Functional Description of the MLx 125kHz Handle and MLx 13,56MHz
Handle
The MLx 125kHz (LF) and MLx (HF) 13,56MHz Handles offer a general RFID reader
functionality, powered by an external 5V DC voltage source. The MLX Handles are used in
combination with the MLx Readers (e.g. MLx2000, MLx3000 and MLx5000), that control
the Handles RFID transponder reading functionality via a 2-wire data bus. The Handles
RFID functionality includes reading of several types of 125kHz (e.g. HITAG) or 13,56MHz
ISO transponder (e.g. ISO15693, ISO14443) types.
The µP of the MLx Handles is clocked by a 16MHz-Resonator. The active components are
powered by 5V from an external linear LDO regulator (located on the MLx Readers). The
125kHz-Reader IC (P4097) drives the 125kHz coil antenna. The 13,56MHz Reader IC
(CLRC663) drives a 13,56MHz coil antenna respectively.
When reading a valid transponder, the data is sent via the data bus. The external MLx
Reader identifies and returns a signal on the data bus to unlock the actuator of the handle.
If a handle has an actuator, the MLx handle then controls the actuator and unlocks.
This actuator is usually a 12V permanent magnet motor, which unlocks the handle, so the
user can get access to a door, or compartment, e.g.
In case the Handle has a Keypad, the user can enter a digit code to get access on a 12-
digit keyboard located in the handle front side. However the keypad functionality is
optional, it does not affect the RFID functionality. The status of the Handle is shown to the
user by RGB LEDs.
All LF and HF handles share the same RFID reader functionality.
