High current compatible compact/thin current sensor "CZ375x series"

High current compatible compact/thin current sensor "CZ375x series"

Achieving miniaturization of EV charging stations and increasing output capacity! Coreless current sensor capable of detecting ±225A with surface mount.

The CZ375x is a magnetic coreless current sensor that incorporates Hall elements. By using high-sensitivity Hall elements, it can accurately measure a wide current range of ±115A to ±225A, which is difficult to achieve with typical coreless current sensors. Continuous current flow is also possible up to 100Arms. Therefore, it contributes to "increased output capacity." Additionally, compared to shunt resistors and core-type through-hole sensors, it can contribute to "miniaturization" and "reduction of manufacturing costs." ■ Miniaturization - Due to its small size and surface-mount package, it can be mounted on the back side of the circuit board. - The primary conductor has low resistance (0.27mΩ), which suppresses heat generation, allowing it to be placed in limited space on the circuit board. * It generates one-third the heat of other companies' coreless current sensors (based on our comparative test data). ■ Reduction of manufacturing costs It contributes to reduced manufacturing (assembly) costs by eliminating the need for wire connections to through holes. * For more details, please refer to the PDF document or feel free to contact us.

High-speed response compact/thin current sensor "CZ3Axx series"

High-speed response compact/thin current sensor "CZ3Axx series"

Contributing to the improvement of system safety! Coreless current sensor with built-in high-speed, high-precision overcurrent detection function.

CZ3Axx is a magnetic coreless current sensor with built-in Hall elements and overcurrent detection functionality. It achieves a high-speed response of 1μs and high precision of 0.3% F.S., enabling the detection of various fault modes such as ground faults and arm short circuits, contributing to improved system safety. Additionally, through its unique packaging technology, it realizes a low primary conductor resistance of "0.27mΩ" and high insulation with a creepage/clearance distance of ≧8mm. This significantly reduces heat generation during current application compared to shunt resistors, and eliminates the need for a primary side power supply or amplifier for insulation, allowing overcurrent detection with just the IC. Therefore, it can be placed in limited spaces on a circuit board. *For more details, please refer to the PDF document or feel free to contact us.

[Use Case] Detection of Drill Breakage Precursors [Failure Precaution Detection / Equipment Maintenance]

[Use Case] Detection of Drill Breakage Precursors [Failure Precaution Detection / Equipment Maintenance]

Constantly monitoring graphs! Introducing a case study that reduced unexpected stoppages on the production line.

We would like to introduce a case where the AC current sensor from "ParaRecolectar" was used to detect signs before the drill breaks. In deep hole machining, drills were either replaced regularly or after they broke, leading to sudden equipment stoppages due to unexpected drill breakage. By applying this case, it becomes possible to detect different waveforms during normal operation and send a stop signal to the equipment, allowing it to be halted before the tool breaks. [Case Overview (Partial)] ■Challenges - Want to know the signs before the drill breaks in the machining equipment - Prevent sudden equipment stoppages ■Implementation Method - Measure the spindle motor current of the machining equipment with an AC current sensor *For more details, please download the PDF or feel free to contact us.
