Product Overview
Engineered for high-voltage coaxial lines, the AMP 51426-2 straight SHV plug provides secure bayonet coupling for test equipment, nuclear instrumentation, and laboratory power circuits. Rated for 5,000 volts peak (3,500 volts RMS), the connector interfaces with RG-59 and RG-62 series coaxial lines using a dual-crimp termination for the center contact and outer braid. The SHV design utilizes recessed contacts and overlapping insulation barriers to prevent accidental electrical shock during disconnect.

Frequently Asked Questions
What coaxial cable sizes fit the AMP 51426-2 connector?
It is designed for RG-59, RG-59A, RG-59B, RG-62, RG-62A, RG-62B, and RG-140 coaxial cables.
Can an SHV plug mate with a standard BNC jack?
No. SHV connectors use thicker dielectric insulators and a specific outer pin configuration to prevent accidental mating with low-voltage BNC jacks.
What contact type is included with this plug?
This plug kit includes a gold-plated female socket center contact for dual-crimp installation.
What tooling is needed to assemble this connector onto coaxial cable?
Assembly requires standard coaxial cable stripping tools and a dual-crimp hand tool matched to RG-59 or RG-62 ferrule and center contact hex crimp dimensions.
There is no substitute for the right high-voltage connector when thousands of volts are running down your coax. Crimp your lead, lock the bayonet, and keep the charge exactly where your circuit needs it.
