Air Rest Buttons utilize 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. Patent pending. Made in the USA.

Position sensing threaded rest button with a hex machined .005 to .01” over nominal height for finish grinding after installation. 

• Sensor contains .06 through hole allowing air to travel through and detect whether a part is loaded utilizing a sensor. 
•  The position sensing rest button also contains a #10-32 tapped hole on the shank for installation of a threaded nipple for easy air line installation.
•  Available in inch and metric, Made in the USA

This edge clamp is well suited for holding large castings and other tall workpieces in automation applications. 

• The pivoting jaw exerts clamping force forward and downward at the same time. The jaw has a replaceable serrated gripper made of hardened tool steel for high-production durability. 
• The slotted base provides adjustability and has a tapered top surface to prevent the clamp from moving. Fasten with two Socket-Head Cap Screws.

• Pneumatic Toggle Clamps are similar in design to standard hold-down toggle clamps, but they are operated by a double-acting air cylinder rather than manually. 
• The toggle linkage provides high holding capacity and insures positive mechanical locking even if air pressure fails.
