Renishaw Launches PH20 PLUS 5-Axis Touch-Trigger System with 300 mm Inspection Reach

Renishaw has introduced the PH20 PLUS 5-axis touch-trigger system for co-ordinate measuring machines (CMMs), a direct replacement for the established PH20 head that pushes inspection reach past the 300 mm mark.

With a 50 mm stylus, the PH20 PLUS head provides a maximum working length of up to 300 mm from the centre of the A-axis.

Longer probes, same measurement pedigree

The reach gain comes from a redesigned A-axis with a new kinematic mount that supports longer probe configurations. Based on the industry standard TP20 probe system, new PE20 modules feature a larger kinematic mount for direct interface with the PH20 PLUS head and are available in a range of lengths to suit different applications.

The PH20 PLUS builds on a proven platform. The original PH20 touch-trigger system, launched in 2010, utilises head motion technology developed for the REVO® 5-axis measurement system — technology that minimises the dynamic errors of a CMM at higher measurement speeds and drove substantial throughput gains for manufacturers globally.

"With PH20 PLUS, we've focused on extending capability which we think will appeal to both existing PH20 customers and those with measurement requirements which could previously not be met by the existing head," said Nathan Fielder, Product Manager at Renishaw.

Protecting the installed base

Renishaw has clearly thought about the upgrade path. The PH20 PLUS system has been designed as a direct replacement for the PH20 and maintains compatibility with the existing range of TP20 modules, which can be used via the PB20 adaptor. That lets customers keep their current hardware, established stylus configurations, and existing part programmes. The system can also be configured to match the effective working length of existing PH20 installations, simplifying replacement decisions.

Integration is equally straightforward: the system is fully compatible with Renishaw's UCC controller and integrates in the same way as the original head.

Automated module changing

A new modular rack system supports automatic and repeatable probe module changing, mounting to an MRS2 rail that can be installed on the CMM bed or directly onto the machine frame. The rack includes configurable change ports for TP20 modules, temperature-controlled ports for PE20 modules, and connector modules to distribute electrical power. A powered PCR20 rack provides a standalone option for holding multiple probe modules and accessories.

See it at IMTS

Visitors to IMTS 2026 can see the PH20 PLUS demonstrated on the booths of various CMM manufacturers, with Renishaw staff available at the Quality Assurance booths 134314 and 134524.
