The DS9093RB is formed with a slight dome to improve the gripping force exerted onto the pre-punched material. The domed side of the washer should face the flange of the iButton, the flat side should face the material. iButton is a registered trademark of Maxim Integrated Products, Inc. 1 of 2 DS9093RA/RB REVISION HISTORY REVISION DATE 8/09 DESCRIPTION Added an Ordering Information table. 2 of 2 PAGES CHANGED 1
