Rotary Potentiometers, Rheostats

A rotary potentiometer, or sometimes called rotary rheostat, is an electrical device used to measure angle, speed, or other variable values in a wide variety of applications. The device consists of a resistive track and a contact arm that is attached to a shaft and rotates on the track. As the arm rotates, it changes the resistance value of the device.The REL175E rotary potentiometer has a built-in range of two to five hundred degrees. The contact arm is constructed from stainless steel and has a long service life of up to one million cycles. The REL175E also features a low torque spring-loaded design which makes it easy to adjust and provides a smooth and precise operation.The REL175E has a typical application field such as:- Flowmeters- Speedometer- Adjustable speed drives- Throttle actuation- Pressure sensors- Automotive sensors- Robotics- Industrial instrumentationThe working principle of the REL175E rotary potentiometer is based on the principle of contact variation. The resistance value of the potentiometer is determined by the angle and distance of the contact arm from the central stationary contact within the resistive track. The position of the contact arm is then used to generate a variable output spanning from none to full range depending on the contact angle and type of potentiometer.When the contact arm rotates on the resistive track, the current passing through the potentiometer is altered. The peak contact voltage of the device is specified by the manufacturer and affects the value of the activated resistance. As the contact arm moves from one end of the resistive track to the other, the resistance value changes.The REL175E rotary potentiometer also features a temperature compensation which ensures that the output signal is not affected by changes in temperature that may occur during operation. The device also has a high resistance to mechanical shock, vibration, and dust which makes it suitable for use in harsh environment applications.The REL175E can be used in a variety of applications including motor speed controllers, audio amplifiers, frequency control in radios, medical imaging systems, security and automation systems, and robotics. It is also used in electrical and electronic controls such as human-machine interfaces, switchgear, and automotive components.The REL175E is an efficient, high quality, and reliable solution for these applications. The device is also simple and easy to use and is backed up by a superior customer service team who are available to help with any technical queries.
