Ultrasonic sensor overcomes optical
problems
The ZWS miniature ultrasonic sensor is ideal for packaging applications such as clear film detection where traditional optical sensors sometimes experience problems.
For packaging applications such as clear film detection where traditional optical sensors sometimes experience problems, Balluff has introduced to the UK the ZWS miniature ultrasonic sensor The use of sound waves rather than light to detect object presence means that the sensor remains 100% reliable despite changes in product colour, texture or transparency

Micropulse magnetostrictive linear transducers from Balluff-MultiSwitch are now available with integrated Profibus-DP, and automatic baud rate detection by the transducer assures trouble-free startup
Although almost all products have good enough sound reflective qualities to reflect echoes for direct detection, the ZWS ultrasonic sensors have a novel "retroreflective" automatic teach in mode to ensure that problems associated with poor sound reflectors and echo loss due to awkward target shape and geometry are no longer an issue.
Packaged in a small 20 x 32 x 12mm housing which is externally identical to popular optical sensors, the ZWS uses pushbutton teach-in setup to ensure that direct replacement of troublesome optical sensors is hassle free and easy by using existing mounting holes and bracketry.
