RENISHAW OMP40-2 Digital Optical Transmission Probe for Machine-tools

Buy online your RENISHAW OMP40-2 Digital Optical Transmission Probe for Machine-tools reference OMP40-2 from our US e-store Cnc-shopping USA, specialist in CNC machine-tools spare parts.

The RENISHAW optical touch-trigger probe is used for workpiece setup and in-process measurement on machining centers. This compact unit communicates by digital optical transmission and serves as a reliable replacement unit or refurbished spare part for shops maintaining Renishaw optical probing systems on small to medium machines and high speed spindles with small tapers.

This model uses a proven kinematic mechanism that delivers stable triggering and consistent reseat over long service intervals. The modulated optical link provides strong resistance to ambient light and coolant reflections, helping prevent false triggers on the production floor. A full 360 degree transmission envelope supports line-of-sight reception around the spindle, which is helpful near tool changers and compact enclosures.

Commonly deployed on small and medium machining centers, and on an increasing number of high speed machines with small HSK attachments, the unit is selected for tight spindle spaces where an ultra-compact body is required. Typical repeatability is 1 micron at 2 sigma when correctly installed and calibrated. It works with RENISHAW optical receivers, which simplifies upgrades and field replacements on existing optical installations.

For maintenance teams, the probe can be a direct swap when the same shank and stylus type are retained, limiting requalification time. Shops often keep one in spare inventory to cover unexpected probe failures or intermittent triggers caused by collision, contamination or battery end-of-life, which helps reduce machine downtime.

In industrial service this probe is used to establish datums, verify features, and run in-cycle checks that support reliable machining results. As a field replacement it helps restore probing cycles after crashes or wear related drift, and as a stocked spare it supports preventive planning on multi-machine sites that share the same optical receiver architecture.

Each refurbished unit is inspected and verified by skilled engineers on appropriate CNC probing test benches or simulators. Trigger repeatability and optical transmission are checked, then the unit is packed for industrial shipping. A functional warranty is provided by Cnc-shopping USA to support maintenance operations.

For urgent breakdowns this model can serve as an emergency spare part to reduce unexpected downtime. Cnc-shopping USA supports sourcing for hard-to-find and obsolete parts, and repair or exchange services may be available to keep legacy Renishaw optical probing systems in operation.

Frequently asked questions about OMP40-2 :

Will this RENISHAW OMP40-2 probe work with my existing RENISHAW optical receiver?
Yes, it is designed for use with RENISHAW optical receivers. For best results, confirm the receiver model and ensure correct optical alignment and configuration during commissioning.

Is the compact format suitable for high speed spindles with small HSK tapers ?
The small body is intended for tight spindle envelopes and is widely used on high speed machines with small tapers and HSK style attachments, provided the correct shank and balance practices are observed.

What repeatability can I expect in normal shop conditions ?
When properly installed, calibrated and maintained, typical repeatability is around 1 micron at 2 sigma. Environmental cleanliness, stylus condition and machine setup influence the achieved results.

Can I reuse my existing probe shank and stylus ?
In many replacements the existing shank and stylus can be reused if they match the probe interface and are in good condition. Inspect wear items and verify runout before returning the machine to production.
