Q: What is the difference between open-loop and closed-loop Hall current sensors?
A: Open-loop sensors directly amplify and output the Hall voltage. They offer simple structure, lower cost, and fast response, suitable for general industrial measurement. Closed-loop sensors use a compensation winding to generate an opposing magnetic field, offering higher accuracy and lower temperature drift. The HKC-LBS5 series open-loop design offers better cost-performance, suitable for most industrial applications.
Q: What is the output voltage range of this sensor?
A: The rated output voltage is 0.625V ±1%, corresponding to the rated measurement current of 300A. The output signal varies linearly with the measured current and can connect directly to PLC, DCS, or ADC sampling circuits.
Q5: 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.
