Company Aurel with rich experience in the field of RF data transfer and production of thick-film technology circuits has incorporated into their products a modern technology KeeLoq (HCS). This way a whole line of products for a secure control (RKE-remote keyless entry) in the 433,92 MHz band arised. It consists of transmitters - keyfobs and receivers with a decoder. Low power consumption, high sensitivity and a high security thanks to a 64 bit crypting key (unique in every device) used to generate a 32-bit hopping code, provide an immediately usable solution for control of locks, gates and any other devices, where concurrently with the control function itself, we also need an authentification. The transmitted code changes at every sending and it never repeats, what eliminates an unauthorised access.
A receiving element is the RX-4MHCS module available in versions RX-4MHCS, RX-4MHCS/F (both with 4 output channels settable into a monostable- as well as bistable mode) and RX-4MHCS-4B (4-bit output, 12 channels). The difference between MHCS and MHCS/F is, that the „/F“ version enables to freely assign any output to any button (for example an output no. 4 to a button no. 1), while a version without an „F“ suffix will assign to the 1-st keyfob button an output no. 1, etc. Before using a keyfob + receiver set, it is necessary to program a receiver according to a simple procedure (without a computer) described in the datasheet. A great plus is a wide range of operating temperatures, enabling an outdoor use - after building into an appropriate enclosure. Receiving modules are also available as ready-made PCBs with 4 output relays in 2 versions - HCS-DEC-4 and HCS-DEC-4/F. HCS-DEC-4 modules are readily usable without any soldering or other HW development.
Transmitting elements are keyfobs with 1-12 push-buttons. On stock we keep 1-4 button versions, upon request we´re able to provide you a 6- and 12 -button version too. Receiving modules are able to operate with up to 10 keyfobs. As it is common, receivers and also transmitters (keyfobs) only cooperate if they are from the same producers, i.e. receivers can only controlled by Aurel keyfobs and similarly Aurel keyfobs can´t be used to control modules from other producers.
Further information will provide you the datasheets at particular components. On stock we also keep many other RF modules from company Aurel.
