Product Overview
Amphenol 000-28000 is a straight, clamp-style MHV (Miniature High Voltage) coaxial plug rated at 5,000V DC/peak. Its military equivalent designation is UG-932/U. The connector uses a solder center contact and outer braid clamp termination, mates exclusively with MHV female jacks conforming to MIL-STD-348, and is built around a PTFE dielectric and nickel-plated brass body. Compatible cables include RG-59, RG-59A, RG-59B, RG-62, RG-62A, RG-62B, RG-71, RG-140, and RG-210. Frequency range extends to 50 MHz.
Key Features
- Voltage rating: 5,000V DC/peak operating
- Connector family: MHV (Miniature High Voltage), bayonet twist-lock coupling
- Military designation: UG-932/U
- Termination: solder center contact, clamp outer braid
- Dielectric: PTFE (Teflon) - white, visible in unit
- Body plating: nickel
- Contact plating: silver
- Compatible cables: RG-59, RG-59A, RG-59B, RG-62, RG-62A, RG-62B, RG-71, RG-140, RG-210
- Frequency range: DC to 50 MHz
- Mates with MHV female jacks per MIL-STD-348 - not compatible with BNC or SHV connectors
Applications
- Building or repairing high-voltage bias supply lines for radiation detectors - strip the RG-59 cable, solder the center pin, assemble the braid clamp, and connect to the detector's HV input jack
- Assembling custom-length patch cables between MHV-equipped laboratory power supplies and vacuum chamber or experimental feedthrough ports in legacy R&D setups
- Maintaining NIM bin modules where MHV jacks are standard on legacy high-voltage outputs and SHV retrofits would require replacing every bulkhead on the chassis
- DIY Geiger counter and scintillation detector builds requiring a safe, quick-disconnect high-voltage connection that won't arc at the bias voltages detectors demand
- Hobbyist and maker high-voltage coaxial projects where a 5,000V-rated bayonet connector is needed and a standard BNC is not rated for the job
Frequently Asked Questions
Will this connector fit my RG-58 cable?
No. The 000-28000 is sized for the larger RG-59 and RG-62 cable groups. RG-58 has a smaller outer diameter and will not clamp correctly. Use an MHV connector sized for RG-58 if that is your cable.
Can this plug mate with a standard BNC jack?
No. MHV and BNC connectors look similar but have different insulator dimensions and pin geometry. Forcing an MHV plug onto a BNC jack is unsafe and physically incorrect. It mates only with MHV female jacks.
Is this the same as an SHV connector?
No. MHV and SHV (Safe High Voltage) are separate, incompatible connector families. They do not mate with each other.
What tools are needed to assemble this connector onto a cable?
A cable stripper or sharp knife for precise jacket and dielectric removal, a soldering iron and solder for the center contact pin, and basic hand tools to torque the clamp nut. No crimp tools required - this is a solder-and-clamp design.
Does this connector include all the parts needed for assembly?
The unit includes the connector body, knurled coupling ring, center pin, rubber gasket, and two washers - everything needed to terminate one cable end.
Geiger counters, scintillation detectors, NIM bin modules - there is a whole world of high-voltage instrumentation that quietly depends on this exact connector doing its job. Yours is waiting to be put back to work.
