Current Sensors - D18XX, CS1XXX Series
Designed for use above 20 kHz, these sensors function
as the secondaries of a current transformer. The con-
ductor carrying the current to be measured is the “one
turn primary.” Sensitivity can be set at 1 Volt per Ampere
or at other desired values. It can also be doubled by
looping the conductor through the hole twice. Applica-
tions include sensing branch circuit overload, switcher
feedback, and detecting load drop or shutdown.
They come in a molded version (CS1XXX Series) or
encapsulated model (D18XX Series).
Coilcraft Designer’s Kit P403 contains samples of
the CS1050, 1100 and 1200 sensors, current trans-
former versions with equivalent ratings, plus two 50/
60 Hz current sensors. To order, contact Coilcraft or
