EWV-YE, Center Space Potentiometer
More Flexibility For Function Integration
Panasonic, a worldwide leader in electromechanical components,
introduces the NEW EWV-YE Series of Center Space Potentiometers.
Center Space Potentiometers are frequently used in automotive and audio/
visual applications, to integrate control functions and reduce cluster.
Compared with Encoders, Potentiometers offer absolute position control.
The EWV-YE Potentiometer comes with a large hollow center at 20mm diameter. Designers have plenty
of room to put LEDs, switches and other components in this center space. In addition, the large rotation
ring provides a smooth and comfortable grip for users. EWV-YE comes with 3 standard detent options,
29 detents for temperature control, 8 detents for fan speed, and 5 detents for mode adjustment. Other
options include integrated LED, low torque and customized detent positions to suit specific needs.
Panasonic also offers many other Center Space Encoder and Potentiometer solutions to suit your needs.
Features:
•Large center space of 42.4mm diameter
•Low wobble of 0.25mm max
•Multiple detent options (5, 8, 13, 29)
•Automotive operating temperature
Benefits:
•Function integration
•Space saving
•Comfortable rotation
•Robust endurance
