Product Overview

The ACCESS-TOUCH-EVAL is an integrated combination key access controller featuring tough sensitive keys for vandal proof operation. An accompanying design blueprint is available for a complete low cost, access control product. The access touch uses capacitive touch sensing technology. The PCB keyboard shown can be overlaid by a non metallic covering. It automatically calculates signal averages to compensate for track capacitance, water splashes, etc. A buzzer output provides audio feedback as buttons are pressed. When the correct code is entered, the door release output is activated for a fixed time delay. The sequence of keys pressed prior to entering the code is unimportant. To change the access code, an electrical switch is closed and the new code is entered twice. LEDs indicate open, closed and set code states. All LEDs turn off when the device enters a sleep state.
  • Vandal proof design, no parts need to be physically exposed
  • Codes may be up to eight digits
  • Audio feedback on touch press
  • Safe controller mode available
  • 20pin SSOP package
