Product Overview
Amphenol 000-28100 is an MHV (Miniature High Voltage) right-angle clamp plug rated at 5,000 V peak and 5 A maximum. Male pin contact, 90-degree body, solder center conductor, mechanical braid clamp attachment. Brass body with nickel plating, brass contact with silver plating, PTFE insulator. Designed for RG-59 and RG-62 coaxial cable. Frequency range 0 to 50 MHz. The MHV interface features an extended PTFE insulator that physically prevents mating with standard BNC jacks - a deliberate safety barrier that keeps high-voltage lines from being cross-connected to low-voltage equipment.
Key Features
- Connector type: MHV (Miniature High Voltage) - right angle, 90-degree body
- Gender: Plug (male pin)
- Voltage rating: 5,000 V peak
- Current rating: 5 A maximum
- Frequency range: 0 to 50 MHz
- Impedance: Non-constant (not suitable for constant 50-ohm or 75-ohm RF applications above 50 MHz)
- Cable compatibility: RG-59, RG-59/U, RG-62, RG-62/U
- Termination: Solder center contact, mechanical braid clamp
- Body: Brass with nickel plating
- Contact: Brass with silver plating
- Insulator: TFE / PTFE (Teflon)
- Mating interface: MHV female jack only - incompatible with BNC and SHV connectors
Applications
- Assembling the high-voltage signal line between a Geiger-Müller or scintillation detector and a NIM bin power supply - where the right-angle body routes stiff RG-59 cable around rack-mount instrument panels without overstressing the cable
- Connecting a high-voltage DC bias supply to a vacuum chamber feedthrough on a sputter deposition or plasma etch system, where a straight connector would protrude into the equipment footprint and risk impact or cable strain
- Building custom hipot and dielectric breakdown test leads for calibration labs - the MHV interface physically prevents accidental connection to low-voltage instrument inputs
- Replacing aging MHV plugs on proportional counters, photomultiplier tube bases, and ionization chamber assemblies during lab refurbishment
- DIY builders assembling Farnsworth-Hirsch fusors or homebrew radiation detectors who need a proven 5 kV-rated coaxial termination on RG-59 runs
Frequently Asked Questions
Will this mate with a standard BNC connector or jack?
No. The extended PTFE insulator on the 000-28100 physically prevents mating with standard BNC jacks. This is intentional - it ensures high-voltage lines cannot be cross-connected to low-voltage equipment. This connector mates exclusively with MHV female jacks.
What cables does this connector fit?
Designed for RG-59, RG-59/U, RG-62, and RG-62/U coaxial cable. Compatible Belden equivalents include 8221, 8241, 9169, 9204, 9228, and Canare LV-61S.
Is the straight-body version of this connector available separately?
The straight-body equivalent is Amphenol 000-28000. This listing is for the right-angle (90-degree) 000-28100 only.
What tools and skills does assembly require?
Soldering iron and solder for the center contact, and standard wrenches to tighten the mechanical braid clamp. Precise cable stripping dimensions are required - clamp-style assembly is more involved than a crimp connector. Standard coaxial termination skill level applies.
Are there modern lab safety concerns with MHV connectors?
Some facilities have moved to SHV (Safe High Voltage) connectors, which feature a recessed pin design that prevents contact with the male pin while energized. The 000-28100 is MHV, not SHV - they do not mate with each other. Buyers should confirm whether their facility's safety guidelines permit MHV interfaces before ordering.
Old-stock Amphenol hardware from a government lab - every part of the assembly is there, the nickel is still bright, and the PTFE has never seen a cable. Somewhere there is a detector waiting on exactly this connector.
