Bourns Sensors & Controls Product Line Introduces Model ECW Product Enhancement In line with our commitment to product excellence and continuous improvement, the Bourns Sensors & Controls Product Line is pleased to introduce a product enhancement to the Model ECW Rotary Contacting Encoder. The Model ECW contacting encoder offers two types of shaft diameters - metric and standard. As an improvement and poke-yoke in our assembly process and to prevent mixing of shaft sizes, a cross slot feature has been added to the metric "R style" shaft in order to easily identify the metric shaft version. This feature is cosmetic only and does not affect fit or function of the part. Form/appearance of the shaft will change from a single slot to a cross slot. Please contact a Mouser Technical Sales Representative for further assistance. 5-1012-55
