Sick UK has upgraded its range of 30mm ultrasonic sensors.
The newest version of the UM30-2 series is said to offer additional performance and usability, meeting a wider range of presence, distance and safety sensing requirements in the packaging industry for applications such as bin and pallet stacking, and warehousing.
The improved UM30-2 series includes a filter setting adjustment that enables the user to change between a high security mode, which protects against false signal switching but has a slower update, and a fast response mode for highly dynamic applications, which do not require such a high level of false switching security. This is claimed to give the customer the facility to fine-tune the performance of the sensor enabling the UM30-2 to be used in more diverse application areas.
Another new feature is the Multiplex switching mode that enables up to 10 UM30-2 sensors to be connected to measure large areas, with integrated phase switching to prevent mutual interference and false switching. Sick claims it can cope with targets of different colours or even transparent materials, water and film with no difficulty.
Digital or analogue output variants of the UM30-2 are available, with the analogue variants capable of producing 4-20mA or 0-10V at their output. Selection of analogue output type is either automatic – the sensor detects the impedance of the load at power up, or manual – via the intuitive menu structure.
At between 84mm and 105mm long, the new range of sensors are 25% shorter than the original. However, the 30mm to 8000mm operating range is claimed to one of the widest available for this class of sensor. Pricing for the updated sensors remains unchanged.
