The Ohmite 111-8 is a high-quality linear potentiometer designed for various applications where precise voltage control is required. This potentiometer comes in an elegant, compact package, measuring 1.2 inches (30.5 mm) in length and 0.5 inches (12.7 mm) in diameter. The length of the shaft is a convenient 0.7 inches (17.8 mm), providing ample space for easy adjustment.
The 111-8 potentiometer from Ohmite boasts a resistance value of 1 Megohm (1,000,000 ohms) at 25 C with a 2% tolerance, ensuring consistent performance under various conditions. This potentiometer is a three-terminal type, with one terminal for the wiper, one for the fixed end, and one for the resistive element's other end, which is typically grounded.
The Ohmite 111-8 potentiometer has a maximum power rating of 0.25 watts, making it suitable for low-power applications. Its operating temperature range is between -30 C and 70 C. The potentiometer's shaft is knobless, allowing for a smooth, low-profile design and can be easily customized with various knob options if desired.
This potentiometer features a linear taper, which provides a consistent resistance change as the shaft is rotated. The wiper's contact resistance is minimal, ensuring reliable voltage transmission as the potentiometer is adjusted. The Ohmite 111-8 potentiometer is also RoHS compliant, ensuring that it meets the latest environmental standards.
The 111-8 potentiometer from Ohmite is an excellent choice for those seeking a high-performance, low-profile, and versatile voltage control solution for their projects or applications. Its consistent resistance change, minimal contact resistance, and wide operating temperature range make it a reliable and versatile component for various applications in the fields of electronics, automation, and control systems.
The Ohmite 111-8 potentiometer is a linear volume control potentiometer with a 1/4 inch bushing and a 1M Ohm resistance. Here are some pros and cons of buying this potentiometer:
Pros:1. High resistance value: With a resistance of 1M Ohms, this potentiometer is suitable for applications where a high resistance value is required for voltage division or attenuation purposes.
2. Linear taper: The linear taper of this potentiometer ensures that the resistance changes linearly with the rotation of the shaft, making it ideal for volume control applications.
3. Robust construction: The Ohmite 111-8 potentiometer is known for its robust construction, which makes it suitable for industrial and commercial applications.
4. Wide operating temperature range: This potentiometer can operate in temperatures ranging from -30 C to 85 C, making it suitable for a wide range of applications.
Cons:1. High price point: Compared to other standard potentiometers, the Ohmite 111-8 potentiometer has a higher price point due to its high resistance value and robust construction.
2. Large size: With a diameter of 2.2 inches and a length of 3.5 inches, this potentiometer is larger than standard potentiometers, which may not be suitable for space-constrained applications.
3. Requires external components for voltage division: To use this potentiometer for voltage division applications, external resistors are required, which adds to the complexity of the circuit.
Conclusion:The Ohmite 111-8 potentiometer is a high-quality, robust potentiometer suitable for industrial and commercial applications where a high resistance value and linear taper are required. Its wide operating temperature range and linear taper make it ideal for volume control applications. However, its high price point and large size may be a disadvantage for some applications.
Recommendation:If a high resistance value and linear taper are essential for your application and you have the budget and space for a larger potentiometer, the Ohmite 111-8 potentiometer is an excellent choice. However, if you have space and cost constraints, a standard potentiometer with a lower resistance value may be a more suitable option.
