Single Sided Self Regulating Heaters
MS has developed a revolutionary design in PTC heater
technology that vastly simplifies the connection between
the PTC element and the medium to be heated. Most
heating elements, including PTCs, are live electrically on
both sides of the element. This makes the fabrication of the
assembly more difficult and, without special precaution,
permits potentially hazardous voltages to be a danger to
the end user. With the single sided heater design, the bottom side of the thermistor element is electrically isolated
from the top side. However, the transfer of heat is not
affected by this design. PTC elements can be soldered,
epoxied or spring mounted to its interface. As with other
PTC heaters, the single sided PTC is self-regulating when
operated above its switch temperature. Please contact the
factory for specific design or application information or
the availability of options.
