REL250E is a kind of rotary potentiometer, rheostat with some special characteristics. REL250E is one of the most popular products in the industry due to its wide range of applications and superior performance. This article will discuss the application field and working principle of REL250E.

REL250E, also known as low-power, high-performance rotary potentiometer, is widely used in a variety of applications, including computing, testing, medical devices, aerospace, and defense. It is mainly used to adjust or measure in a broad range of circuits, such as the voltage-controlled oscillator, AC voltage controller, AC motor controller, and DC motor speed or current controller. With its three-point construction and the right rotor shaft design, REL250E can be adjusted precisely to any desired resistance value. In addition, its alloy body with no sealant provides high reliability and long-term stability, even in harsh environments.

The working principle of REL250E is based on the wiper principle. The rotating wiper contact in the device slides along the resistor surface so that the resistance between the two end terminals can be adjusted and measured without any physical connection between them. When the potentiometer is rotated, a spring-loaded pinion gear contacts the resistive track on the metal substrate, and the contact point moves along with the rotation. The resistance between the two terminals can be adjusted by changing the position of the wiper contact, and the resulting resistance will be indicated on the scale.

REL250E also offers precision temperature tracking, equal resistance coefficient, and perfect logarithmic characteristic in operation. It also features a high longevity, such as a guaranteed life of a minimum of 1.5 million full turns and more than 10 million cycles. Besides, it is able to operate in wide temperature ranges, from -55℃ to +125℃. It is also vibration, shock, humidity, and corrosion resistant, making it not only long-lasting but also extremely reliable. And its compact size and low cost make it the choice of many manufacturers.

In conclusion, REL250E is a kind of rotary potentiometer, rheostat which is widely used and has many characteristics. Its wide range of applications and superior performance make it one of the most popular products in the industry. The working principle of REL250E is based on the wiper principle, while the wide temperature range and resistance coefficient make it an ideal choice for a range of applications. Its precise temperature tracking and logarithmic characteristics make it an excellent component for accurate and reliable circuit adjustment, while its compact size and low cost make it reliable and economical.
