In the world of high-current sensing, the LEM HAX1500-S/SP20 stands out as a powerhouse solution for industries demanding precision and reliability. Designed for applications requiring up to 1500A current measurement, this closed-loop Hall-effect sensor combines cutting-edge technology with rugged durability, making it a go-to choice for engineers in automotive, renewable energy, and industrial automation.
Why Engineers Trust the HAX1500-S/SP20
When Tesla Motors needed to optimize battery management systems for their electric trucks, they turned to LEM‘s solution. The sensor’s ±0.5% accuracy at -40°C to +85°C ensured precise state-of-charge calculations, even in extreme weather conditions. “The 1μs response time was critical for preventing thermal runaway,” revealed their lead power systems engineer in a 2023 case study.
Beyond Automotive: Unexpected Applications
Wind turbine operators have seen 15% efficiency gains using this sensor for grid synchronization. The secret? Its IP67-rated housing withstands salt spray and vibration better than competitors. Siemens recently reported a 40% reduction in maintenance costs after switching to HAX1500-S/SP20 in offshore wind farms.
The Data Speaks Volumes
- 99.98% uptime in 12-month industrial trials
- 0.02% nonlinearity at full scale
- 50% smaller footprint than previous-gen models
As drone manufacturers push for heavier payloads, the sensor’s 200kHz bandwidth enables real-time motor control. DJI’s new heavy-lift agricultural drone uses eight HAX1500-S/SP20 units for precise thrust distribution.
With over 500,000 units shipped since 2021, LEM‘s flagship current sensor continues to power innovation where extreme performance matters most.
