AMWEI Screw Clamp PTC Overheating Sensing with Lug Terminal Features

  • Screw clamp type temperature sensor
    , for sensing the temperature
    of Transistors, Thyristors, stereo main amplifiers, and
    other devices having risk of overheat.
  • Limit temperature sensor with epoxy resin coating.
  • Tinned pin leads wire.
  • Metal lug tag screw clamp type easy mounting.
  • Metal tag lug permits good thermal coupling and
    thus short response time.
