b. Thermal guard "OHD®" is popularly used for anti-overheat sensor. It contributes to easy circuit designing as it is compact and light weight, designed to function simple and reliable ON/OFF operation at the predetermined temperature and able to function in the signal power range between 0.1mW to 6W(*1). Moreover, compared to bimetals, response is approx. 2 times superior and because the contacts are glass-sealed, it has excellent dust proof, ignition proof and corrosion resistance property. (*2)Also, as it is International safety standards (UL, TUV, CSA) certificated,
It accommodates to expanding international market as the globalization of the production accelerates (*1: OHD5S-__B, OHD5D-__B and OHD5R-__B are MAX 1W / *2: Based on NEC Tokin test data )
