Trimmer Potentiometers are resistors with a precisely adjustable resistance setting. It is most commonly used for output matching in radio communications, precision control of audio frequency signals and in motor control automation.

The ST5ER100 series is a range of trimmers from CTS that provide excellent performance in applications with a range of requirements. Featuring a low profile design and an extended contact length, they are designed for use in industrial, automotive and in a variety of other demanding applications.

The ST5ER100 series is designed with several features in order to provide superior performance in a wide range of applications. This includes enhanced stability, high voltage rating, superior temperature range and long life. It is also designed with a low profile design, extended contact length and low profile for maximum versatility.

The ST5ER100 trimmers feature a precise resistance setting with a typical adjustment accuracy of 0.1ohms. This allows the user to fine-tune or calibrate the resistance to a desired value. This feature is particularly useful in applications such as motor control automation and radio communications.

The ST5ER100 trimmers also feature a high voltage rating of 1000V DC and a temperature range of -40°C to +130°C. This combination of features makes the ST5ER100 ideal for applications that are exposed to severe climate conditions and high levels of electrical interference.

The working principle of the ST5ER100 is based on a small contact strip, usually made from a cobalt-containing metal, which is located in the middle of the housing. This contact strip contains multiple contacts that can be moved to change the resistance setting. The contact strip is held in place by four O-ring seals, which provide excellent environmental protection and prevent the contacts from slipping or becoming loose.

The ST5ER100 also features a self-locking device that maintains the resistance setting over long periods of time. This is an important feature, as it allows the device to maintain a precise setting in high vibration environments. Additionally, the device does not require any lubricants, greatly enhancing its life-span and reliability.

The ST5ER100 series of potentiometers is an excellent choice for a wide variety of applications. The high voltage rating, extended contact length and low profile design as well as the precision adjustment accuracy make it especially suitable for industrial settings and radio communications.
