This allows control processes to be implemented in various electrical or electronic systems, for example for volume control in multimedia devices.<\/p>\n<p>A\u00a0<a href=\"https:\/\/alders.de\/en\/products\/potentiometer\/\">rotary potentiometer<\/a>\u00a0consists of three contacts, a carrier, and a circular resistor material. The two outer contacts are fixed and both are connected to the resistor. The third contact is movable and is known as a slider. In conventional designs, this can be rotated by up to 300 degrees via a rotary axis. By shifting the slider, the integrated resistance becomes either larger or smaller. This is how, for example, the voltages in a circuit can be variably controlled or exotic resistances can be generated.<\/p>\n<p>With rotary potentiometers, a distinction is made between linear and logarithmic variants: a linear rotary potentiometer changes the resistance used analogously to the set angle of rotation. With a logarithmic rotary potentiometer, on the other hand, the value of the resistance initially changes less and increases proportionally with increasing rotary motion.[\/vc_column_text][\/vc_column_inner][\/vc_row_inner][\/vc_column][\/vc_row]<\/p>\n<\/div>","protected":false},"featured_media":0,"template":"","class_list":["post-292459","glossary","type-glossary","status-publish","hentry"],"acf":[],"_links":{"self":[{"href":"https:\/\/alders-v2.p3group.de\/en\/wp-json\/wp\/v2\/glossary\/292459","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/alders-v2.p3group.de\/en\/wp-json\/wp\/v2\/glossary"}],"about":[{"href":"https:\/\/alders-v2.p3group.de\/en\/wp-json\/wp\/v2\/types\/glossary"}],"version-history":[{"count":1,"href":"https:\/\/alders-v2.p3group.de\/en\/wp-json\/wp\/v2\/glossary\/292459\/revisions"}],"predecessor-version":[{"id":292460,"href":"https:\/\/alders-v2.p3group.de\/en\/wp-json\/wp\/v2\/glossary\/292459\/revisions\/292460"}],"wp:attachment":[{"href":"https:\/\/alders-v2.p3group.de\/en\/wp-json\/wp\/v2\/media?parent=292459"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
