Compare FrontSense optical and radio CNC probes for retrofit and replacement projects involving common Renishaw OMP40-2, OMP60 and RMP series installations.
Matching form factors and practical retrofit options
Options for legacy and modulated optical transmission
Receivers, interfaces and measurement software available
Application review before shipment to reduce compatibility risk
A reliable probe replacement requires more than matching the outside diameter. Transmission method, receiver protocol, operating range, shank, stylus length, machine control and probing macros all affect compatibility.
Send us the existing probe and receiver model, machine make, CNC control and photos of the installation. Our engineers will recommend a compatible FrontSense configuration or explain which existing components should remain in place.
Compact optical workpiece probe for machining centers.
Optical probe with longer transmission range.
Compact radio probe for line-of-sight-independent operation.
OSMP40-2 supports legacy and modulated optical environments.
FrontSense is an independent manufacturer. We do not claim identical hardware, identical firmware, or guaranteed drop-in fit on every spindle. Compatibility is confirmed case by case against your receiver, stylus stack and macros.
This table maps typical applications to FrontSense models. It is not a claim of identical parts. Exact interchange depends on receiver, interface, stylus and macros, so send a nameplate photo of your current probe and receiver before ordering.
| Typical application | FrontSense model | Transmission | Repeatability (FrontSense catalog) | Typical use |
|---|---|---|---|---|
| Compact optical probe for small/medium VMCs (OMP40-2-class applications) | OMP40-2 | Optical, 360° | ±1 μm | Small and medium machining centers |

We do not publish side-by-side numeric claims against Renishaw catalog figures. Ask for a model-match sheet for your machines. See also the OMP40-2 selection guide.
Compatibility depends on the probe, receiver, transmission protocol, shank and macros. We verify these details before describing a configuration as drop-in. FrontSense products are independent alternatives for comparable applications, not identical copies.
In some installations, yes. Send the receiver model and revision plus machine details so our engineers can confirm. Other installations require a matched FrontSense receiver. Do not assume every probe/receiver combination works.
Provide the current probe and receiver models, machine make and model, CNC control, spindle taper, stylus size and installation photos.
FrontSense supplies measuring macros for FANUC, Siemens and Mitsubishi. Confirm your control software version and any custom macros at quote.
See OMP400, our high-accuracy probe using strain-gauge sensing. It is an independent FrontSense design. We confirm the accuracy figures for your application at quote.
