Helping to prevent accidental mold close in injection molding applications, a Smartflow Thinswitch is tied to the injection molding machine control. The liquid-resistant limit switch is also designed to verify ejector plate return in areas where occasional water or oil spray is present. The company reports that the Thinswitch has been tested for reliability over 10 million cycles without failure, and two switches can be used in series for larger molds to ensure the ejector plate return, preventing costly mold damage.
With a standard temperature rating of 175Â°F and a high-temperature unit rated at 250Â°F, the 3?16-inch thick design fits snugly behind the ejector plate between the rest buttons. The limit switch is designed for use in very low power mold protection control circuits and is not intended to switch heavy loads in power applications.
