LINEAR MOTION
DAX linear encoders precisely determine the absolute position of pistons in hydraulic cylinders, as well as reliably monitoring linear motion in many common industrial machines. The SICK DAX linear encoders have been designed with a flexible product concept to make specification quick and easy for both new and existing users, using a unique online configuration tool with options for additional customisation. They therefore offer a timesaving way for cylinder manufacturers, OEMS and end-users to access a reliable source of supply. The DAX encoder family has industry- appropriate measuring ranges for countless applications as diverse as packaging machines, wind, hydro and solar plants, wood processing machinery, or medical technology. The encoders offer space-saving benefits for new machinery, as well as backwards compatibility with existing installations, and can be customised to work with all common magnet types.

DEVELOPMENT MILESTONE “The DAX encoder represents an important milestone in the development of SICK’s encoder portfolio,” explains Darren Pratt, SICK UK’s market product manager for Measurement and Instrumentation. “The encoders open up the availability of our

ICK has expanded its proven, non- contact magnetostrictive linear encoder portfolio with the launch of a versatile product family for wide- ranging industrial applications. The
NON-CONTACT LINEAR ENCODERS DESIGNED AROUND FLEXIBLE PRODUCT PLATFORM
magnetostrictive technology to industrial users for the first time. “In just a few steps, SICK’s Online Configurator guides the user through the specification process to generate a part number and create an online order. Thanks to the platform concept of the DAX, application- specific versions can be generated quickly. There is also the flexibility of further customisation for new machine designs, or to enable adaptation to existing machines, including where proprietary magnets are already in situ.” The DAX is being launched with three housing designs: one for integration into industrial hydraulic cylinders; a low-profile type with block magnets for mounting in tight installation situations; and a version with an integrated slider that guides the position magnet, easing the requirements on alignment during mounting.
Integration into existing or new machinery is straightforward using standard mechanical interfaces. For electrical installation, the DAX product family offers a CANopen as well as an analogue output for either 0-10 VDC or 4-20 mA.
DIAGNOSTICS AND OPERATING PROTECTION
Via the CANopen variant, operators have access to diagnostic capabilities to monitor both sensor parameters and environmental conditions, including the magnet signal, temperature, piston cycles/travel distance, power supply and operating hours. Diagnostics can also output speed and time profiles to monitor for changes in machine performance over time. In addition, the DAX encoders offer significant protection to ensure machine reliability in conditions where the power supply is vulnerable to fluctuations. The DAX offers
