NFC (Near Field Communication) is a variation of RFID (Radio Frequency IDentification) and extremely tamper-proof. The mo.lock digital ignition switch is used to switch the ignition on/off to a distance up to approx. 20 to 40mm. The mechanical ignition switch can be replaced by the mo.lock ignition switch, allowing a hidden mount for a clean look. It can directly switch an automotive relay of up to 40A. It comes with 2 'keys', additional keys can be purchased separately and 'learn' to switch the mo.lock. The mo-lock NFC has an RGB LED on the front which indicates the status by color. Standby current in switched-off mode is only 3.2 mA, reduces to 1.5 mA after 16 hours and after 8 days to 0.75 mA, for battery protection. The mo.lock NFC (32mm diameter x 12mm high without terminals) comes with an automotive 40A relay, mount bracket, 2 NFC keys and detailed instructions. - NFC technology is tamper-resistant - Each key has a unique code - The key first activates the mo.lock without touching it and then, via the relay, the entire on-board system - Neither key nor mo.lock NFC suffer from mechanical wear - The key requires no battery - No overload or scorched pins possible due to indirect switching via the 40A main relay - The mo.lock NFC is very compact an can be mounted hidden in many places - Water tight and vibration resistant because of the moulded-in construction - Keys can be easily purchased and 'learned' to any mo.lock NFC - your integrated locksmith - A switching distance of 2 - 4 cm ensures convenient switching while excluding the possibility of accidental engagement - An integrated RGB-LED shows the status of the mo.lock while switching, connecting and 'teaching' new keys Transmitter/receiver, diameter of installed assembly: 32 mm Height: 12 mm without terminals and bracket Weight incl. cable: approx. 35 g Mounting threads: 1 x M3 threaded hole on back side Operating voltage: 8V - 18V Operating temperature: -20 °C to +80 °C. Note: Not for use with active immobilizers. Note: See 973970 for a replacement 'key'. Note: See 973968 or 973969 for wiring kits to fabricate the wiring harness for your mo.lock ignition switch.
