TDK Presents Robust and Easy-to-Mount NTC Systems
TDK Corporation has expanded its NTC temperature sensor portfolio with the M704 and M705 series, engineered for reliable temperature measurement in high-voltage industrial environments. These new probe assemblies are designed to provide safe and precise monitoring in demanding applications, with the M704 offering voltage ratings up to 4000 V (AC) and the M705 up to 2500 V (AC).
These NTC systems are crucial for applications such as UPS and PSU systems in data centers, charging stations, and PV inverters, where safety, reliability, and installation efficiency are paramount. By combining electrical robustness with ease of assembly, TDK aims to help designers achieve safe and efficient system operation in these challenging high-voltage settings.
The M704 and M705 series differentiate themselves through their application-focused design. The M704 supports automated PCB integration with its compact plastic case, while the M705 features a metal-tag ring lug design for excellent thermal coupling and flexible screw-on mounting, ensuring robust and adaptable temperature sensing solutions.
