Electronic Lock Keypad with Advanced Touch Sense Technology!!

• Key strikes are detected through solid material such as glass
• Capacitive Touch Sense technology is a reliable alternative to mechanical or membrane keypads - There are no moving parts to wear out or corrode over time
• Entering the correct combination closes a relay circuit that can be used to drive an electronic lock solenoid, garage door opener, or other such device
• Combination is user programmable - over 576 Billion possible combinations!
• Two modes of operation:
• Normal lock operation: The combination is entered to open the lock.
• One-time-use combo mode: User enters a new combination for each lock/unlock cycle. This mode is useful for public locker type applications
• Senses touch through any non-conductive material such as glass, plexiglass, tile, wood, plastic, drywall, etc.
• Sensitivity of the Touch Sense circuitry is adjustable to support a wide range of overlay materials and thicknesses - up to 1" thick or more
• Either use the provided 4x4 keypad PCB or create your own custom touch sense keypad using any conductive material such as copper, copper clad board, or even some random small metal objects. No one would even know its your security keypad!
• Optically isolated relay control circuit can drive a small DC load directly or it can be connected to a power MOSFET to drive larger loads
• On-board beeper and LED provides audible and visual feedback when touch is detected
• Applications:
• Garage door opener keypad
• Replacement of mechanical or membrane keypads
• Replace old faulty rubber keypads with reliable solid state Capacitive Touch keypad
• Hide your electronic lock keypad behind any non-conductive surface like tile, wood, drywall, etc.
• This is an intermediate electronic kit containing 42 components, a 9V AC adaptor and 2 PCB's, and will require about 1-2 hours to assemble
• Designed and packaged in the USA
