Elastomer Seals
Sealed connectors are fitted with O-rings and cable sealing gaskets. For O-rings, the standard material are:
Please note that as an elastomer reaches its lower temperature limit, it becomes rigid and loses the flexibility required for
connector mating and unmating. If sealed connectors have to be manipulated at low temperatures, the O-ring in the mating
area has to be of a material with a considerably lower temperature limit.
The elastomers listed below represent presently available materials, which FISCHER can substitute when required by an
application. Not all materials are available in all shapes and sizes so please check with us for details.
Operating Temperatures
The temperature ranges quoted by the manufacturers of the plastic materials are usually the absolute maximum values.
When exposed to the mechanical and electrical stresses present in a connector, these values are often unrealistic.
If a composite connector system including accessories is used, then the item with the lowest temperature performance will
dictate the operating temperature limit of the system.
