Ifm electronic manufactures compact pressure switch. The pressure switch/ sensors are distinguished with features like high pressure peak and aggressive media resistance. The pressure switch/ sensors are available with radial setting rings with a unit that allows optimum reading for quick and precise adjustment of set and reset point without system pressure being applied. These switches/ sensors are available with mechanical locking property that ensures no unauthorized manipulation. These pressure switches/ sensors are provided with two clearly visible leds as switching and operating status indication for required feedback. These robust pressure switch/ sensors are useful for all industrial and mobile applications with not only standard hydraulic and pneumatic applications but also up to 400 bar gas pressures or air conditioning and refrigerating technology applications. The pressure switch/ sensors come with stainless steel robust measuring cell for high long-term stability and wear-free operation over millions of pressure cycles.
