Sendix Encoders for All-round Safety [Mar 2012]

When choosing the right encoder for functional safety, ‘togetherness‘ is the secret, since safety is achieved via the intelligent combination of encoder, controller and actuator.  Sendix SSI/BiSS absolute encoders with additional Sin/Cos output and Sendix incremental encoders in Sin/Cos version are now available with SIL3 / PLe certification, which means that they play a key role amongst the components of a safe plant. 
The Sendix SIL absolute encoders obtain safe information about the absolute position; here the controller counts the incremental pulses and compares the result with the absolute position, which has also been provided by the same encoder. However in contrast, in the case of the Sendix SIL incremental encoders, the controller monitors the validity of the analogue, 90° phase-shifted sine/cosine signals with the help of the function sin²+cos² = 1. In addition, Sendix SIL-certified incremental and absolute encoders ensure a safe mechanical connection in the application. Here suitably dimensioned sturdy fixing elements guarantee 100 per cent reliability.   
Yet, for Kübler Sendix SIL encoders, safety goes much further. They feature a rugged, reliable interface and an ability to withstand high mechanical as well as electrical loads, thanks to extra strong bearings in the Safety Lock™ Design. The result is a very high degree of accuracy and a long service life. With their high IP67 level of protection and their magnetic insensitivity – thanks to optical scanning – the Sendix SIL encoders offer “All-round Safety”. 
With regard to the requirements of the Machinery Directive 2006/42/EC the MTTFd values for the most important standard encoders from Kübler are also provided.
This thus enables the user to carry out his own calculations according to DIN EN 61800-5-2 and DIN EN ISO 13849.  Contact :Kuebler Automation India Pvt.
