This four button OEM USB keypad offers design engineers a convenient user interface for implementing new software application features. A Software Application Developer can utilize the pre-defined codes outlined in the USB Specification Standard that are available through API libraries of the USB HID Compliant Keyboard Device Driver on a Windows OS® platform. Most keyboards manufactured today only offer the Function 1 (F1) through Function 12 (F12) keys, thus some operation systems (i.e. Windows OS®) and software applications do not take advantage of the Function 13 (F13) through Function 16 (F16) keys. The F13 through F16 keys have pre-defined, unique, codes available via the USB HID Compliant Keyboard Device Driver (USB HID Usage ID HEX Codes 68, 69, 6A, 6B) that can be implemented to provided additional functions for a software application.

CTI’s miniature USB keypads when installed provide a NEMA 4 (IP66) watertight sealing protection. CTI’s specially formulated SYN-Proof™ coating provides the silicone rubber keypad with additional protection against harsh oils and solvents. The design of these miniature USB keypads ensures years of reliable service and durability through the use of hard carbon pill contacts molded into the silicone rubber elastomer with a thick layer of hard gold plated onto the printed circuit board. With an operating temperature range of -40°C to +80°C (-40°F to +176°F) these miniature USB keypads have been ruggedized to meet aerospace, marine, medical, and military standards.
