feedthrough connectors
The feedthrough and current input terminal are mounted on airtight containers and used to carry electricity (signal or power supply) in and out while retaining airtightness. The feedthrough is usually multipolar and has an allowable current range for signals to the 46A/pin and withstand voltage of up to AC 1500 V. The key feature is that it can be connected using an MIL-standard MS connector to be compact.

The current input terminal is mainly intended for use with high withstand voltage or high current. Different combinations are available for this item. For example, a basic terminal (single pole) can be directly welded to a chamber for use, or multiple terminals are welded to a flange for use as a multipolar current input terminal.
