The RMP24 probe from Renishaw plc - wireless touch-trigger for tight CNC setups

The RMP24 probe sits small and self-assured on the machine table, its polished body catching the strip light while the spindle glides past with a quiet hum. In a crowded CNC cell, it feels like a tidy extra hand that never gets tired.

What the RMP24 does

The RMP24 from Renishaw is a compact wireless touch-trigger probe designed for workpiece inspection and job setup on CNC machining centers. It uses a strain-gauge sensing mechanism to deliver consistent triggering performance even on complex surfaces.

The probe is optimized for tight installations where a larger spindle probe would get in the way, with a 24 mm diameter body that helps free up machine envelope. It is part of Renishaw's broader family of radio-based probes for flexible in-process measurement in production.

How wireless probing helps

Instead of trailing cables or optical line-of-sight constraints, the RMP24 communicates over radio, so operators can load parts without worrying about blocking a receiver window. That matters in multi-pallet systems where fixtures and tombstones can create visual clutter around the spindle.

Inside the probe, strain gauges detect the touch event rather than simple mechanical switches, which reduces lobing errors and gives more repeatable results over many cycles. In practice, that means the same probing routine can be trusted on a Monday morning and a Friday night shift.

Signal coding and compatibility

Renishaw offers the RMP24 with its radio signal protocol designed to coexist with other probes and tool setters in the same machine environment. That allows factories to mix spindle-mounted inspection and table-mounted probes without wrestling with interference settings every week.

The probe works with Renishaw's radio interfaces and macro software, so engineers can drop standard probing cycles straight into their CNC programs. In many installations, that turns manual edge-finding with paper strips into automated routines that run after each tool change.

On the shop floor with engineers

Product manager Ben Davis describes the RMP24 as an answer to customers who "needed radio probing where space is at a premium" in compact machining centers. Walking through one of Renishaw's demo cells, he points to the probe sitting just clear of a vice, ready to touch off a batch of aluminum engine brackets.

Operators tend to notice the probe most when it saves a scrapped part: a quick in-process measurement flags a misloaded blank before the expensive finishing cuts start. That quiet intervention is the kind of practical win that keeps the device on the machine rather than in a drawer.

Metrology as a business pillar

Renishaw builds the RMP24 inside a broader metrology portfolio that includes spindle probes, tool setters and laser systems for machining centers. The company positions these products as part of a closed loop where measurement data tightens process control and reduces waste on the shop floor.

For investors, this metrology segment sits alongside analytical instruments and healthcare, forming the manufacturing technologies pillar of Renishaw's revenue mix. That combination of hardware and software has allowed the firm to occupy a precise niche in global precision engineering.

Stock context and listing

Renishaw shares (ISIN GB0007365546) are listed in London under the ticker RSW, giving UK and international investors access to the metrology story via the home exchange. All told, the performance of products like the RMP24 feeds into the long-term demand picture for high-value machining solutions.
