Air rest button 3/16" CL-213-ARB

Air Rest Buttons allow using pneumatic position control to detect proper workpiece loading in a machining fixture. These modular units consist of a threaded body installed in a fixture, which holds a precision floating plunger. This plunger has a reamed hole, available in a choice of three diameters, that accepts any height of our standard press-fit-type Rest Buttons.

 

Proper placement of a workpiece on the Air Rest Button assembly causes the plunger to fully retract into the body. This seals off air flow, which increases the overall pressure of the system (30 psi maximum air pressure). This pressure value can be read using an analog or digital pressure sensor which can then be tied into a PLC or control system. Made in USA.  U.S. Patent No. US20190232446A1.
