Working Principle

The 3310Y-125-203L is a single-turn rotary potentiometer, which works on the principle of voltage division. It is designed with a circular conductive track, which is divided into several sections. As the movable contact of the potentiometer is rotated, the resistance between the adjustable contact and the track is changed, and the output voltage is proportional to the resistance. Thus, by varying the resistance, the output voltage can be controlled.

The 3310Y-125-203L consists of a potentiometer body, which houses the contact and the track. The contact is connected to an external terminal via a lead. A spring-loaded plunger is also attached to the contact, which allows it to move freely on the circular track. As the plunger moves, the resistance between the contact and the track is modified, thus changing the output voltage.

The potentiometer body is also enclosed in a housing, which helps protect it from environmental contingencies. The housing also helps protect the track from dust and other particles, which can interfere with its operation. Depending on the application, a variety of housing materials are available, such as aluminum, brass, or polycarbonate.

Conclusion

The 3310Y-125-203L is a rotary potentiometer from the 3310Y series, which is suitable for a wide variety of applications. It works on the principle of voltage division, and its output voltage can be adjusted by varying the resistance between the contact and the track. It is enclosed in a protective housing, which helps protect it from environmental contingencies.
