Current Sensors

Product catalog summary
Overview
The document provides a comprehensive guide on current sensors, detailing their specifications, applications, and features. It includes a network map of Tamura's global operations, highlighting sales, factory, and R&D locations.
Applications and Features
Current sensors measure currents from 1mA to 10k amperes, handling AC, DC, and AC+DC waveforms. Tamura's sensors use the Hall-Effect system, offering galvanic isolation and zero insertion loss. Applications include inverters, power conversion equipment, and renewable energy systems. Key features are fast response time, high reliability, and a current range of 3A to 1500A.
Circuit Systems
Three types of current sensor systems are described: Open Loop, Closed Loop, and Fluxgate. Open Loop sensors are cost-effective and compact, using a Hall element to convert magnetic fields into voltage. Closed Loop sensors offer higher accuracy with a secondary winding to cancel magnetic flux. Fluxgate sensors use a probe coil for high accuracy and temperature stability.
Application Notes
General considerations include careful handling of polar electronic components, using twisted or shielded cables to prevent noise, and ensuring proper connector material to avoid galvanic corrosion. Open Loop sensors may risk excessive heating with high-frequency currents.
Standards and Compliance
The document references compliance with UL508 and CSA C22.2 No.14 standards, ensuring safety and reliability in various applications.
Data Sheets
Specifications for F-Series, L-Series, and S-Series sensors are provided, including circuit systems, mounting configurations, and power requirements.
Specifications and Procedures
Closed Loop Sensors: Ensure balanced power supply voltage to avoid DC offset error. Exceeding maximum rated current can damage circuitry. Use stable temperature resistors for voltage conversion.
Flux-Gate Sensors: Compensation current varies with measured current. A 450kHz ripple voltage may be present; an external capacitor can be added if necessary.
Part Numbering System
Model types include open loop, closed loop, fluxgate, and one-chip ASIC systems. Mounting configurations include through-hole, surface mount, and bolt-on devices. Rated current is specified in amperes. Control power supply types include single and dual supply. Power supply voltage options are 5V and 15V. Special specifications include busbar, cover, and various connector options.
Important Notices
Product information is subject to change for improvements. Intended for general electronics, not for high-reliability applications like medical or safety devices. Users must verify safety in their designs to prevent accidents. Circuit examples are for reference; users must ensure compliance with intellectual property rights. Products are not designed for special environments or military applications. Compliance with export control laws is required. Contact Tamura for environmental compliance details.
Ratings and Models
Various models are listed with their primary and secondary ratings, including current, voltage, and power specifications. Environmental ratings specify maximum surrounding air temperature and pollution degree. Electrical ratings detail input and output specifications for different series models.
Technical Specifications
Detailed specifications for LA02P, LA03P, and LA01P series of current sensors are provided. These sensors are designed for high-speed response and compact size, suitable for various applications requiring precise current measurement.
General Notes
All series comply with RoHS standards and feature UL94 V-0 case materials for safety. Each series has specific terminal configurations and recommended layouts for optimal performance.

Outline / Applications / Features The current sensor is a sensor to measure the current as its name. However, The current is various. There is a current value up to 10k amperes treated in the power plant from 1 mA, and the shape of current waves also has AC, DC, and AC + DC. Since a method and a structure the best in each measuring object are different, there are also various current sensors. Tamura supplies the sensor using the Hall-Effect system for measuring the current value from several amperes to several kilo-ampere. The Hall-Effect current sensor measures the magnetic flux produced in...

TXV^rM^J^ CURRENT SENSORS Circuit system Tamura offers multiple current sensor options to meet application requirements: Open Loop or Linear type (magnetic proportionality); Closed Loop or Servo-type (magnetic balance); Flux-Gate (magnetic equilibrium). Open loop If the current is applied to the cable, the magnetic field proportional to the current in surroundings of the cable is generated on Ampere's rule. The magnetic core is set in surroundings of the cable to improve the sensitivity. The Magnetic field is converted into the voltage by the linear type - hall element is placed in the gap of...

When the polarity of the power supply is mistaken, the sensor is damaged. 2. Static electricity or excessive voltage can increase an offset voltage in the Hall element, and cause offset voltage to change. Please exercise care in handling and application. 3. In order to prevent the influence of noise, the use of twisted cable or shielded cable for the output line is recommended 4. If using this device within a magnetic field generated by other devices, the...
