PTN092-V100115K1A PTN092-V100115K1A Rotary Potentiometer

PTN092-V100115K1A is a high-quality logarithmic rotary potentiometer manufactured by Same Sky, a reputable provider of electronic components. As a crucial passive component, this rotary potentiometer is designed for applications requiring precise control over an electrical signal, typically volume or tone in audio circuits, due to its logarithmic taper. It functions by varying resistance as the shaft is rotated, thereby modulating current or voltage in a circuit. This specific model features a dual-gang configuration, allowing for simultaneous control of two independent channels, making it highly versatile for stereo audio applications or other dual-channel control systems.

Key Specifications

The PTN092-V100115K1A boasts several key specifications that define its performance and suitability for various applications:

Taper: Logarithmic – A logarithmic taper (also known as audio taper) means the resistance changes exponentially with rotation. This is ideal for audio volume controls because human hearing perceives sound intensity logarithmically. Using a linear taper for volume would result in most of the perceived volume change occurring at one end of the rotation.

Detent: No Detent – The absence of detents means the shaft rotates smoothly and continuously without any tactile clicks or stops. This is preferred in applications where fine, uninterrupted adjustment is necessary, such as precise audio mixing or continuous parameter tuning.

Series: PTN09X – Belonging to the PTN09X series indicates a standardized design and form factor, ensuring compatibility and consistent performance across products within this family. This series is known for its compact size and robust construction.

Switch: No – This potentiometer does not integrate an on/off switch. This simplifies the component and is suitable for designs where power switching is handled by a separate mechanism.

Bushing: 5 mm – The 5 mm bushing provides a standard mounting diameter, ensuring compatibility with a wide range of panel cutouts and mounting hardware. This contributes to ease of integration into various enclosures.

Power (W): 0.05 – With a power rating of 0.05 Watts, this potentiometer is suitable for low-power signal control applications. It is designed to handle typical signal levels in audio and control circuits without overheating.

Size (mm): 9.5 – The compact 9.5 mm body size makes this component ideal for space-constrained designs, allowing for higher component density on PCBs or smaller product footprints.

Orientation: Vertical – A vertical orientation means the potentiometer stands upright on the PCB, which can be advantageous for certain enclosure designs or when maximizing board space in a particular dimension.

Shaft Style: Knurled (18 Teeth) – The knurled shaft with 18 teeth is designed for easy gripping and secure attachment of standard knob types. The knurling ensures a firm connection, preventing slippage during adjustment.

Termination: Straight PC Pins – Straight PC pins are optimized for through-hole mounting, providing a robust mechanical and electrical connection to the printed circuit board. This termination style is reliable for manual or automated assembly.

Mounting Type: Through Hole – Through-hole mounting offers excellent mechanical stability, making the component resistant to vibration and physical stress. It is a common and reliable mounting method for panel-mounted components.

Rotation (°): 300 – A 300-degree electrical rotation provides a wide range of adjustment, allowing for fine-tuning across the full resistance range. This ensures precise control over the desired parameter.

Number of Gangs: 2 – The dual-gang configuration means two independent potentiometers are operated by a single shaft. This is crucial for stereo audio applications where left and right channels need to be adjusted simultaneously, or for controlling two related parameters in a system.

Number of Turns: 1 – Being a single-turn potentiometer, the full resistance range is covered within one complete rotation of the shaft. This offers quick and direct adjustment, suitable for most user interface controls.

Resistance (kΩ): 100 – A resistance value of 100 kΩ is a common and versatile choice for many audio and general-purpose control applications, providing a suitable range for signal attenuation or voltage division.

Shaft Length (mm): 15 – The 15 mm shaft length provides ample extension for mounting through panels of varying thicknesses, accommodating different enclosure designs and knob styles.

Resistance Tolerance (%): 20 – A resistance tolerance of ±20% is standard for general-purpose potentiometers, indicating reliable performance for most non-precision control applications.

Operating Temp Range (°C): -10 ~ 75 – This broad operating temperature range ensures the potentiometer functions reliably across typical environmental conditions encountered in consumer electronics, industrial controls, and other applications.

Features and Benefits

• Dual-Gang Logarithmic Taper: Ideal for stereo audio volume and tone control, providing balanced and natural sound adjustment across two channels simultaneously.
• Compact and Robust Design: The 9.5 mm body size and through-hole mounting ensure durability and suitability for space-constrained applications, offering reliable performance over time.
• Smooth, Continuous Rotation: The ‘No Detent’ feature allows for fluid, uninterrupted adjustments, enhancing user experience in applications requiring fine control without tactile feedback.
• Standard Knurled Shaft: The 18-tooth knurled shaft is compatible with a wide array of standard knobs, simplifying product design and assembly while ensuring secure knob attachment.
• Wide Operating Temperature Range: Reliable performance from -10°C to 75°C makes it suitable for diverse environments, from consumer electronics to light industrial equipment.

Typical Applications

The PTN092-V100115K1A rotary potentiometer is highly versatile and finds application in numerous electronic systems:

Audio Equipment: Its primary application is in audio amplifiers, mixers, and equalizers for volume, balance, and tone control. The logarithmic taper is crucial for a natural listening experience, especially in stereo systems where the dual-gang configuration allows for simultaneous adjustment of left and right channels.

Consumer Electronics: Used in various consumer devices such as radios, home theater systems, and portable audio players for user-adjustable settings like brightness, contrast, or other parameter controls where a smooth, continuous adjustment is desired.

Musical Instruments and Pro Audio Gear: Integrated into guitar amplifiers, synthesizers, effect pedals, and professional audio consoles for adjusting parameters like gain, frequency, or modulation depth. Its reliability and smooth operation are valued in performance-critical environments.

Industrial Control Panels: While primarily an audio taper, it can be used in certain industrial human-machine interfaces (HMIs) for non-linear control of process variables, where a fine adjustment at one end of the range and coarser adjustment at the other is acceptable.

DIY Electronics and Prototyping: An excellent choice for hobbyists and engineers developing prototypes, providing a standard and reliable component for experimenting with variable resistance in circuit designs, especially those involving audio or sensor calibration.

In summary, the Same Sky PTN092-V100115K1A is a reliable and versatile dual-gang logarithmic rotary potentiometer, ideal for a broad spectrum of applications requiring precise and smooth signal control.
