!Note
PTFM Series 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 Series is suitable
for use as an air temperature sensor.
1. PTFM Series is a screw-fixing type and PTFL Series is a
2. Compact and light design as well as excellent
3. Solid-state construction withstands mechanical
4. Contactless operation provides a prolonged service
5. The operating point of "POSISTOR" is set on the
6. PTFM Series and PTFL Series have the same temperature
