Pneumatic Probe

Pneumatic probe is mainly used for functional test. It has similar construction to pneumatic cylinders, but the scale is
much smaller; the barrel of the probe, being the cylinder, and the plunger, being the piston. An ¡°O¡±  Ring, which is
mounted on a collar, seals airpressure in the probe; the collar can be regardedas a fixed part of the plunger design. Electrical
continuity or signal transfer between the tip of theprobe and the wire clip terminal at the base of the probe is attached
through a sliding metallic ring which guarantees a good electrical connection between the sliding plunger and the barrel.Unlike
conventional spring contact probes, pneumatic probes achieve their contact force through air pressure applied to
the probe, which is typically 6 bar.
