MIL Environmental Construction: Unlisted Model 1820 can be furnished with a special sealed snaps switch for protection against high huidity, fungus and / or military applications. Similar to Model 1823 except dead band is slightly greater and some lower setpoints may not be possible. To order, add suffix MIL.
Example: 1820-2-MIL.
No. A-389 Mounting Bracket is 16 ga, steel, zinc plated and dichromate dipped for corrosion resistance. Provides rugged, permanent mounting and speeds installation.
