POSISTORr for Circuit Protection for Overheat Sensing Lead Type PTFM type has been developed for protecting power transistors, stereo main amplifiers, etc. from overheating, and also for sensing the temperature of other components which may be overheated. The "POSISTOR" offers an excellent temperature sensing ability, exhibiting a steep change in electrical resistivity near the temperature setting. PTFL type is suitable for use as an air temperature sensor. s Features 1. PTFM type is a screw-fixing type and PTFL type is a lead type, therefore mounting is easy. 2. Compact and light design as well as excellent thermal response 3. Solid-state construction withstands mechanical vibration and impact sufficiently 4. Contactless operation provides a prolonged service life, yet permits noiseless operation. 5. The operating point of "POSISTOR" is set on the steepest point along the resistance-temperature characteristic curve, thus performing the overheat protective operation securely. 6. PTFM type and PTFL type have the same temperature characteristic, providing a selection depending on the mounting method. 3.5 ±1.5 4.0 max. ø0.5 ±0.05 (in mm) 5.0 max.
