A limit switch box is mounted on and coupled to the actuator in order to operate position-indicating lights on control panels, to control other equipment such as pumps, compressors and mixers, to sequence other valves, or for feedback and PLC position confirmation. Two single-pole, double throw (SPDT) switches are mounted in one enclosure and are activated by individual, adjustable cams.
The cams are connected to the cam shaft, which is direct coupled to the actuator shaft. Switches can be set to be activated in fully open or closed positions, or in any position in the quadrant of the actuator’s operation.
The limit switch box is available in Type 4X and Type 7 enclosures, and switches can be supplied in mechanical or proximity models.
The electrical rating of the standard mechanical switches is 15 amps at 250 VAC, which qualifies them for the following voltages: 12 and 24 VDC, 12, 24 and 115 VAC.
Ideal Applications Include: Chemical Processing, Water & Wastewater, Landfills, Irrigation, Food Processing, Mining
