Touch-safe Loop-Heater (Semiconductor)
LTF 065 | 50 W to 150 W

  • Clip fixing and pressure clamp for quick mounting
  • Low surface temperature
  • Earthed plastic casing
  • Wide voltage range
  • Integrated thermostat
  • Safe and stable performance under stressful conditions
  • Shock and vibration proof

Compact heater with PTC heating elements for heating enclosures. The heater prevents low temperature and thus condensation. Its aluminium profile is designed to achieve an optimised chimney effect, which ensures even distribution of warm air in the enclosure. The practical push-in clamping terminal enables quick and easy electrical connection. The heaters are laid out for continuous operation.
