The linear motion potentiometers series PN231 have a 31 mm square section housing, 8 mm diameter shaft and two fixing ball joints at the ends. Their measuring strokes range from 50 to 750 mm, and their standard resistive value is 5 KOhm. The conductive plastic resistive element grants the transducer a long life (100,000,000 motions), high independent linearity and virtually infinite resolution. The electrical connections are granted by means of M12 connector. Thanks to their high protection degree against environmental agents the potentiometers series PN231 are suited for severe applications, even outdoors, at extreme temperatures. AVAILABLE STROKES mm 50 – 100 – 150 – 200 – 250 – 300 – 400 – 500 – 750 AVAILABLE RESISTIVE VALUES 5 Kohm (standard) – 10 Kohm on request TECHNICAL SPECIFICATIONS conductive plastic resistive element 100,000,000 operations life infinite resolution excellent linearity moving speed up to 5 m/sec. shaft diameter 8 mm stout aluminium housing easy fixing by ball joints 8 mm diameter or movable clamping brackets electrical connections by M12 connector operating temperature: -20° ÷ +80° C IP65 protection degree 2 ball joints at the ends, 8 mm diameter
