The RP22/23 potentiometers in 22 mm metal housing are suitable for applications where a accurate and compact sensor with high electrically effective rotation angle is required. Accurate wirewound potentiometer With or without mechanical end stop (32 / 36 ) Very high electrically effective angle of rotation 355 ±5 Compact sensor with 12 mm installation depth With many options The RP22/23 potentiometer series (RP23 with mechanical end stop) is a multitalent which is adaptable for a wide range of applications and is often used as a feedback sensor in valve control systems. In addition, the sensor convinces by its very good accuracy.
