anasonic has been a world leader in the design andmanufacture of small, compact photoelectric sensors for use in factory automation and industrial machine control for over 15 years. Now the latest technologies in electronics and product packaging have resulted in the introduction of the EX-Z Series of Ultra Miniature photoelectric sensors offering a reduction in packaging size of up to 50 per cent on previous generation products. An innovator of product miniaturisatio n, Panasonic is a world leader in the area of optics with expertise gained fromAV flat screen technology and award-winning Lumix camera design. This knowledge and know-how is seamlessly transferred to a portfolio of state-of-the-art factory automation products including an

The high performance characteristics of the EX-Z series are aided by the integration of a powerful LED (peak wavelength 650nm, modulated) into the transmitter element of the sensor. This together with the small diameter
transmission port, results in an extremely concentrated beam source that is normally only associated with laser- based technology.
A traditional through-beamsensing solution for pin presence on an LED or an Integrated Circuit duringmanufacture would typically be solved with fibre optic- based sensing technology, where the compact fibre sensor optics aremounted separately fromthe amplifier as space is normally at a premium. However, the technology requires adjustment during installation and commissionin g and is also liable to possible inadvertent operator intervention during themachine’s operation. The EX-Z Series eliminates such possibilities as there is no adjustment required and due to their compact nature they can easily be embedded into the structure of themachine,minimising operator interv

The size and manufacturing process involved in the production of the EX-Z Series ensures highly reliable operation which is ideal for the laboratory automation industry where such
performance is demanded. In addition to the IP67 protection rating of the sensors there are additional models available with high flex cables that are ideally suited to repeated movement in
machines where linear and robotic stages are used. Additionally these features are equally applicable to the areas of electronic manufacture and assembly where the industry demands fast, reliable and accurate sensing. With the trend of electronic components continually reducing in size it makes sense that the products used to create them are of the same technology and size.
The EX-Z Series sensor offers a wide range of options fo r thru-beam sensin g with two distinct packages offering front and side sensing meaning a flexible choice on mounting options. In addition, three sensing ranges, 50mm, 200mm and 500mm ensure accurate and reliable detection in numerous applications where accuracy and flexibility can be traded off against each other. The already mentioned standard and high flex cable solutions, together with a choice of PNP or NPN transistor outputs ensure that the sensors are designed fo r a global market which is synonymous with Panasonic and its vision to continue to drive the boundaries of innovation in the field of automation.
