If your performance requirements can be met, a low enough duty cycle can result in no heat sinking
required. With adequate heat sinking you can run continuously at 100% duty cycle.
Thermal Resistance
The measured thermal resistance from the on-board temperature sensor to the top ground plane of surface
mount carrier board is approximately 4.8°C per watt. This roughly translates to supporting 100% duty cycle
if the carrier board is maintained at 52°C or less.
Electro-Static Discharge (ESD) Specification
IEC-61000-4-2 and MIL-883 3015.7 discharges direct to operational antenna port tolerates max 2KV pulse.
NOTE: Survival level varies with antenna return loss and antenna characteristics. See ElectroStatic
Discharge (ESD) Considerations for methods to increase ESD tolerances.
Warning: The Micro antenna ports may be susceptible to damage from Electrostatic Discharge
(ESD). Equipment failure can result if the antenna or communication ports are
subjected to ESD. Standard ESD precautions should be taken during installation and
operation to avoid static discharge when handling or making connections to the
Micro reader antenna or communication ports. Environmental analysis should also
be performed to ensure static is not building up on and around the antennas,
possibly causing discharges during operation.
Authorized Antennas and Cables
M6e-Micro/M6e-M have been designed to operate at a maximum output power of 30 dBm with the
antennas listed below and having a maximum gain of 6 dBiL. Antennas having a gain greater than 6 dBiL in
any orientation are strictly prohibited for use with this device without regulatory approval. Antennas of the
same type as listed here, and equal or lesser gain, are permitted by FCC. The required antenna
impedance is 50 ohms.

These are circularly polarized antennas, but since most tag antennas are linearly polarized, the
equivalent linear gain, as provided, of the antenna should be used for all calculations.
Professional installation is required for operation of M6e-Micro-A/M6e-M-A. Only similar antennas with the
same or lower gain, and cables with or without additional adapters or connectors with the total loss the
same as or higher than the total loss specified in the following 2 tables can be used to connect to the M6e-
Micro-A or M6e-M-A without violating FCC regulations. It is the responsibility of the professional installer to
comply with this requirement.
