About OMP400

Strain gauge structureThe OMP400 is an ultra compact probe, ideally suited to small to medium machining centres. It combines the miniaturisation of the highly successful OMP40 probe with new advances in strain gauge technology, pioneered by Renishaw's high accuracy MP700 probe.

Strain gauges attached to the structure measure the smallest of stylus motions, allowing for a very sensitive system.

The innovative RENGAGE™ technology built into the OMP400 brings unrivalled performance in terms of 3D measurement. Use OMP400 with Renishaw OMV for advanced on-machine verification when machining contoured surfaces and complex shapes.

OMP400 features and benefits

  • RengagePatented RENGAGE™ technology brings unrivalled performance in terms of 3D measurement.
  • Increased stylus lengths can be supported without a significant decrease in probe performance
  • Compatible with all existing Renishaw optical receiver interfaces (modulated: OMI-2T, OMI-2C, OMI-2 and OSI/OMM-2; legacy: OMI)
  • The OMP400 sets new standards for reliability and, sealed to IPX8, OMP400 is designed to resist the harshest machine conditions

    Since the invention of the touch trigger probe by Sir David McMurtry in 1972, probing has become a vital component of automated production processes on machine tools. This simple mechanism, employing a kinematic location to retain a stylus in a highly repeatable manner, has formed the basis of many Renishaw probes for over 30 years. Renishaw kinematic touch trigger probes continue to serve the manufacturing industry well, remain the markets best selling probing products by far, and are the first choice of the majority of end users and machine tool builders alike. The level of measuring performance and reliability of these probes must not be understated.
