Snap these heaters on a DIN rail inside your enclosure to keep electronics safe from cold and moisture.

Heaters with thermostat turn on when your enclosure gets too cold. Adjustable thermostats let you set a custom temperature. Nonadjustable thermostats switch on at preset temperatures to prevent unwanted or accidental changes.

Heaters without built-in control require a separate thermostat, humidistat, timer, or switch to activate.

Fan heaters blow hot air upward for even heat throughout an enclosure. They’re also double-insulated for shock protection.

Heaters that meet UL 94 V-0 self-extinguish within 10 seconds if they catch fire, and won’t spread the fire by dripping. An IP20 rating means fingers can’t accidentally touch the circuits inside and get shocked.

A sensor attached to the heater might signal that it’s warm enough near the heater, while other parts of the enclosure are still cold. Moving the sensor away from the heater helps you keep electronics warm and dry, anywhere in the enclosure. For even heat, a fan blows upward to circulate warm air.

Choose a heater that clips to DIN rail or one that mounts to the bottom of your enclosure. Add a sensor (sold separately) that reaches the part of your enclosure you need to keep warm.

Heaters with thermostats turn on when the enclosure gets colder than the temperature you set. Heaters with humidistats switch on to reduce condensation when the relative humidity gets too high.

Heaters meet American, Canadian, and European safety standards. They also meet UL 94 V-0, so if they catch fire, they self-extinguish within 10 seconds and won’t spread the fire by dripping.
