TM7EW103

Trimmer Potentiometers

The TM7EW103 is a trimmer potentiometer which offers superior performance in a small, compact housing. It features a vertical type switching shaft for adjusting trimmer positions. Its goal is to provide precise, economical tuning of analog circuits. Its wide range of application includes the tuning of radio receivers, television sets, industrial and telecommunication equipment, and precise automation.

Application Field

TM7EW103 trimmer potentiometers can be applied to various tuning or control tasks, including the adjustment of frequency and gain of various instruments, adjust audio records, control display brightness and electroacoustics in quadrophonic sound systems. It can also be used in the assessment and adjustment of echo and attenuation of various broadcast signal devices. Its small size and vertical operation make it suitable for use in narrow spaces.

Working Principle

The TM7EW103 trimmer potentiometer uses a standard single-turn structure to provide precise, economical control. It is also multi-turn design, which allows for more precise setting. The resistance value of the trimmer potentiometer can be adjusted accurately and rapidly with a turndial. The turndial also features the ability to switch between different rotation directions. By shifting the direction of rotation, the range of adjustment of the resistance value can also be adjusted.When the potentiometer is adjusted, the resistance value of the resistor connected to the shaft can be changed accordingly. When the turntial is turned, the resistance inside the potentiometer varies and is sensed by a contact along the shaft. Thus, a quite small improvement in the resistance value of the resistor can be obtained by precisely moving the contact along the resistant track.

Conclusion

The TM7EW103 trimmer potentiometer is a superior and reliable device suitable for various tuning or control tasks. Its vertical switch structure makes it especially versatile and suitable for adjusting in narrow spaces. Its single turn or multi-Turn design with precise control allows you to get the desired tuning results. With its improved accuracy, it is suitable for use in a wide range of applications.
