San Jose, Calif. Avago Technologies has released a series of ultra-slim scrollwheel input devices that are available in 12 standard configurations to meet the needs of designers who are developing portable handheld applications in low volumes.
The AMRX-150 scrollwheel device is also easy to install.
The AMRX-1510 scrollwheel device provides an integrated solution for scrolling, directional navigation, and pushbutton selection in the industry's thinnest package, with a 1.9-mm height and 18.5-mm diameter. The solution combines an illuminated scrollwheel input device with tactile left, right, up and down navigation switches and a center "select" button instead of many different rocker switches to enhance the user experience. In addition, the device is available with either a blue or white illumination ring, as well as a variety of material, color and finish options for the center select button and scrollwheel.
The AMRX-1510 is built around Avago's reflective optical technology , which detects the direction and speed of the rotational movement of the rotary dial. The horizontal scrollwheel provides a two-channel quadrature output with 45 cycles per revolution (CPR). It operates from a single 2.4-V to 3.3-V supply, and is available in both single-ended 1.8-V CMOS and 3.3-V TTL logic compatible output options.
The AMRX-1510 also incorporates a non-contact motion sensor to ensure reliable operation of the device. The input device comes with a FPC interconnect terminated in standard surface-mount zero insertion force (ZIF) connectors to enable designers to easily install the device in their applications.
The scrollwheel device is said to be easy to assemble, featuring plug-and-play connectivity through a flexible printed-circuit board, and requiring no signal adjustment. To maximize battery life, the device features a power-down mode in which it draws only 4 uA. The AMRX-1510 is RoHS compliant and lead free.
Pricing: Ranges from $3 to $4 each, depending on quantity and customization.
Availability: Samples and production quantities are available now through Avago's direct sales channel and distribution partners.
