WI27-1 10kb 1w 10k 20k 30k 40k Ohms Precision Conductive Plastic Rotary Potentiometer
Feature
Description
- The WI27-1 Conductive Plastic Potentiometer is a high-performance rotary control solution designed for demanding industrial and electronic applications. Featuring with golden aluminum alloy housing, a nominal resistance range of 10Ω to 2MΩ with a tight ±10% tolerance and excellent temperature coefficient of ±100 ppm/°C, it ensures stable and precise resistance adjustment. With an electrical travel of 340° ± 3° and continuous 360° mechanical rotation, the WI27-1 delivers smooth operation and accurate control.
- Engineered for durability, it offers 1W power rating at 70°C, long electrical endurance of 1000 hours at rated load, and superior resistance to vibration and shock. Its robust design withstands harsh conditions from -55°C to +125°C, while maintaining reliable performance with minimal resistance variation.
