LF 306 – Industry current sensors
The LF 306 current sensor family is intricately crafted to meet the demands of industrial applications. Tailored for the precise measurement of DC, AC, and pulsed currents, these sensors ensure galvanic isolation between the primary and secondary circuits.
Characterized by a compact and ultra-flat design, the LF 306 electronic components excel in accuracy and exhibit swift response times. They are adaptable for panel mounting in various configurations, featuring a 25.5 x 25.5 mm aperture for the primary conductor crossing. Additionally, the LF 306-S/SP10 variant can also be installed on a printed circuit board (PCB).
These current sensors leverage closed-loop Hall effect technology, bolstering their accuracy and reliability in industrial applications.
