Are hermetic versions available?
A: Yes. Hermetic sealing options include bulkhead sealed adapters (50.7kPa, ≤46Pa·cm³/s) and glass sintered hermetic versions (152kPa, ≤0.1Pa·cm³/s) for pressure and vacuum applications.
