Two 10-second time delays add important benefits to the package. The first delay prevents nuisance alarms. The second delay accommodates an alarm to normal condition after the under speed status has been corrected.

This switch is housed in a gasketed weather-tight polyammide/fiberglass enclosure (allowing exposure to harsh environments), or a cast aluminum NEMA 9 enclosure for explosion-proof applications.

The unit is ideally suited for a wide variety of industrial applications where the need to monitor for under speed or slippage conditions exist. It may be used on conveyor belts, bucket elevators and other types of rotating equipment.
