Rotary inner shaft with lock

TAPP series

Magnetically-coupled triple axis transfer arm, providing linear and rotary motion with a unique sample gripping mechanism allowing samples to be locked onto and off the probe. Linear and rotary motion of the sample is achieved via a single actuator with stroke length from 304mm to 1219mm. Unique lock/unlock mechanism then activates an independent shaft to provide gripper activation.

Show me more key features

The Triple Axis PowerProbe (TAPP) has two concentric output shafts providing two independent axes of motion. Linear and rotary motion of the outer shaft is provided through a high power magnetic coupling, driven by the thimble.

Compared with conventional devices the Triple Axis Power Probe provides more than 10 times the thrust and 4 times the torque with exceptional axial stiffness.

In addition to linear and rotary motion the thimble incorporates a unique secondary linear motion that can be used to lock/unlock samples held by a gripping end-effector.

This PowerProbe variant is ideally suited to system designers who need linear and rotary motion with an independent end-effector mechanism. When ordered with an end-effector the Triple Axis Power Probe provides the ultimate in secure sample transfer.

Standard End-effectors

Two standard end-effectors are offered to grip and safely transfer industry-standard surface analysis flag and puck sample holders.
