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

Under 2 ½” long, these tiny heaters fit in tight spaces, such as security camera enclosures. For localized heat in a large enclosure, place them near batteries and other parts that don’t work well in the cold.

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.
