SC304N-H 30mm Travel Single Slider Potentiometer with Iron Case and Dust Cloth
The SC304N-H 30mm slide potentiometer is a reliable linear control component designed for smooth and accurate signal adjustment in PCB-mounted electronic products. Featuring a 30mm travel length, single slider structure, iron case size of 45.3 × 8.3 × 7.0mm, and dust cloth protection, this model is suitable for applications that require stable sliding operation, precise linear control, and long-term durability.
As a single slider potentiometer, the SC304N-H is commonly used in audio equipment, mixers, equalizers, amplifiers, industrial control panels, home appliances, measuring instruments, communication devices, and consumer electronic products. Its longer 30mm travel provides a wider adjustment range, making it suitable for control interfaces that require more detailed and visible adjustment feedback.
Key Features of SC304N-H Slide Potentiometer
1. 30mm Travel for Wider Linear Adjustment
The SC304N-H is designed as a 30mm travel slide potentiometer, offering a longer adjustment stroke than compact 15mm or 20mm models. This gives users a more precise and intuitive control experience, especially in audio mixers, equalizers, dimmer controls, and user-interface panels.
2. Single Slider Structure for Stable Signal Control
This single slider potentiometer is suitable for single-channel signal adjustment. It can be used to control volume, tone, brightness, voltage, speed, signal level, or other electronic parameters that require smooth linear regulation.
3. Iron Case for Mechanical Protection
The product uses an iron case with a size of 45.3 × 8.3 × 7.0mm. This slide potentiometer with iron case structure helps protect the internal components, improve mounting strength, and support reliable performance in electronic products that require durable control parts.
4. Dust Cloth Protection for Better Reliability
The single slider potentiometer with dust cloth helps reduce dust entry during sliding operation. This design improves operating stability and supports longer service life, especially for products that are frequently adjusted by users.
5. PCB Mount Design for Electronic Control Systems
As a PCB mount slide potentiometer, SC304N-H is suitable for circuit board integration. Its slim linear structure allows engineers to design practical and user-friendly control interfaces for audio devices, industrial controllers, and consumer electronics.
