SMARTLOCK ®

SLIDE RETAINER AND LIMIT SWITCH

GENERAL DESCRIPTION
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 ejection while
the slide SPDT switch is simultaneously actuated. The SMARTLOCK slide retainer
®
and limit switch has been tested for reliability in over 10 million cycles without failure.
Two or more switches may be used for larger molds, or molds with multiple slides.
OPERATION
Installed in the slide, the plunger moves into a recess 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.

FEATURES AND BENEFITS
• Over 10 million cycle life provides long dependable service.
• 25 pound holding force: adjustable for optimum operation.
• 175°F (79.4°C) standard temperature rating allows
SPECIFICATIONS installation into most molding applications.
