Premo Hall-effect sensors feature input reference pin
Premo
DSR5 Hall-effect sensors
Premo has launched the DSR5 range of Hall-effect sensors with input reference pin, designed for a single supply voltage of 5V.
The DSR5 range is a close-loop technology component in a small package for THT mounting.
Primary winding allows the measurement of DC, AC and pulse currents on PCBs.
The external pin allows access to the internal reference (2.5V) and can be used as an output or input signal to be used by microcontrollers.
This series has been designed for nominal currents of 6, 15, 25 and 50A.
The multi-pin configuration allows a different range of nominal currents by connecting one, two or three pins in the primary winding.
