J.W. Winco Inc. offers GN 612.3 stainless steel, square, weldable, cam-action, indexing plungers. These RoHS compliant cam-action indexing plungers are best utilized when the pin needs to be retracted. When the lever arm is rotated 180°, the pin retracts into the indexing plunger housing. Grooves exist so the plunger pin can be held in both the non-retracted and retracted positions.
The square body can therefore be welded in any required position. In order to prevent a change in the spring load by the transferred heat of welding, spot welding the plunger body is recommended. The plastic ribbed sleeve, with maximum heat resistance of 110° C (230° F), offers an aesthetically pleasing and comfortable finger grip.
The housing, plunger pin, and spring are all stainless steel, while the optional and non-removable plastic sleeve is matte black technopolymer plastic.
