Feedthroughs
We offer hundreds of different feedthroughs for many different applications, the main categories are as follows:
Multipin Feedthrough
Traditional multipin designs are provided with threaded circular connectors which allow moderate pin density. These feedthroughs are offered in 3, 5 and 7 pin versions, and are rated to 500 volts and 3.5 amps per pin.
MS multipin is provided with industry standard threaded connectors which meet MIL-C-5015 specification, and are designed to meet similar applications. These feedthroughs are offered in 4 to 35 pin versions, and are rated for 700 volts and 10 amps per pin. Single-ended versions offer a connector for the air side. Double ended versions offer both air and vacuum side connectors.
ThermoCouple
Thermocouple is the description for electrical feedthroughs that are commonly used for temperature measurement systems. A thermocouple feedthrough does not measure temperature, but rather it is used to conduct the thermocouple’s voltage signal from inside the vacuum system to an external instrumentation device. MPF uses ceramic-to-metal sealing technology to braze various metals used in thermocouple assemblies to high purity alumina ceramic insulators. Thermocouple feedthroughs are suitable for ultra high vacuum applications.
MPF offers several mounting options for all standard products: Weldable, Quick Flange (QF), and Conflat Flange (CF). Most designs are also configured for Baseplate and NPT style adapters. Custom adapters, plates and flange configurations are available by request.
Power
Power is the description for electrical feedthroughs used for the transmission of high voltages and/or high current into vacuum systems. Power feedthrough options include many variations of design which offer a broad range of voltage and current. High purity alumina ceramic insulators provide electrical isolation and various conductor materials offer specific current capacities.
MPF offers several mounting options for power feedthroughs: Weldable, Quick Flange (QF), Conflat Flange (CF), and Baseplate (BP). Baseplate versions of power feedthroughs are commonly used in vacuum furnaces and vacuum coating applications. Many designs are also configured for NPT style adapters. Custom adapters, plates and flange configurations are available by request.
Breaks
Breaks are tubular electrical isolators which are composed of metal adapters brazed to both ends of a ceramic insulator. These assemblies are used primarily for voltage isolation. Assemblies with inner diameters less than 2.5 inches are typically referred to as breaks, and those with larger inner diameters are called envelopes. MPF offers several mounting options for breaks and envelopes: Weldable, Quick Flange (QF), and Conflat Flange (CF). Custom adapters, plates, and flange configurations are available by request.
