Product Overview
Industrial Components Products (I.C.P.) part number 29100 is a Miniature High Voltage (MHV) straight male cable plug rated for coaxial cable assemblies carrying up to 5,000V peak. The body is silver-plated brass - a construction choice you rarely see on MHV connectors today, where chrome plating is the norm. The center pin contact is beryllium copper. An extended fluoropolymer dielectric sleeve protrudes past the outer shell to reduce flashover risk and minimize accidental contact hazard. Bayonet-style coupling locks quickly and securely. Fits RG-58, RG-58A, and RG-58C cable.
Key Features
- MHV (Miniature High Voltage) straight male cable plug configuration
- 5,000V peak operational voltage; 3,000V RMS working voltage
- 50 Ohm nominal impedance
- Silver-plated brass body - uncommon construction, not chrome
- Beryllium copper male center pin contact
- Extended fluoropolymer dielectric sleeve minimizes flashover and accidental shock hazard
- Bayonet-style coupling interface for quick, secure locking
- Compatible with RG-58, RG-58A, RG-58C, and equivalent small-diameter flexible coaxial cable
Applications
- Lab technician terminating RG-58 cable for a high-voltage power supply output connection in a physics research setup
- Instrumentations tech repairing or replacing connectors on X-ray system HV signal lines where BNC connectors are not rated for the voltage
- Builder assembling a scintillation counter or scintillation pre-amplifier cable harness that calls for MHV interfaces on the detector side
- Hobbyist building or restoring a Geiger counter or radiation detection instrument requiring a period-correct MHV plug on the coaxial run to the probe
- Maker sourcing a compact high-voltage coaxial termination for vacuum tube or plasma experiment wiring where the fluoropolymer sleeve adds a real safety margin
Frequently Asked Questions
Will this connector mate with a BNC or SHV jack?
No. MHV, BNC, and SHV connectors look similar but are mechanically incompatible with each other. Attempting to force an MHV plug into a BNC or SHV receptacle can damage equipment and create a serious shock or arcing hazard given the voltage levels involved. This connector mates only with a compatible MHV female jack or receptacle.
What cable does this fit?
RG-58, RG-58A, and RG-58C, and equivalent small-diameter flexible coaxial cable. It is not designed for larger-diameter coax.
Is this primarily a low-frequency connector?
Yes. MHV connectors are designed for high-voltage DC and low-frequency applications. They are not the right choice where strict impedance matching at RF frequencies is required - impedance is not constant across frequency in MHV designs.
What termination method does this connector use?
The connector accommodates clamp, crimp, or solder termination methods standard to MHV male plug assembly.
Silver plating on an MHV connector is genuinely unusual - most of what you find today is chrome. This one came out of a government research lab, which explains the spec. If you are building something that deserves the better material, here it is.
