Introduction

Trimmer Potentiometers are electrical components consisting of a short cylindrical leaf that is moved around a spindle connected to a central shaft via a series of rotary springs. The trimmer potentiometer is generally connected to an electronic circuit board for control purposes. The EVM-7JSX30BE2 trimmer potentiometer is an example of a trimmer potentiometer used for various applications in industry.

Features

The EVM-7JSX30BE2 trimmer potentiometer is a three-terminal, single-turn, 10k ohm trimmer potentiometer. It is designed with stainless steel with an operating temperature range of -45°C to +125°C. It has a polystyrene insulation and an IP67 waterproof rating. The trimmer is RoHS compliant, highly durable, and is rated up to 1W.

Application Field

The EVM-7JSX30BE2 trimmer potentiometer is suitable for a variety of applications, including radio frequency (RF) amplifiers, filters, optical instrumentation, medical device controls, robotic control systems, and power supplies. Additionally, it is ideal for industrial DC motor speed control and motor control circuits.

Working Principle

The working principle of the EVM-7JSX30BE2 trimmer potentiometer is fairly straightforward. When the spindle is rotated, the resistance of the potentiometer changes according to the angle of the spindle. This alters the amount of current being supplied to the rotation mechanism, as the voltage is determined by voltage divided by resistance. Consequently, the speed and torque of the motors can be controlled depending on how much current is applied.

Conclusion

In summary, the EVM-7JSX30BE2 trimmer potentiometer is a versatile device well-suited to a variety of applications. It is a three-terminal, single-turn, 10k ohm trimmer potentiometer with a stainless steel construction and polystyrene insulation. Furthermore, it is waterproof and highly durable. Lastly, the working principle of the potentiometer is based on the changing resistance of the spindle in relation to the angle of the spindle.
