Caution: Ensure routing avoids sharp bends or kinks that could impact impedance, especially near connectors.

Buying Guide: SHV To SHV Cable Essentials

What to consider when choosing SHV to SHV cables:

• Impedance and voltage rating. Look for 50 ohms impedance and a voltage rating that matches your highest operating voltage (e.g., 5 kV or higher).
• Connector compatibility. Ensure SHV ends match your equipment; some cables include RP-BNC or BNC variants for versatility.
• Cable length. Choose a length that minimizes clutter while allowing safe, unobstructed connections on your bench.
• Cable construction. RG223 coaxial designs are common for high-frequency HV work; confirm shielding and insulation meet your safety and performance needs.
• Durability and handling. Consider cables with robust strain relief and secure connector latches if your setup involves frequent movement.

Practical scenarios

Best for Thorlabs piezo amplifiers: Short to medium-length cables with SHV connectors ensure clean, low-loss connections with minimal interference.

Best for lab benches with limited space: Short cables help reduce clutter; RP-BNC to BNC variants are handy for quick changes between measurement tools.

FAQ

1. What does SHV stand for and why is it used in high-voltage cables?
   SHV is a Safe High Voltage connector designed to withstand high voltages with secure, low-impedance connections suitable for lab gear and piezo amplifiers.
2. Are these cables suitable for Thorlabs equipment?
   Yes, several selections explicitly mention compatibility with Thorlabs piezo amplifiers and similar SHV-interface devices.
3. Should I choose RP-BNC or BNC variants?
   RP-BNC variants are useful when you need quick coupling to RP-BNC ports; choose BNC when your equipment uses standard BNC. Verify your device connectors before purchase.
4. What length should I pick for a busy lab bench?
   For dense benches, shorter lengths (50 cm to 1 m) reduce clutter; for spread-out rigs, 2–5 m options provide needed reach.
5. Is RG223 the only suitable coax for SHV cables?
   RG223 is common due to its high-voltage tolerance and shielding, but confirm the specific impedance and insulation requirements for your setup.
