HLSR Series

The perfect fit for your design.

HLSR - Current Sensors

The HLSR current sensors are meticulously engineered for precise electronic measurement of DC, AC, and pulse currents, all while ensuring galvanic isolation between primary and secondary circuits.

These sensors offer versatility, available in five different current measurement ranges: 10 ARMS, 20 ARMS, 32 ARMS, 40 ARMS, and 50 ARMS, with a measuring range extending up to 2.5 times Ipn, ensuring high accuracy.

Designed exclusively for PCB mounting, HLSR electronic parts come in two versions: HLSR-P for through-hole mounting and HLSR-SM for surface mounting.

Notable features of the HLSR family include access to voltage reference, low offset and gain drift, short response time, and a voltage output. Additionally, they boast a compact and unique design, occupying only 3.87 cm² of surface area on the PCB and standing at a mere height of 12 mm.

For digital output needs, HLSR sensors are also available in the HLSR Digital family.

Operating on open-loop Hall effect sensor technology, HLSR sensors are ideally suited for industrial applications requiring precise and reliable current measurements.
