HLSR-20-P Description

Short technical summary and product information.

The HLSR Series current sensors from LEM are engineered for accurate electronic measurement of DC, AC, and pulsed currents, providing essential galvanic isolation between primary and secondary circuits. Utilizing open-loop Hall-effect technology, these sensors deliver reliable performance across various industrial applications.

The HLSR Series supports multiple current ranges, including 10, 20, 32, 40, and 50 ARMS, with a measurement capability extending up to 2.5 times the nominal current (Ipn) for high accuracy under dynamic conditions. All sensors in this series are designed exclusively for PCB mounting, available in through-hole (HLSR-P) and surface-mount (HLSR-SM) versions. Their compact design occupies minimal PCB space (3.87 cm²) with a low profile (12 mm height), making them ideal for space-constrained applications.

Variants within the HLSR Series offer either analog voltage output or digital output. Analog versions provide a voltage reference with low offset and gain drift. Digital output variants feature an integrated Sigma-Delta Modulator, delivering a Pulse Density Modulation (PDM) bitstream for enhanced precision and flexible signal processing. These digital options support interfaces such as 2-wire CMOS, 2-wire RS422 Manchester, and 2-wire LVDS Manchester, covering current measurement ranges from 16 ARMS to 50 ARMS.
