Renishaw Extends 5-Axis Touch-Trigger Reach with PH20 PLUS

Renishaw has introduced the PH20 PLUS 5-axis touch-trigger system for coordinate measuring machines, announced in September 2026 as a direct replacement for the established PH20 head. The headline improvement: over 50% more inspection reach.

Longer probes, deeper access

The core change is mechanical. A redesigned kinematic mount supports longer probe configurations, and the PH20 PLUS head delivers a maximum working length of up to 300 mm with a 50 mm stylus. That translates to an additional 107 mm of reach — meaningful for anyone who has fought to access features deep inside a part with the original head.

Upgrade path protects existing tooling

Renishaw is clearly courting its installed base. The PH20 PLUS system maintains compatibility with the existing range of TP20 modules, excluding the extended force module, and existing TP20 probe modules can be used via the PB20 adaptor. That keeps current hardware — and the part programmes built around it — in service.

"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.

Automation and integration

A new modular rack system supports automatic and repeatable probe module changing with the PH20 PLUS head, with the PCR20 rack providing a standalone solution for holding multiple probe modules and accessories. On the control side, the system is fully compatible with Renishaw's UCC controller and integrates in the same way as the original PH20 — a genuine drop-in replacement.

The PH20 PLUS system will be demonstrated at IMTS 2026.
