The detector is electrically isolated from the input and performs like an ideal isolated FET designed for distortion-free control of low level ac and dc analog signals. The H11F series devices are mounted in dual in-line packages.

TEST EQUIPMENT KELVIN CONTACT POLARITY HUF HUF t Ig TO A&B FOR PARAMETER | POLARITY 1 SENSING C&D FOR POLARITY 2 HIIFI HUF ST2063 In many test equipment designs the auto polarity function uses reed relay contacts to switch the Kelvin Contact polarity. These reeds are normally one of the highest maintenance cost items due to sticking contacts and mechanical problems. The totally solid-state H11F eliminates these troubles while providing fas- ter switching.
