Amphenol Corporation is one of the world's largest manufacturers of electrical/electronic connectors, interconnect systems, antennas, and high-speed cable assemblies. Founded in 1932, the company offers an extremely broad portfolio spanning from mil-spec aerospace connectors to consumer USB-C jacks and hyperscale data center backplane systems.

Here's an overview of Amphenol's major connector categories and flagship product lines:

.Major Product Lines

1. Harsh Environment / Military & Aerospace (Amphenol Aerospace)

Amphenol is a leading supplier of MIL-SPEC circular connectors for defense, aviation, and space:

        .MIL-DTL-38999 (Series I/II/III/IV / JT Series) — Subminiature, high-density circular connectors with threaded or bayonet coupling; operating temp −65°C to +200°C, scoop-proof design,           up to 128 contacts. The industry standard for fighter jets, satellites, and naval systems.

        .MIL-DTL-5015 — Older but widely used heavy-duty threaded circular connector for high-power industrial/military apps.

        .MIL-DTL-26482 (Series II) — Bayonet-coupling, medium-size circular connector for general-purpose aerospace.

        .MIL-DTL-83723 / MIL-DTL-22992 (Class L) — Used for high-power and severe-environment applications.

        .2M Micro-Miniature Series — Roughly half the size/weight of D38999, push-pull or threaded, for SWaP-optimized (Size, Weight, Power) soldier-worn and UAV applications.

        .Hermetic & EMI Filter Connectors — Epoxy-sealed or glass-sealed for vacuum/pressure; filtered versions for EMI suppression.

2. RF / Microwave / Coaxial (Amphenol RF / SV Microwave)

        .SMA, SMB, SMC, N-Type, TNC, BNC — Standard RF coaxial connectors for test equipment, wireless, and telecom.

         .HD-BNC / Mini-SMP / SMP-MAX — High-density and board-mount microwave connectors for up to 65+ GHz.

         .Waterproof IP67/IP68 RF connectors — For outdoor/base-station environments.

3. Industrial & Heavy-Duty (Amphenol LTW / Tuchel)

       .M8/M12 (A-coded through X-coded) — Sensor/actuator connectors widely used in factory automation; typically IP67/IP68/IP69K rated.

        .Mini-Fit / AT / D-JAX Series — Rugged rectangular connectors for industrial machinery and transportation.

        .PowerLok G2 / Voltarius — High-current (up to ~450A), high-voltage (up to 1000VDC) interconnects using RADSOK® technology for EVs, hybrids, and battery systems.

4. Board-to-Board & High-Speed Data (Amphenol Communications Solutions / ICC)

       .PwrBlade® / PwrBlade+® / PwrMAX® — Hybrid power + signal backplane/distribution connectors for servers and telecom (up to ~100A/contact).

        .PCIe® Gen 6/7 Card Edge, OSFP, QSFP-DD, CXL (EDSFF) — High-speed I/O for AI/data center (56–128 Gb/s PAM4 signaling).

        .FutureHStak™ / ZettaMAX™ / XtremePass™ — Fine-pitch mezzanine and backplane connectors supporting PCIe Gen 6/7 and 224 Gb/s for HPC/AI clusters.

        .FCI Basics — Bergstik®, Minitek® Pwr, DIN 41612 — Standard board-to-board and wire-to-board headers for commercial electronics.

5. Consumer & I/O Connectors

       .USB Type-C (Standard & Waterproof IPX8), Micro-USB, Audio Jacks — For mobile, wearables, and rugged portable devices.

        .MagConnect® (Onanon) — Magnetic self-mating connectors for medical and industrial use.

.Typical Applications
