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

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

The RENISHAW OMP40-2 is a compact optical 3D touch-trigger probe used for on-machine part setting and in-process inspection on small to medium CNC machining centres. It communicates with installed RENISHAW optical receivers, providing reliable probing for datum setting, work offset definition and feature verification on the machine, including high-speed spindles with small HSK holders.

A robust kinematic trigger delivers 1 µm repeatability (2σ) under standard conditions, supporting precision workholding and repeatable offset capture. The ultra-compact body suits tight tool changer envelopes where clearance is limited, which is common on modern high-speed VMCs and compact horizontal platforms. The optical system provides a 360 degree transmission envelope with modulated signalling that resists bright enclosure lighting and reduces sensitivity to line-of-sight alignment.

Integration is straightforward on machines already equipped with RENISHAW optical interfaces, making this model a practical replacement unit when an existing probe has failed or become intermittent. The sealing concept is designed for coolant-rich environments, helping maintain stable operation where spray, mist and chip washdown can otherwise disrupt measurement.

For retrofit or maintenance, the OMP40-2 is commonly used to restore probing capability with minimal program changes. It is frequently selected by maintenance teams as a CNC replacement component on probe-ready machining centres where reliable part pick-up and in-cycle checks are required without extending cycle time.

Logistics Refurbished and tested unit supplied with a functional warranty, with fast dispatch depending on availability from our UK e-store.

In daily shop use this model supports reliable work offsets, quick part set-up and in-cycle checks that help detect drift before it becomes scrap. As a spare part it is often installed after crash events, liquid ingress or unstable triggering, allowing machines to return to service quickly with familiar probing routines.

Many sites hold an OMP40-2 in their industrial spare inventory to shorten stoppages. Keeping a tested unit on the shelf enables a swift swap during planned maintenance or an unexpected failure, while the removed probe can follow a controlled repair service or exchange service process.

Each refurbished unit is verified on appropriate CNC test benches or simulators by skilled engineers. Probes are packaged for industrial transport with protection for optics and metrology faces, and supplied with a functional warranty. Cnc-shopping UK provides secure shipping with worldwide shipping options and support from our technical team.

When a legacy probe becomes an obsolete part or sourcing is tight, this model is a dependable emergency spare to reduce downtime. Cnc-shopping UK can assist with repair, exchange and alternative sourcing so older CNC installations remain operational.

Frequently asked questions about OMP40-2:

Will it pair with the RENISHAW optical receiver already fitted on my machining centre?
Yes, it is designed to operate with commonly installed RENISHAW optical receivers. Check the receiver type and configuration on your machine for correct pairing and signal settings.

Is it suitable for high-speed spindles with compact HSK toolholders?
The compact format and 360 degree optical envelope suit small HSK tapers and tight ATC clearances often found on high-speed machines.

What repeatability should I expect in service?
The stated figure is 1 µm (2σ) under standard test conditions. Real-world results depend on spindle condition, macros, probing velocity and fixture stability.

Can it be used as a direct field replacement for a damaged unit?
In most cases it is a drop-in swap on RENISHAW-equipped machines. Verify mounting, receiver alignment and re-qualify probing cycles after installation.
