Bourns® Models 3547, 3548 & 3549 Precision Potentiometers Product Brochure Introduction In line with our commitment to provide continuous This new model family is built utilizing our improvement of our technologies and designs, classic wirewound and Hybritron® technologies Bourns® Sensors and Controls Division is pleased with several product enhancements, process to announce the long-awaited release of the new improvements and newly added options to provide Model 3547 3-Turn, 3548 5-Turn and 3549 10-Turn a more reliable product with superior performance. Precision Potentiometer family. Product Enhancements This model family will provide a higher-grade alternative to our legacy Models 3540, 3541, 3543 and 3545. Product enhancements of the new model family over the legacy product are: • The cover that houses the element and lid is heatstaked to provide a better dust seal. • The bushing is molded into the front lid rather than assembled to the housing with a metal strap. • The bearing surface between the rotor and the front cover has been improved to provide a longer wearing surface. • The bushing has been upgraded to a brass and bronze bearing surface for better wear characteristics under side load. • A tighter resistance tolerance on new resistive wire for better electrical performance. • A new bondable mandrel holds the resistive wire in place to provide uniform spacing and better electrical performance. • A newly designed contact spring provides increased rotational life. • Higher-grade plastics have been selected for a more robust package and better performance of internal mechanical assemblies. • The solder terminal thickness has been increased to provide a more robust terminal. • Higher-grade grease and lubricants have been selected for smooth rotational shaft feel and for low temperature operation. In addition to these enhancements, this new model family is RoHS compliant in accordance with Directive 2002/95/EC on the restriction of the use of certain hazardous substances (RoHS) in electrical and electronic equipment. Standard Options • Panel mount bushing or servo lid Outline dimensions and enhancements to • Single or dual gang performance are summarized in the adjoining • Wirewound or Hybritron® element specification sheets. For value-added product • ±0.25 to ±0.10 % independent linearity enhancements, please contact your local Bourns • Slotted or flatted shaft Sales Representative or one of our Field Application • Various shaft lengths Engineers. • Various shaft diameters • Anti-rotation pin • Optional bronze bushing and stainless steel shaft (for applications where side load is encountered) 3547 Cross Reference List Wirewound Old 3543S-1-102 3543S-1-202 3543S-1-502 3543S-1-103 New 3547S-1AA-102A 3547S-1AA-202A 3547S-1AA-502A 3547S-1AA-103A 3548 Cross Reference List Wirewound Old 3545S-1-102 3545S-1-202 3545S-1-502 3545S-1-103 New 3548S-1AA-102A 3548S-1AA-202A 3548S-1AA-502A 3548S-1AA-103A 3549 Cross Reference List Wirewound Old 3540S-1-201 3540S-1-501 3540S-1-102 3540S-1-202 3540S-1-502 3540S-1-103 3540S-1-203 3540S-1-503 3540S-1-104 New 3549S-1AA-201A 3549S-1AA-501A 3549S-1AA-102A 3549S-1AA-202A 3549S-1AA-502A 3549S-1AA-103A 3549S-1AA-203A 3549S-1AA-503A 3549S-1AA-104A Hybritron® Old 3541H-1-102 3541H-1-202 3541H-1-502 3541H-1-103 3541H-1-203 3541H-1-503 3541H-1-104 New 3549H-1AA-102A 3549H-1AA-202A 3549H-1AA-502A 3549H-1AA-103A 3549H-1AA-203A 3549H-1AA-503A 3549H-1AA-104A Model 3547 Electrical Characteristics1 Standard Resistance Range Total Resistance Tolerance Independent Linearity Independent Linearity (Maximum Practical) Effective Electrical Angle Absolute Minimum Resistance/End Voltage Noise/Output Smoothness Max.
