High Current
High Voltage
3 Pins
Medium Voltage
Water Cooled
Operating Ranges

Baseplate style operating temperature: −20 °C to 150 °C.

Type Voltage / Current Conductor # of Pins Operating Temp. Notes
Medium Voltage 10 kV / 25 A BeCu 1–8 −100 °C to 450 °C
Bake Temp:
CF flange up to 450 °C
KF flange up to 150 °C
High Voltage 100 kV / 180 A BeCu 1–4 −100 °C to 450 °C
High Current 12 kV / 600 A Cu, Ni, SS 1–10 −100 °C to 450 °C
Water Cooled 8 kV / 1,000 A Cu 1–4 −100 °C to 450 °C For continuous high current duty

Actual ratings depend on flange size, pin count, creepage/clearance, and environment.

High Current Conductor Selection
Conductor Current Capacity Corrosion Resistance
Copper (Cu) High Low
Stainless Steel (SS) Low Medium
Nickel (Ni) Medium High

Select based on required current, base pressure, and working gas.

Notes & Mounting Options

The key selection criteria are maximum operating voltage, maximum current per conductor, base pressure, and working environment (gas type and pressure). Standard high-power and high-voltage models in multiple ratings and flange styles are in stock.

Mounting options: Weldable, KF, CF, and Baseplate. Baseplate versions are commonly used in vacuum furnaces and coating applications. NPT configurations are available via adapters.
