Sensors OHD™ Series Thermal Guard Overview Applications The OHD™ Series Thermal Guard is developed for thermal problem countermeasures and safety standard conformity, which are becoming increasingly important for electronic devices in recent years. 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. Benefits • Extremely simple circuit design • High reliability for on/off operations • Compatibility with extremely low (0.1 mW or lower) signals to high power (6 W) levels • Compact, light and easy to handle • Dust, explosion and corrosion-proof • High-speed response • Wide range of operating temperatures available in 5°C increments from +30°C to +120°C Ordering Information OHD 1- 40 B Series Model Number Operating Temperature (°C) Contact Type OHD 1 3 5R 30 35 40 45 50 55 60 65 70 75 80 85 90 95 100 105 110 115 120 B = Break M = Make (OHD1 and OHD3 Series only) © KEMET Electronics Corporation • P.O.
