Advanced Input Systems' Flat Panel Series is designed for environments where instrumentation
needs to be highly visible, cleanable, and impervious to surrounding elements.
OVERVIEW
Designed to meet demanding requirements, Advanced Input Systems' Flat Panel series is particularly popular and reliable in environments
where instrumentation requires high visibility, cleansing, and the ability to withstand harsh operating conditions.
Flat Panel keyboards utilize flat panel, tactile or non-tactile touch with multiple switch technology options: dome switch or membrane switch. The tactile dome product supplies a crisp snap-action breakover tactile feel for optimal operator accuracy. The non-tactile membrane adapts the simplest of switches with silver ink screened on polyester.
Flat Panel products are used in applications that require an easy-to-clean keyboard, and the ability to operate in a severe and exacting environment.
