MHV Connectors

Compact, bayonet-lock RF connectors designed for high-voltage use

Overview

Amphenol RF’s MHV (Miniature High Voltage) connectors provide a standardized, rugged solution for high-voltage coaxial connections—supporting voltages up to 5,000 V DC. These bayonet-style connectors are ideal for systems requiring quick-connect capability without sacrificing safety or performance.

With nickel-plated brass construction, PTFE insulation, and built-in shock resistance, MHV connectors maintain reliable data transmission up to 300 MHz while safeguarding against voltage spikes and harsh conditions. Their mechanical durability and compact footprint suit labs, instrumentation, and high-voltage equipment.

Features and Benefits
  • High-voltage rating: Continuous service up to 1,500 V RMS and dielectric withstand to 5,000 V RMS—a robust option for high-voltage systems
  • Quick bayonet coupling: Quarter-turn locking mechanism enables fast, secure connections under pressure-driven usage
  • Rugged construction: Nickel-plated brass body with PTFE insulators and shock-resistant design ensures reliability under mechanical stress
  • Compact form factor: Smaller and lighter than full-size HV connectors, easing integration without clutter
  • Weather and dust resistance: Meets MIL-STD-348 guidelines—sealed in mated condition (non-hermetic) for reliable outdoor use
Key Technical Details
  • Impedance: Non-constant; designed for high-voltage applications rather than controlled RF impedance
  • Frequency Range: DC–300 MHz typical; suitable for high-voltage instrumentation and low-frequency RF systems
  • Voltage Rating: 1,500 V RMS continuous; 5,000 V RMS dielectric withstand
  • Connector Mechanism: Bayonet-lock quarter-turn securing, per MIL-STD-348
  • Mechanical Durability: Minimum 500 mating cycles for sustained field use
  • Materials: Nickel-plated brass shell; PTFE insulator; beryllium-copper contacts
Applications
  • High-voltage lab instrumentation (e.g., power supplies, X‑ray equipment, test benches)
  • Nuclear and radiation-detection systems (e.g., Geiger counters, scintillation detectors)
  • High-voltage transmission lines and cable assemblies
  • Military/industrial control instrumentation for HV signals
  • Outdoor systems requiring quick-connect high-voltage RF interfaces
