Product Overview
Kings Electronics KV-99-15 is a Safe High Voltage (SHV) straight coaxial inline barrel connector adapter built for high-voltage transmission up to 5,000V DC or 3,500V AC RMS. The SHV design features deeply recessed center socket pin contacts inside a protruding PTFE dielectric insulator sleeve - a deliberate safety geometry that prevents accidental contact with live conductors when un-mated. Housing is nickel or silver-plated brass with silver-plated contacts and a bayonet-style coupling latch. Non-constant impedance design, optimized for low-frequency high-voltage monitoring pulses rather than broadband RF.
Key Features
- Operating voltage: 5,000V DC or 3,500V AC RMS
- Connector type: SHV (Safe High Voltage) straight coaxial inline barrel adapter
- Coupling mechanism: Bayonet-style latch
- Dielectric insulator: Fluoropolymer (PTFE) with protruding sleeve for contact protection
- Center contacts: Deeply recessed socket pin - prevents accidental high-voltage contact when un-mated
- Housing: Nickel or silver-plated brass
- Contacts: Silver-plated
- Impedance: Non-constant - optimized for low-frequency high-voltage pulse applications
- Safety design: Ground-first mating sequence; physically incompatible with BNC and MHV connectors
Applications
- Extending or adapting SHV cabling on a Geiger-Müller tube probe when routing cables through a panel or chassis wall in a radiation detection setup
- Connecting high-voltage power supply rails to detection electronics in nuclear instrumentation racks - where the SHV safety geometry is required by lab protocol
- In-line barrel joining of two SHV cables during bench configuration of particle physics detector chains
- Replacing a worn or corroded inline adapter on a high-voltage oscilloscope probe circuit or X-ray imaging power feed
- Makers and high-voltage hobbyists building Geiger counter kits or Tesla coil instrumentation who need a proper SHV barrel to complete a safe HV cable run
Frequently Asked Questions
Will this mate with my BNC or MHV connectors?
No. SHV connectors are deliberately engineered to be physically incompatible with BNC and MHV connectors, even though the bayonet coupling mechanism looks similar. This incompatibility is a safety feature that prevents accidental cross-mating with lower-voltage connectors. You need SHV-compatible plugs and receptacles on both ends.
Is this a bulkhead mount or a free-hanging inline connector?
The KV-99-15 is a straight coaxial inline barrel adapter - it connects two SHV cable ends in line. It is not a panel-mount bulkhead receptacle. The set screws visible on each end flange secure the cable or connector terminations.
What cable or termination type does this accept?
This connector is designed for SHV coaxial cable systems. Confirm that the termination style (solder, crimp) and cable diameter match your application before ordering.
Is this suitable for high-frequency RF use?
No. The SHV design is non-constant impedance, optimized for low-frequency high-voltage monitoring pulses. Applications requiring controlled impedance at high frequencies should use a different connector family.
High voltage demands the right handshake - a connector that keeps the hot pin buried until both sides are ready. The KV-99-15 has been doing exactly that in labs that don't forgive shortcuts, and now it's ready to do it in yours.
