The new 760 high temperature jacks and plugs from Switchcraft utilize a specially engineered, high RTI thermoplastic capable of withstanding much higher temperature and current than standard power jacks. This is ideal for applications with a high ambient temperature and is better able to withstand the high temperatures introduced by soldering than typical power jacks and plugs. They are made in the USA using the same high quality components as our standard power jacks and plugs and are fully mateable with either high temperature or standard jacks and plugs from Switchcraft.
