This question is entirely justified, because unified wire colours would simplify everything. Not only the manufacturer&#8217;s different cable versions but also the documentation and installation at the customer&#8217;s. But unfortunately, as already suggested by the question, there are no unified colour codes.<\/p>\n<p>Every manufacturer follows his own philosophy, driven last but not least by his customers and suppliers. A preferred version (white\/black\/red) can only be detected to some extent with a few manufacturers on the American market. Thus, the only thing to be explained here is which &#8220;philosophy&#8221; WIKA&#8217;s electronic pressure department is following. Until a few years ago, WIKA always used to offer the following colour code: brown (S+), green (U+), white (0V). These wire colours were derived from DIN 47100, which was valid until the 90s.<\/p>\n<p>However, this standard is no longer valid. This is why for some time we have been adhering to a new unified colour code, which, by the way, is used by almost all manufacturers of inductive proximity switches and is offered nowadays as a standard by many manufacturers of adapter cables: brown (U+), blue (0V), black (S+).<\/p>\n<p>These colours have been adopted in 2007 by WIKA&#8217;s <a href=\"https:\/\/www.wika.com\/en-en\/a_10.WIKA\" target=\"_blank\" rel=\"noopener external\">Pressure transmitter A-10<\/a> for general industrial applications and recently also used by the special pressure sensor for medical gases <a href=\"https:\/\/www.wika.com\/en-en\/mg_1.WIKA\" target=\"_blank\" rel=\"noopener external\">MG-1<\/a>, thus being introduced stepwise into the product range.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Why are there no unified colour codes for cable wires of the pressure sensors?
