The LEM HTFS 400 P is a high-performance open loop Hall effect current sensor engineered for measuring AC, DC and pulsed currents up to ±600 A with a 600:1 ratio. Designed as a compact PCB mounted module with a 22 mm bore, it delivers galvanic isolation and ratiometric voltage output on a stable 5 V supply. With its robust temperature range and fast response, the HTFS 400 P offers reliability in a variety of low voltage industrial applications.

Why Choose the LEM Hall-Effect Current Sensor?

Choose the HTFS 400 P when you need a compact yet accurate sensor that ensures safe and efficient current measurement up to 400 ARMS (nominal, max ±600 A). Its open-loop Hall effect design offers fast 3–7 µs response, excellent repeatability (±1% accuracy), and true galvanic isolation—making it ideal for automation, drives, instrumentation, and power management systems.

Product Functional Highlights:

Measures AC, DC and pulsed currents up to ±600 A with a 600:1 ratio
Open loop Hall effect design providing galvanic isolation between primary and secondary circuits
Ratiometric voltage output on a regulated 5 V unipolar supply
High accuracy (±1 %) and linearity (±0.5 %) over wide dynamic range
Fast response time (~3.5–7 µs) suitable for dynamic load monitoring
Compact PCB mount configuration with 22 mm aperture and four 3.5 mm mounting holes; minimal footprint (approx. 40 × 46 × 17 mm).
