Coordinate measurement probe body

A configuration for a coordinate measuring probe body having a relatively larger length dimension along the direction of a probe body axis and a relatively shorter cross-section dimension along a direction transverse to the probe body axis, the coordinate measuring probe body comprising:

• a rigid probe body structure comprising an upper mounting portion, an axial extension portion that extends along the direction of the probe body axis, and a compliant element mounting frame;
• a stylus suspension portion comprising:
• a moving element that couples to a stylus, and a configuration of compliant elements arranged to suspend the moving element from the compliant element mounting frame;
• a displacement sensing configuration arranged to sense displacement of the moving element relative to at least one of the compliant element mounting frame and the rigid probe body structure, the displacement sensing configuration comprising at least one displacement sensor that outputs a respective displacement signal;
• and
• a circuit board assembly comprising at least first, second, and third component mounting portions that are approximately planar portions and that extend along the direction of the probe body axis;
• wherein the configuration of compliant elements arranged to suspend the moving element from the compliant element mounting frame are attached to an attachment portion of the compliant element mounting frame that is distally located relative to a distal end of the circuit board assembly;
• and
• wherein the at least first, second, and third component mounting portions of the circuit board assembly are arranged around the axial extension portion of the rigid probe body structure and between the upper mounting portion and the attachment portion of the compliant element mounting frame.
