The DRS60 incremental shaft encoder, launched by SICK|STEGMANN, is the only incremental encoder in the world to feature an electronic adjustment of the once per revolution pulse (Plate 7).
Plate 7
The DRS60 incremental shaft encoder
Users and manufacturers of print registration equipment fitted to printing and packaging machinery must align the once per revolution pulse produced by the incremental encoder with a specific part of the machine cycle to ensure that the print registration system functions correctly. As the width of the pulse can be less than 1/100th of a degree, this can be a time-consuming exercise with conventional encoder designs where the encoder shaft must be manually moved to the position where the once per revolution pulse occurs prior to mounting.
The DRS60 has a button located under a cap on the rear of the encoder. When this button is pressed, the position where the zero-pulse occurs is instantly shifted to the current shaft position. Therefore, it is no longer necessary for the commissioning engineer to manually move the encoder shaft prior to mounting. The DRS60 is simply mounted and the button pressed.
With conventional encoder designs the time taken to align once per revolution pulse with the machine mechanics can be in excess of 20 to 30min. Owing to its unique electronic adjustment, alignment can be performed with the DRS60 in a matter of seconds.
The DRS60 is available in solid shaft and hollow shaft designs, with cable or connector exit and a choice of output circuits including RS422 (TTL) and push-pull (HTL). All feature the electronic adjustment of the once per revolution pulse and are available on very short delivery lead times.
