FAQ

Q: What is the working principle of an open-loop Hall effect current sensor?

A: The open-loop Hall effect current sensor works based on the Hall effect principle. The magnetic field generated by the measured current is detected by the Hall element, which outputs a voltage signal proportional to the magnetic field strength. Electrical isolation between the primary and secondary is achieved through magnetic circuit coupling, requiring no direct electrical connection, ensuring safety and reliability.

Q: How to apply for samples? What is the lead time?

A: You can submit a sample application through our website or email. Please provide your company information and target model. Samples are free of charge and will be shipped within 3-5 working days. Mass order lead time is generally 2-8 weeks.
