Spring, Pneumatic Push and Vacuum Retract Probes

Contact gauge probes often provide the most cost effective solution for a wide range of measuring and positioning applications.

In a conventional pencil probe the tip is pushed out using an internal spring. When installed in a fixture it is frequently required to design a mechanism to bring the probe into contact with the part being measured.

A pneumatic probe (either pneumatic push or vacuum retract) allows the number of parts in the fixture to be reduced resulting in improved reliability and reduced fixture cost. It also allows for fast automatic loading of the part into the gauge as the probe tip can be in the fully ‘retract position’ when this is occurring. Probes such as the AX/5/1 have a mechanical movement of 10 mm with a calibrated range of ±1 mm at the beginning of the movement.
