Millimetre perfect from ifm electronic

Precise ToF distance sensor for demanding applications

Thanks to the innovative on-chip time-of-flight principle with PMD technology (photonic mixer device), the new OGD precision sensor from ifm electronic, offers all the capability of an extremely precise measurement system. The distance information can determine the presence of parts or their correct installation, e.g. if an O-ring has or has not been mounted. The excellent reflection resistance and background suppression, together with a high excess gain, enable reliable operation. The PMD technology of the OGD is vastly superior to conventional diffuse reflection laser sensors and the device is available with an extremely small light spot at a 300 mm range for the detection of very small parts. The switch point is easily set to the nearest millimetre via the three operating keys or alternatively via IO-Link, which also allows read-out of the current distance value.
