The ACR3 provides a passive means to automatically exchange probes without the need for requalification.


ACR3 uses Renishaw's unique autojoint connector to attach probes and extensions to the PH10M PLUS and PH10MQ PLUS motorised indexing heads. It can support a range of sensors from Renishaw and other metrology suppliers.

Although the ACR3 is a four port unit, two can be linked together so that eight different probes or extensions can be stored in the rack - sufficient for any measurement task.

A passive mechanism locks and unlocks the autojoint for secure and fully automatic sensor changes. The motion of the CMM is used to drive the change process, meaning that no additional motors or control are required.

The ACR3 is part of Renishaw's MRS modular rack system, meaning that an ACR3 unit can be combined with an FCR25 module change rack for SP25M scanning probe, or with SCP600 stylus change ports for the SP600M scanning probe.
