They can make or break your equipment, putting lives at risk. Beyond considering a product’s operating temperature, it’s important to assess the performance of connectors and cables in their specific operating environment.
Fischer Connectors offers not only standardized products that operate within certain temperature ranges, e.g. from -55°C to +135°C for the ultra-rugged Fischer UltiMate™ Series, but also customized solutions designed to reach much higher or lower temperatures for dedicated applications.
In cold environments, choosing the right materials and connector configuration matters. Since connectors often freeze and crack, connectors enclosed in plastic and rubber are too fragile and let moisture in. Some metals are also unsuitable, as they fail to protect devices adequately from the elements. Although rarely used in extreme conditions, fiber optic is a good choice at low temperatures – e.g. to measure strain and temperature during powering tests on superconducting magnets at 1.9 Kelvin (see below), or along liquefied natural gas (LNG) pipelines down to -180°C.
