The Thinswitch ® Limit Switch is specially designed to verify ejector plate return before permitting the mold to close in injection molding machines. Thin enough to fit inside the ejector housing, it can also be used for core slides, or any place space is limited. The Thinswitch Limit Switch has been tested for reliability in more than 10 million cycles without failure. Two switches can be used in series for larger molds to ensure the ejector plate returns, preventing costly mold damage. The Thinswitch Limit Switch is designed for use in very low power mold protection control circuits. It is not intended to switch heavy loads in power applications. • Prevents costly damage by ensuring the ejector assembly is fully returned • Adjustable operating point allows actuation between .187" and .250" from the base • 3 ⁄ 16 " thick design fits snugly behind the ejector plate in the space provided by the rest buttons • Included mounting hardware installs the Thinswitch Limit Switch easily • Stripped and tinned 6 ft. wire leads make the switch ready to install without modification • 175°F (79.4°C) standard temperature rating enables use for most molding applications • 250°F (121°C) high temperature unit is available for higher temperature needs • Quality tested over 10 million cycles to provide long, dependable service • Linear adjustment set screw can be set within .005 to .0025 • Premature spring and switch failure may result by adjusting the operating point more than .020" (.5mm) before the end of the ejector plate stroke • In stock to provide same-day delivery
