Touch-safe Loop-Heater (Semiconductor)
LT 065 | 50 W to 150 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 great convection resulting in excellent heat dissipation. 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. The heater is also available in a version with thermostat (LTF 065 series).
