5-port autojoint rack bundle provides automated changing and covered storage for tactile probes, laser scanners, extension bars and other sensor accessories, without the need to requalify after exchange.  The rack uses a passive system, driven by the motion of the CMM and without additional motors or cables, to lock and unlock the probe head autojoint when changing components. TSR is part of a modular rack system which includes stylus storage racks (SSR), scanning module storage racks (MSR) and a range of different length rack support rails (RSR).  The image shows a 5-port autojoint rack (TSR-5) and SSR-3 (right).  The SSR-3 is not included in this bundle.
