IDEACOD, the leader of the rotary sensor, offers also solutions with linear sensor. The sensor with cable does not need precise linear guidance. It is especially adapted to severe industrial environment : iron and steel industry, metallurgy, industry of wood (sawmills, joineries), etc... Principle of operation : a cable of measurement out of stainless steel, of great flexibility coated with a film polyamide, is rolled up and been held on a drum of precision. With the cable of measurement is associate interdependent of the drum, an optical encoder, of technology incremental, absolute, analogical or potentiometric..
