Frequently Asked Questions
What is the difference between the wall sealing adapter and the glass sintering socket in terms of airtightness?
The wall sealing adapter has an airtightness leakage rate of 4.6 Pa·cm³/s under a pressure difference of 50.7kPa, whereas the glass sintered square disc sealed socket features a much higher airtightness with a leakage rate of only 0.1 Pa·cm³/s under a 152KPa pressure difference.
What materials are used for the contacts and insulators in these connectors?
For ordinary and through-wall sealing adapters, contacts are made of copper alloy (silver or gold plated) and insulators are thermoset materials. For glass sintered sockets, contacts are made of ferroalloy (nickel or gold plated) and insulators are glass body.
What is the mechanical life and environmental durability of these connectors?
These connectors feature a mechanical life of 1000 cycles. They can withstand vibrations up to 2000 Hz, constant acceleration up to 980m/s², and have salt spray resistance ranging from 96 hours (nickel/galvanized) up to 1000 hours (stainless steel passivated).
How does operating environment affect the withstand voltage?
At room temperature, both sealed and ordinary connectors withstand up to 1500V. Under moist and hot states, sealed connectors withstand 750V and ordinary ones withstand 1125V. Under low pressure (1kPa), both types withstand up to 300V.
What is the maximum operating temperature range for these electrical connectors?
The electrical connectors are designed for extreme environments, with an operational temperature range spanning from -55℃ to +200℃.
What is the electrical continuity performance between the connector shells?
The electrical continuity between enclosures depends on the material: it is 5.0 mΩ for aluminum alloy shells and 15 mΩ for steel shells.
