Some of its features are:

  • Miniature size
  • Simple torque adjustment
  • Reliable design
  • Easy maintenance and repair
  • Low cost

Operational description:

When the power is applied to an R7 rotating paddle switch, a motor powers a revolving shaft to which a paddle is mounted.

When the material level inside the container reaches the revolving paddle, the paddle rotation is halted and the motor itself starts rotating around the shaft and activates an isolated SPDT micro switch. This removes power from the motor so that it stops rotating and an alarm signal is provided.

When the material level falls below the paddle, the motor resets and the micro switch restores the revolving action.

The R7 series miniature rotating paddle switches offer a number of variants to suit different application requirements. They can be used indoors or outdoors. The heat resistive type rotating paddle switch can be used to a temperature of 120 degree C.

The R7 series miniature rotating paddle sensors are available in Australia and New Zealand from Bestech Australia.
