Together, these three attributes, any one of which represents a significant improvement over prior devices , form a truly revolutionary advance in the state of the art of keypad design. Patents granted and pending. The FDIT Keypad allows an OEM manufacturer or system integrator to greatly enhance the quality and reliability of their products. Custom FDIT Keypad layouts are easily generated, and any host communication software module may be selected. Naturally, a custom designed FDIT Keypad can be interfaced to any logic standard, such serial Async communication.
Cost alone is competitive with membrane technology, when the keyboard encoder is considered.
Keypad may be hermetically sealed, rendering it impervious to dust, moisture, spillage, and corrosive or explosive vapors. FDIT Keypad units continually and automatically re-calibrate field sensitivity to compensate for environmental changes and component aging. They are completely unaffected by vibration, humidity, and temperature variations. Operation is unaffected by protective gloves, yet the FDIT Keypad can discern between a finger and a dropped object or projectile. Extremely low RFI and EMI emissions susceptibility and radiation.
