Current Sensors - D18XX, CS1XXX Series
Designed for use above 20 kHz, these sensors function
as the secondaries of a current transformer. The conductor 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. Applications 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 transformer versions with equivalent ratings, plus two 50/
60 Hz current sensors. To order, contact Coilcraft or
