New optical sensors detect bumpy or shiny objects

Where a sensing application concerns the challenges of shiny, irregular, reflective or ultra-black objects (such as car body parts or wafers with anti-reflective coatings), the issues of poor accuracy and reliability become more consequential. These challenges frequently occur in the automotive and semiconductor industries, where the ‘time is money’ mantra is high on the ‘wish-list’ of system engineers and specifiers.

Their expertise in creating a proven portfolio of sensors and systems established over many industry sectors, means sensing and instrumentation specialists Baumer can continuously develop innovative, problem-solving sensors. An exceptional example of this is their new OT300 and OT500 optical sensors which deliver a wide detection range thanks to a line or spot beam ToF measurement, which, independent of the angle of installation, will reliably detect objects even with a ‘demanding or irregular’ surface.

They are developed to reliably detect objects within a significant sensing distance ranging up to 2.6m for the OT500 sensor and up to 1.8m for the more compact OT300, which is excellent for systems where space is minimal. The benefits of a compact design are supported by 3D CAD data with an integrated beam path aligned to the mounting holes with a component tolerance compensation (qTarget), and convenient teaching via qTeach and the standardised IO-Link interface with Smart Sensor Profile (DMSS).

Combining all these features allows users to accomplish intuitive parameterisation using the Baumer Sensor Suite software to enhance process transparency, thanks to easy access to secondary sensor data.
