Bochen WI27-1A 10k Ohm Single Turn Precision Rotary Variable Resistor Potentiometer
Feature
Description
- The WI27-1A Conductive Plastic Potentiometer is a high-performance control component designed for precision, stability, and long service life. Featuring a compact 7/8" (22.2 mm) conductive plastic element, this potentiometer ensures smooth and accurate resistance adjustment across a nominal range of 10Ω to 2MΩ with a tolerance of ±10%. Its single-turn, bushing mount type structure allows easy panel installation, while the mechanical stop of 340°±3° guarantees reliable positioning and repeatable settings. With a temperature coefficient of ±100 ppm/°C, it provides excellent thermal stability, making it ideal for demanding environments.
- Engineered with advanced design technology, the WI27-1A combines compact size with durable construction, delivering precise electrical performance for industrial, automotive, audio, and instrumentation applications. Additionally, it supports special customization options including semicircular shafts, flat shafts, as well as long or short shaft variations, ensuring maximum adaptability to different user requirements.
