POSISTOR r for Circuit Protection
Overheat Sensing Lead Type
5.0 max.
"PTFM Series" is a screw clamp type temperature sensor
which has been developed for sensing the temperature
of Transistors, Thyristors, stereo main ampli?ers, and
other devices having risk of overheat.
"PTFL Series" is a popular lead type temperature
4.0 max.

c Features
1. PTFM_S Series is ?xed easily to objects because of a
screw clamp type.
2. Compact and light design as well as excellent
thermal response.
3. Contactless operation provides a prolonged service
life, yet permits noiseless operation.
4. The operating point of "POSISTOR" is set on the
steepest point along the resistance-temperature
characteristic curve, thus performing the overheat
protective operation securely.
5. PTFM Series and PTFL Series have same resistance-
temperature characteristics, providing a selection
depending on the mounting method.
6. PTFM_S Series is certi?ed by UL/cUL/VDE.
It is suitable for a powersupply, etc, required the
safety standard.
