Features & Benefits
-
A. Enclosure
The compact low profile weatherproof VSM is UL certified NEMA Type 4, 4x and IP66/67. Aluminum base and cover for exceptional corrosion, wear and impact resistance.
-
B. High Visibility Position Indicator
Visual open and closed indication is provided with an impact resistant dome style indicator. Inverting the open and closed visual output is easily done by rotating the indicator dome 90 degrees.
