In-Mold Sensors
In-mold sensors help prevent accidental mold close in injection molds by verifying the position of mold components such as ejector plates, slides, and cores.
About In-Mold Sensors
Thinswitch, Smartlock, and Versaswitch are the industry standards for injection mold tool protection.
Mold-builders around the world rely on Thinswitch for ejector plate return confirmation.
Molds with slides are particularly vulnerable to mold crash due to their complexity. Smartlock switches include a slide detent and switching function.
Confirmation of mold component position before mold closes helps prevent costly tool damage and downtime for repairs.

Thinswitch and Smartlock switches have been tested for reliability over 10 million cycles without failure.
No. Thinswitches are designed to be the same height as 3/16″ rest buttons. For rest buttons with 3mm or 4mm height, use a Global Thinswitch.
Thinswitch, Versaswitch, and Smartlock have SPDT switching action with Normally Open, Normally Closed, and Common wire connections.
Global Thinswitch has SPST action with two open contacts that make connection on actuation.
