Overview

Ultra-high vacuum coaxial feedthroughs enable stable, high-quality signal transmission, making them ideal for applications that demand stringent signal integrity.

BNC

Standard BNC feedthroughs offer a cost-effective, universal coaxial solution for reliable signal transmission across scientific research, industrial manufacturing, aerospace, and other fields. A key feature of BNC connectors is their quick-connect capability. However, standard BNC feedthroughs do not provide fixed impedance matching. The BNC50 series, developed from standard BNC feedthroughs, offers 50Ω impedance matching to minimize signal loss during transmission.

SMA

SMA feedthroughs are widely used in scientific research, industrial production, and communications due to their high-frequency transmission capability, compact design, and flexible configurations, ensuring efficient and reliable high-frequency signal transmission in vacuum environments. With 50Ω impedance matching, SMA feedthroughs support even higher frequency signals.

MHV

MHV (Miniature High-Voltage) coaxial feedthroughs are a variant of BNC, featuring recessed pins with a voltage rating of up to 5 kV.

SHV

SHV feedthroughs are high-voltage coaxial connectors designed for the safe transmission of high-voltage electrical signals, with a maximum voltage of 5000 V DC. Their design ensures safety and reliability under high-voltage conditions, making them suitable for scientific research, industrial equipment, and aerospace applications. SHV10 and SHV20 are higher-voltage versions: SHV10 handles up to 10 kV, while SHV20 supports up to 20 kV, enabling transmission of even higher voltage signals.

Type-N & 7/16

Both Type-N and 7/16 coaxial feedthroughs use threaded fastening for robust construction and excellent RF performance, making them widely used in vacuum systems requiring high-power and high-frequency signal transmission. Both offer 50Ω impedance matching. Type-N feedthroughs are ideal for higher-power high-frequency signals, while 7/16 feedthroughs suit medium- to high-power microwave transmission. Note: 7/16 feedthroughs are only compatible with KF or ISO flanges for use in high-vacuum environments.

TRIAX

Triaxial feedthroughs are designed for high-precision transmission of low-current, low-voltage signals. Their unique triple-coaxial structure effectively reduces signal interference, ensuring signal integrity and accuracy. They are suitable for applications where high power is not required but signal quality is critical. Note: The atmospheric-side and vacuum-side interfaces of triaxial feedthroughs are identical, using the same connectors.
