Clamp-On Hall Sensor HKC-FK Series for Battery Supplied Applications and Industrial Control

The HKC-FK series snap-fit Hall effect current sensor is based on the open-loop Hall effect measurement principle, providing electrical isolation between the primary and secondary circuits. It accurately measures DC, AC, or pulse currents, with a rated input of up to 1000A. The product uses a snap-fit mounting structure that allows installation without disconnecting the cable under test, making operation convenient. Customisation of different rated input currents and output voltages is supported. It is widely used in variable speed drives, welding machines, battery-powered applications, UPS, and electrochemical applications.

Notes: Product specifications can be customized

Q: Does the snap-fit Hall current sensor require power-off during installation?

A: No. The HKC-FK series uses a snap-fit split-core structure that can be installed without disconnecting or removing the cable under test. It is especially suitable for retrofit projects and applications where power cannot be turned off, offering convenient installation.

Q: What is the working principle of an open-loop Hall effect 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: Does this product support customisation?

A: Yes. Customisation of different rated input currents and output voltage specifications is supported to meet diverse application requirements. Please contact our sales team for details.

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.
