Current Sensors for PCB Designs

As the name suggests, a PCB-mount current sensor is a sensor designed to be mounted directly to a printed circuit board. A PCB design saves internal component space without losing sensing capabilities or other parameters, allowing engineers more component design flexibility.

Our dependable analog, open-loop current sensor module delivers accurate, non-intrusive, galvanically isolated AC and DC current measurements. Engineered for durability, it’s the perfect fit for high-power applications, offering seamless integration with circuit boards or standalone setups. With a broad current range of 200 to 1000 A, this sensor is ready to meet the demands of modern electrical systems.

Ideal for precise motor current sensing in electric vehicles (BEVs, HEVs, and PHEVs) and inverter modules for challenging industrial environments, it ensures reliable monitoring of drive systems and power distribution networks, boosting automation and operational efficiency.

 

Adaptable Current Sensor Design with Cost Savings

Hall-effect open-loop current sensors have the innate ability to isolate and convert complex signals such as AC and DC currents. This type of isolation is a common choice for inverter modules or battery monitoring, however, many of these board designs feature a vertical current sensor design. A vertical design can take up more space in the unit and requires the busbar to go around the PCB design.

CTS's current sensor features a through-hole configuration, enabling flush mounting directly onto a driver board. This design enables the busbar to pass through the PCB, establishing a direct connection between the power source and the motor while optimizing space efficiency. Additionally, the versatile design can accommodate various busbar geometries, ensuring compatibility with different system configurations and ultimately, reducing costs. This design supports functional safety options to ensure quality in automotive and industrial applications.
