New product! Compact and lightweight servo-type DC low current sensor & compact clamp-type AC current sensor.
Our company, which has developed around 600 types of current sensors, is introducing new products! ■ The 'DCS-20-AS Series' is a compact and lightweight servo-type DC low current sensor. It can measure minute DC currents with high precision and non-contact. ■ The 'CTU-8CLS (patented)' is a compactly designed current sensor with a clamp mechanism positioned inside the frame. It is ideal for measuring AC currents using vinyl insulated wires with an outer diameter of less than 8mm. More new products will be launched soon! Additionally, we have confirmed our participation in an exhibition. Please come and see the actual products! 【JECA FAIR 2014 - 62nd Electrical Industry Exhibition -】 Date: May 28 (Wed) - 30 (Fri), 2014 Venue: Intex Osaka (Booth No: 5-25) http://jecafair.jp/

![[Current Sensor Related] S21S Series](https://image.mono.ipros.com/public/product/image/c9c/2000128263/IPROS2290407326325927876.jpg?w=280&h=280)
This is the "S21S" series of current sensor-related products. They can be used in inverters, motor control, UPS, and welding machines!
<Rohs Directive Compliant Products> The "S21S" series of current sensor-related products can be used in inverters, motor control, UPS, and welding machines. They feature a low-cost magnetic balance type/current output type, with a mounting structure that includes connectors, a primary conductor that is through-type, a rated current of 180A, and a power supply voltage of ±15V. The Hall current detector measures current non-contact by combining a magnetic core and a magnetic sensor (Hall element) that generates magnetic flux proportional to the current, resulting in no voltage drop for measurement, excellent insulation, and the ability to measure alternating current, direct current, and mixed currents, making it an ideal device. The magnetic flux generated proportional to the current If is concentrated by the iron core and passes through the Hall element inserted in the gap, outputting a voltage according to the Hall effect described by the formula Vh = k ・ Ic ・ B.
