Original Press Release:

CTI-TW Thumbwheel

The NEW CTI-TW Hall Effect Thumbwheel utilizes a sealed non contacting Hall Effect sensor in a polyamide housing which can deliver up to 5 million operations. The CTI-TW was developed for thumb operated applications requiring proportional movement and virtually maintenance free reliability. This small and rugged proportional thumbwheel is ideally suited for tight clearances found in many of today’s applications where vibration, shock, and extremes of temperatures are often found. These thumbwheels are available in three mechanical configurations: (1) Spring Return to Center, (2) Spring Return to Side and (3) Friction Hold. These configurations are also available in three electrical output styles: (A) 0.5 - 4.5vDC, (B) 1.0 - 4.0vDC and (C) 0.0 - 5.0vDC. Regardless of the sensor configuration all of the CTI-TW Hall Effect Thumbwheels come prewired with 4” leads. Please contact us for color options.
