LEM - IN 1000-SHF: Outstanding current sensor using Fluxgate technology

The IN 1000SHF is a new generation current sensor using advanced closed-loop Fluxgate technology, specifically designed for applications that require high performance, instant response, and absolute accuracy. The product offers a wide bandwidth of up to 2.5 MHz, with lightning-fast response, making it ideal for high-frequency measurement systems, high-speed motor control, or precision testing devices like test benches.

The IN 1000SHF is ultra-compact, with only a few ppm, providing near-perfect linearity, low thermal drift, and ensuring reliability even during long-term operation. Additionally, its latency is under 1 nanosecond, improving system response speed and supporting applications requiring micro-level time synchronization, such as modern power converters. The IN 1000SHF is designed with D-sub connector standards, LED status indicators, and a warning function, making it easy to integrate and operate safely in application devices.
