J.W. Winco, Inc. now offers series GN 608.6 Metric Size Indexing Plungers with Rest Position, Plate Mount, Lock-out Type.
These RoHS compliant indexing plungers are used in applications which require surface mounting, and where the plunger needs to stay in its retracted position. To achieve this, the knob is rotated 90° after being retracted. The head of the plunger body is provided with a suitable notch in opposite positions so as to prevent the plunger from accidentally slipping back into its forward position.
The plunger pins are made of chemically nickel-plated stainless steel, and the mounting plate is also of stainless steel. The knob is matte black glass fiber reinforced nylon plastic, not removable.
