Grayhill specializes in human interface optical encoders that provide excellent tactile feedback to the user. The greatest advantage of optical encoders is their non-contact switching technology which results in an exceptionally high operational life.
Although the end-product may vary, typical applications measure discrete digital position or rotational angle. Output options include absolute or quadrature 2-bit binary code.
Custom shaft and threaded bushing sizes are available. To increase the functions in one control, Grayhill offers optical encoders with concentric shafts, joysticks and pushbuttons integrated into compact devices.
Grayhill’s joysticks provide the human interface for directional control. They are available with mechanical switching or magnetic Hall-effect sensors for long life.
Our NavCoders are unique human interface devices for navigating through on-screen software. They integrate the following three technologies:
- 4-way or 8-way directional control to navigate through menu options
- Center pushbutton for selecting menu options
- Rotational control for scrolling through many options or adjusting an intensity setting such as volume
