Single Feedthroughs
01 - Product Info
Single feedthroughs provide a solitary conducting path, ideal for applications that require both hermetic sealing and electrical isolation. These typically fall into one of four categories:
- High-voltage
- High-current
- High-power
- Instrumentation
In addition to maintaining hermetic integrity, many of our feedthroughs are designed to withstand extreme conditions, including high temperatures, cryogenic environments, high pressures, ultra-high vacuum, and chemically aggressive atmospheres.

Multi-pin Feedthroughs
01 - Product Info
In many vacuum system applications, it is necessary to introduce multiple low-level drive and signal circuits through a single interface. This can be achieved safely, efficiently, and cost-effectively using a single U.H.V flange equipped with multiple feedthroughs, mated to a secure plug that offers easy connect/disconnect.
For working voltages up to 3.5kV DC (pin-to-pin and pin-to-ground), a compact multi-pin socket can be used. This configuration allows a high density of electrical connections to be housed within a small-diameter vacuum flange, preserving space without compromising performance.
For higher voltage requirements, between 3.5kV and 10kV DC, individual single feedthroughs are required for each pin to ensure electrical isolation and safety.

Coaxial Connectors
01 - Product Info
We offer a wide range of coaxial connectors, available in four standard mating interface styles to suit both defence and commercial applications:
- BNC: 500V DC, 3A, 10¹³ Ω (at 1 kV DC), bayonet
- MHV: 5kV DC, 3A, 10¹³ Ω (at 1 kV DC), bayonet
- SHV: 10kV DC, 3A, 10¹³ Ω (at 1 kV DC), bayonet
- SMA: 700V DC, 1A, 10¹³ Ω (at 1 kV DC), screw
All coaxial connectors can be supplied for welding or screwing directly into vacuum flanges or chambers. Alternatively, they can be pre-welded into U.H.V, Klein™, or O-ring flanges, as single or multi-pin assemblies.
With the plug connected, the operating temperature range is -65°C to +165°C. When the plug is removed, the socket can be safely thermocycled to 450°C at a controlled rate of < 6 °C per minute. These miniature couplings are ideally suited for U.H.V environments, as well as high-temperature applications.

Thermocouple Feedthroughs
01 - Product Info
Accurate temperature measurement is essential in many vacuum applications. To support a broad range of operating conditions, we offer a comprehensive selection of Thermocouple and Thermocouple Power Feedthroughs, suitable for continuous use from -185°C to +1600°C.
All feedthrough conductors and connector contacts are manufactured from materials matched to the thermocouple type, ensuring accurate, error-free signal transmission. Standard designs support operating temperatures up to 400°C; where miniature thermocouple connectors are used, the maximum temperature is limited to 200°C.
All thermocouple feedthroughs are fully compatible with U.H.V environments.

Electrical Isolators
01 - Product Info
For applications where electrical isolation, mechanical strength, and environmental resistance are critical. All isolators are based on reliable ceramic-to-metal sealing technology.
Cryogenic Liquid/Gas Isolators: Compression-jointed ceramic-to-metal seals provide outstanding mechanical strength and resistance to thermal shock, making them ideal for use as isolators in cryogenic fluid and refrigerant systems where a voltage differential exists.
Small Diameter Isolators: These isolators, similar in construction to cryogenic feedthroughs, are suitable for use in vacuum systems or within liquid and gas feed circuits. They can be welded directly into customer equipment or supplied pre-welded into a variety of standard vacuum flanges.
Vacuum Breaks: Designed for larger-scale applications, vacuum breaks offer electrical isolation across vacuum lines and are available with static or rotatable flanges stainless steel flanges to simplify alignment during assembly. All designs are U.H.V compatible and suitable for repeated bake-out cycles up to 450°C.
Heat Sink Isolators: These isolators combine good thermal conductivity and excellent electrical insulation, making them ideal for applications requiring heat transfer across an electrically isolating barrier.

Sapphire Viewports
01 - Product Info
Our hermetic sapphire viewports are engineered for durability and performance in U.H.V environments. Single-crystal sapphire (melting point 2040°C) combines outstanding optical, mechanical, and chemical properties.
Sapphire features broad optical transmission, covering infrared, visible, and ultraviolet spectra:
- 0.2 - 0.4µm ~70% transmission
- 0.5 - 4.0µm ~85% transmission
- 5.0 - 6.0µm ~50% transmission
This makes sapphire viewports ideal for demanding diagnostic and monitoring applications. In addition to standard windows, bespoke sapphire lenses can be supplied to customer specifications.
