Product Overview
Dage UG-932/U MHV (Miniature High Voltage) straight male plug for RG-59, RG-59/U, RG-62, RG-62A/U, and RG-71 coaxial cable. Clamp-style termination: threaded compression nut and rubber grommet grip the cable jacket and shield mechanically; the center conductor is soldered to the silver-plated contact pin. Rated 5,000 VDC. Body is brass with nickel plating; insulator is PTFE. Mates with standard MHV female jacks and bulkhead receptacles including the UG-931/U.

Applications
- Fabricating or repairing high-voltage interface cables for legacy lab power supplies - strip RG-59 or RG-62 to dimension, solder the center pin, thread on the compression hardware, and plug directly into the front-panel MHV jack on vintage HP/Harrison or Bertan high-voltage supplies
- Terminating HV bias cables for NIM bin instrumentation - assembling the plug onto a custom-length coaxial run that delivers bias voltage to detectors or preamplifiers housed in a nuclear instrumentation module chassis
- Building or restoring radiation detection setups - connecting a photomultiplier tube (PMT) or Geiger-Müller tube bias supply to a detector head without modifying the original MHV chassis connectors on rare equipment
- High-voltage wiring for amateur fusor builds and vacuum tube projects where 5kV-rated, BNC-keyed connectors are required and SHV hardware is not already in place
- Custom-length HV patch cables for bench work - makers and hobbyists needing a safe, solderable high-voltage coaxial termination without proprietary crimp tooling
Frequently Asked Questions
Will this mate with a standard BNC jack on my instrument?
No. MHV connectors use a bayonet coupling that looks similar to BNC but the elongated insulator and contact geometry are intentionally incompatible with standard BNC jacks. This is a safety feature - cross-mating a 5,000V connector with BNC hardware not rated for that voltage is dangerous. This plug mates only with MHV female receptacles such as the UG-931/U.
Will this mate with an SHV (Safe High Voltage) jack?
No. SHV connectors use a protruding insulator design that is physically incompatible with MHV plugs. The two standards do not interchange.
Are all the clamp assembly parts included?
Yes. The photo confirms the full complement: main body with knurled coupling ring and PTFE dielectric insert, threaded compression bushing, silver center pin, metal washer, and rubber grommet. No additional hardware is needed to assemble and install the connector - solder and a soldering iron are required for the center pin.
Do I need a special crimping tool to install this?
No. This is the clamp-style UG-932/U, not a crimp variant. Termination uses the included threaded compression nut and grommet to grip the cable mechanically. The only tool required beyond standard hand tools is a soldering iron for the center conductor pin.
What cable types fit this connector?
RG-59, RG-59/U, RG-62, RG-62A/U, and RG-71. Larger cables such as RG-8 or RG-213 will not fit the clamp bushing entry diameter.
Nickel-plated brass, PTFE dielectric, silver contact - the kind of hardware that outlasts the equipment it was built for. Your high-voltage setup deserves a connector that takes the voltage as seriously as you do.
