Self-Latching Thanks to Chamfered Pin

Hanser’s indexing plunger selection is extremely diverse. And yet the standard parts experts continue to find new functional niches to fill: indexing plungers with chamfered pins.
They are nearly universal elements that can be found anywhere that latching, locking and securing is required: indexing plungers. Despite the diverse range of types and dimensions, they previously all had one thing in common: The latching process typically makes use of a cylindrical hole that is aligned with the plunger pin, allowing the pin to engage without difficulty. For example, when a carriage travels past a latching hole.
But there are also cases in which only an edge or a groove must suffice for latching, and it may not even be precisely positioned relative to the plunger pin. For such situations, Hanser has now developed a new type of indexing plunger that can independently latch into edges and grooves. This is made possible by a chamfered plunger pin. When the chamfered pin encounters a raised latching geometry, it retracts and then springs back out again once it reaches the latching point.
