OHD1-120B屬于傳感器變送器的溫度傳感器-溫控器-恒溫器-機械式。由基美公司制造生產的OHD1-120B溫度傳感器 - 溫控器- 恒溫器 - 機械式機械式溫控器設計用于在溫度過高的情況下確保組件安全。當超過設備的開關溫度（可調，14℉ 至 500℉）時，該系列中的組件將斷開或閉合自身所在的電路。復位溫度范圍包括手動復位、單次以及 20℉ 至 440℉，額定電流為 0.045 A 至 25 A。

Overview

The OHD Thermal Guard is developed for thermal problem

countermeasures and safety standard conformity, which

are becoming increasingly important for electronic devices

in recent years.

Its unique proprietary design features a magnet and

a temperature-sensing soft ferromagnetic substance

called Thermorite?. The material’s magnetic flux density

decreases as the temperature increases turning it into a

paramagnetic substance at the Curie temperature.

Benefits

? High reliability for on/off operations

? High-speed response

? Long operational life

? Excellent environmental durability

? Compatibility with extremely low (0.1 mW or lower)

signals to high power (6 W) levels

? Extremely simple circuit design

? Compact, light and easy to handle

? Dust, explosion and corrosion-proof

? Wide range of operating temperatures available in 5°C

increments from +30°C to +130°C

? UL, CSA and TüV approved

? RoHS/REACH compliant

Applications

Typical applications include atmospheric temperature

detection and overheating monitoring of power transistors,

power modules, room heaters, hot gas heaters, PPCs,

amplifiers, motors, HDDs, FDDs and other general

appliances.
