Touch-safe Loop Heater (Semiconductor)
LTS 064 | 20 W, 30 W, 40 W

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


Compact heater for the protection of electrical and electronic components in enclosures. Its design ensures good self-convection, effecting in high warm air flow. A touch-safe plastic cover provides for low surface temperatures on the side of the device. The practical push-in clamping terminal enables quick and easy electrical connection. The heaters are designed for continuous operation.
