DIN-Rail Enclosure Space Heaters

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

With Adjustable Thermostat—Aluminum


Fan Heater with Adjustable Thermostat and Gray Plastic Housing	Fan Heater with Adjustable Thermostat and Black Plastic Housing

Adjustable thermostats let you set a custom temperature.

Heaters with thermostat turn on when your enclosure gets too cold.

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

IP20 Enclosure Rating—An IP20 rating means fingers can’t accidentally touch the circuits inside and get shocked.

UL 94 V-0—Heaters that meet UL 94 V-0 self-extinguish within 10 seconds if they catch fire, and won’t spread the fire by dripping.

Fixed thermostats switch on at preset temperatures to prevent unwanted or accidental changes.

Heaters with thermostat turn on when your enclosure gets too cold.

Enclosed Radiant Heater—Enclosed heaters have a plastic housing that makes them bigger than open heaters, but they don’t get as hot, so you can put them closer to other components. These heaters are double-insulated for shock protection.

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

Radiant Heating—Radiant heaters warm the air around the heater—use them for localized heat near batteries and other parts that don’t work well in the cold.

IP20 Enclosure Rating—An IP20 rating means fingers can’t accidentally touch the circuits inside and get shocked.

UL 94 V-0—Heaters that meet UL 94 V-0 self-extinguish within 10 seconds if they catch fire, and won’t spread the fire by dripping.

Without Built-In Control—Black Anodized Aluminum


Open Radiant Heater without Built-In Control (IP54)	Open Radiant Heater without Built-In Control (IP20)

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

Open Radiant Heater—Open heaters take up less space than enclosed heaters, but they get hotter, so they need to be further from other parts. These heaters have a chimney shape to direct heat upward.

Radiant Heating—Radiant heaters warm the air around the heater—use them for localized heat near batteries and other parts that don’t work well in the cold.

IP54 Enclosure Rating— An IP54 rating means heaters are protected against dust and water splashing in all directions.

IP20 Enclosure Rating—An IP20 rating means fingers can’t accidentally touch the circuits inside and get shocked.

UL 94 V-0—Heaters that meet UL 94 V-0 self-extinguish within 10 seconds if they catch fire, and won’t spread the fire by dripping.

Remote-Sensing Enclosure Space Heaters

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 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.

With Adjustable Thermostat

Heaters with thermostats turn on when the enclosure gets colder than the temperature you set.
