The AL9 series rotary potentiometers in 13 mm housing are designed for applications which requiring a miniaturized, economical and accurate multiturn potentiometer for moderate actuations. Miniaturized and economical manual adjuster Precise 1turn rotary potentiometer With axial or radial connections Versions for direct PCB mounting The miniaturized 1turn rotary potentiometers AL9 are preferably used as manual setpoint adjusters. The resistance element offers a lifespan of over 2, revolutions. Please note the quite identically (design) series AL1 (wirewound element 2 million) and AL11 (hybrid element 1 million), which were developed for applications with longer life characteristics. 1 VAC, 1min 1 5 VDC Mechanical Data, Environmental Conditions, Miscellaneous 3turn 5turn 1turn Mechanical angle of rotation Lifetime (9% el. eff. angle half sine) 2.)
