PTNS1-309.7P-B01 PTNS1-309.7P-B01 Slide Potentiometer

PTNS1-309.7P-B01 is a high-quality slide potentiometer manufactured by Same Sky, a reputable name in electronic components. This particular model, part of the PTNS1 series, is designed for precise linear control in a wide array of electronic circuits. As a passive component, a potentiometer functions as a variable resistor, allowing users to manually adjust resistance within a circuit, thereby controlling parameters such as volume, brightness, or motor speed. The slide potentiometer form factor offers intuitive linear adjustment, making it a preferred choice in applications requiring smooth, tactile control over a specific range. Same Sky’s commitment to reliability ensures that this component delivers consistent performance and durability.

Key Specifications

The PTNS1-309.7P-B01 boasts several critical specifications that define its performance and suitability for various applications. Its Taper is specified as ‘Linear,’ meaning the resistance changes proportionally to the physical displacement of the slider. This is crucial for applications where a direct, predictable relationship between mechanical position and electrical output is required, unlike logarithmic tapers used for audio volume. The absence of a Detent indicates a smooth, continuous sliding motion without any tactile clicks, which is ideal for fine adjustments. The Series, PTNS1, denotes its family within Same Sky’s product line, often implying shared design characteristics and quality standards. With a Power (W) rating of 0.25 Watts, this potentiometer can safely dissipate up to a quarter-watt of power, a standard rating for many control applications in consumer electronics and industrial interfaces. The overall Size (mm) of 45mm refers to its physical footprint, important for PCB layout and enclosure design. Its Orientation is ‘Vertical,’ meaning the slider moves vertically relative to the PCB when mounted. Termination via ‘Down Facing PC Pins’ indicates through-hole mounting leads that extend downwards, facilitating secure soldering to a printed circuit board. The Mounting Type is ‘Through Hole,’ a robust and reliable method for securing components to a PCB, offering good mechanical stability. The Resistance (kΩ) is 1 kΩ, providing a total resistance range from 0 ohms to 1000 ohms. A Shaft Length (mm) of 9.7mm defines the length of the movable part that the user interacts with, influencing knob selection and panel design. The Stroke Length (mm) of 30mm specifies the effective travel distance of the slider, directly correlating to the range of adjustment. A Resistance Tolerance (%) of 20% is a common industry standard for potentiometers, indicating the permissible deviation from the nominal resistance value. Finally, an Operating Temp Range (°C) of -10 ~ 75°C ensures reliable operation across a broad spectrum of environmental conditions, suitable for both indoor and moderately harsh outdoor applications.

• Wide Operating Temperature Range: Capable of functioning reliably from -10°C to 75°C, making it suitable for diverse environments and applications.
• Compact and Versatile Design: With a 45mm size and 30mm stroke length, it offers a good balance between physical size and effective control range, fitting into various designs.

Typical Applications

The versatility and precise control offered by the PTNS1-309.7P-B01 make it suitable for a wide range of electronic applications. In audio equipment, it can be used for volume control, tone adjustment (bass/treble), or balance control in mixers, amplifiers, and soundboards, where linear response is often desired for specific parameters. For industrial control panels, these potentiometers are invaluable for setting parameters such as motor speed, light intensity in dimming circuits, or temperature setpoints in HVAC systems, providing operators with intuitive manual override. In test and measurement instruments, they can serve as calibration controls or for adjusting signal levels in oscilloscopes, function generators, and power supplies, where precise and repeatable adjustments are critical. Furthermore, in medical devices, slide potentiometers might be employed for adjusting settings on diagnostic equipment or patient monitoring systems, requiring reliable and accurate input from clinicians. Lastly, in consumer electronics beyond audio, such as home automation systems or specialized gaming peripherals, they can provide tactile control for various functions, enhancing user interaction and experience.
