"Float Mount" technology for consistent microwave performance. |
| Concentric Twinax Contacts | Designed for protection from magnetic and electrostatic interference, including nuclear electromagnetic pulse. Maintain shield integrity. | Sizes 8 & 12 | 77-100 Ohm | 030 MHz (Size 12), 020 MHz (Size 8) | N/A | Scoop-proof pins, crimp terminable to twisted shielded cable, suitable for MIL-STD-1553B applications. |
| Triax Contacts | Provide additional shielding when terminated to triax cable. Features three conductors separated by dielectric insulation for isolated ground planes and improved shielding. | Sizes 8, 10 & 12 | 50/75 Ohm | Size 12: 0-30 MHz, Size 10: 0-300 MHz, Size 8: 0-500 MHz | N/A | Crimp termination, can be mixed with coax, twinax, and power contacts. |
| Quadrax Contacts | Four strategically spaced inner contacts form two 100 or 150 Ohm matched impedance differential pairs. Ideal for high data transfer rates and low power consumption. | Size 8 | 100/150 Ohm | Up to 1.25 GHz (standard), up to 6.5 Gbps per pair (Split-Pair) | Exceeding 2.5 Gbps (standard), up to 6.5 Gbps per pair (Split-Pair) | Controlled impedance, excellent EMI compatibility, available in crimp or PC tail termination. Requires modified MIL-DTL-38999 connector. |
| Differential Twinax Contacts | Two strategically spaced inner contacts form one 100 or 150 Ohm matched impedance differential pair. Designed for high data transfer rates and low power consumption. | Size 8 | 100/150 Ohm | Up to 1.25 GHz | Exceeding 2.5 Gbps | Controlled impedance, excellent EMI compatibility, available in crimp or PC tail termination. Requires modified MIL-DTL-38999 connector. |
| PC Tail Contacts (Coax, Twinax, Triax, Quadrax) | Designed for direct connection to printed circuit boards, offering a cost-effective packaging solution for limited space applications. | Coax: 8, 12, 16; Twinax: 8, 10, 12; Triax: 8 (socket only); Quadrax: 8 | N/A | Up to 500 MHz (Coax/Triax), 0-20 MHz (Twinax) | N/A | Factory pre-assembled, standardized termination to PCB. |
| Transition Adapters (Quadrax, Differential Twinax) | Facilitate launching of controlled impedance signals to printed circuit boards. Available in threaded or cable-to-board styles, 90 or straight receptacles. | N/A | 100/150 Ohm | N/A | N/A | Matched impedance, push-pull quick disconnect options available for Micro D-Twinax adapters. |
| Matched Impedance Coaxial Contacts | Specifically designed for RF/microwave, high-frequency, and high-performance requirements. Feature a captivated inner contact for durability in bent cable applications. | Size 12, 8 | 50/75 Ohm | 03 GHz (up to 40 GHz for specific variants) | N/A | Low VSWR, low insertion loss, ideal for MIL-STD-1760 applications. |
