行程开关，限位开关Limit Switch SmartLock
SmartLock slide retainer and limit switch is designed for injection molders to provide switching plus slide retaining in one unique package.The SMARTLOCK locking function prevents premature slide movement during molded part ejection while the SPDT switch is simultaneously actuated. The SMARTLOCK slide retainer and limit switch has been tested for reliability over 10 million cycles without failure. Two or more switches may be used for larger molds, or molds with multiple slides. Increased safety and prevention of mold damage result when the SMARTLOCK slide retainer and limit switch is installed in a mold. A capture screw holds the pluger in place.
Features and Benefits
1)      New capture screw prevents plunger loss
2)      Over 10 million cycle life provides long dependable service
3)      27pounds holding force:adjustable for optimum operation
4)      175 degrees F (79.4degrees C)standard temperature rating allowe installtion into most molding applications
5)      250 degrees F (121degrees C)high temperature unit provides additional application flexibility
6)      Superior flush mount switch shielded from damage by mounting inside a protective milled pocket
7)      Stripped and tinned 6 ft.wire leads make the switch ready to install without modification
8)      Included mounting screws and wire clips help install the SMARTLOCK switch neatly and easily

Mode of Operation
Installed in the slide,the plunger moves into arecess in the locking plate of the switch assembly,which is installed in the mold plate.The switch actuator,located in the bottom of the recess,closes the normally open switch contacts when the plunger is seated in the locking plate recess,When the break away force is applied to the slide,the lock is released,and the switch returns to its normal state
