Description: These are being used to prevent theft of autos, provide increase security in buildings, to operate electronic gates, garage doors, computers,etc. Consists of a small key fob that is totally self contained (no moving parts or batteries) and a proximity sensor and associated receiver circuit box. When the key fob is brought within 3 inches of the sensor, the unique date incoded in the key fob is transfered to the sensor-receiver, activating whatever device-relay, solenoid, light, locks, etc.- that you have connected to the receiver. These are brand new units consisting of two key fobs, a master programer key in a sealed container, and a receiver box with sensor. The receiver is very sophisticated and can not be activated except by the key fobs that come with it. If someone steals one of the key fobs, you may program a new code with the master programer key fob into a remaining fob so that the stolen one will no longer work. The coding of new keys does not use a compute and can easily be completed in a few second period. The system is absolutely amazing. The reciever operates on 12 VDC Details: The key fob is completely waterproof, and crunch resistant.

The sophisticated receiver uses 6 ICs and have 12V OUT PUT WHEN TRRIGER . when the correct key fob is brought within 3 inches of the sensor. THE UNIT PUTS OUT 12V OUT PUT (MUST BE WIRED TO 12V REALAY), and when key removed from sensor relay will open.This new technology has thousands of applications. As soon as you buy one of these units you'll want to purchase more as you realize all the different ways it can automate or control security tasks. Brand new with complete instructions,UNIT WILL COME WITH COMPLET WIRING DIAGRAM. This is ideal for the electronic hobbyist wishing to build a simple electronic high security door locking system. The kit consists of an RFID reader coupled with a 125KHz antenna. The kit comes with two RFID keyfob tags. Extra tags are available in two formats, Keyfob or Disc. The Keyfob as it's name suggests can be attached to a keyring, whilst the Disc can be put into a wallet or purse. The read range is 50mm - 75mm. The tags have unique serial numbers allowing only tags which have been programmed in to the RFID reader by the master programming fob to activate the reader output. The reader has a 12v output which is active for as long as the keyfob is held in front of the RFID reader's antenna. This output can be used to drive a relay which in turn unlocks a door latch. The reader unit runs from 9V to 15V DC. you get 3 units!!! You can program up to 25 RFID keyfobs per reader. look at item 251779995500 if you need more key fobs look at my listing 250930163421 4 units look at my listing 252287544185 relay board 3 mode relay board, momentary- momentary delay- bi stable flip flop
