iHighly reliable Hall Effect device

iCompact and light weight. Two sensors in one package

iFast response time

iExcellent linearity of the output voltage over a wide input range

iExcellent frequency response (> 50 kHz)

iLow power consumption (24 mA nominal)

iCapable of measuring both DC and AC, both pulsed and mixed

iHigh isolation voltage between the measuring circuit and the

current-carrying conductor (AC2.5KV)

iExtended operating temperature range

iFlame-Retardant plastic case and silicone encapsulate, using

UL classified materials, ensures protection against

environmental contaminants and vibration over a wide

temperature and humidity range
