Environmental Specifications
Thermal Considerations
The module will operate within its stated specifications over a temperature range of -40° to 65°C at
mounting surface.
Thermal Management
Heatsinking
No heat Sync Required up to 65°C
Temperature Sensor
ThingMagic M3e module has an integrated temperature sensor, located near the components which
generate the most heat. The temperature can be obtained through the user interface as a status indication.
This information is also used by the firmware to prevent transmission when the module is too hot or too cold
to operate properly. The Operating Temperature limits for allowing transmission are -40°C to +65°C (case
temperature).
NOTE: The temperature level at which transmission is prevented, +85°C, is higher than the +65°C
operating limit for two reasons: (1) The temperature indicated by the on-board sensor will always
be higher than ambient temperature, due to heat generated by internal components, and (2) the
temperature limit for transmission is chosen to prevent damage to the components, while the
+65°C limit for operation is chosen to ensure that all specifications are met.
Electro-Static Discharge (ESD) Specification
The Electro-Static Discharge Immunity specifications for ThingMagic M3e are as follows:
IEC-61000-4-2 discharges direct to operational antenna port tolerates max 1.5 KV contact discharge.
It will tolerate a 1.5 kV air discharge on the I/O and power lines. It is recommended that protective
diodes be placed on the I/O lines.
NOTE: Survival level varies with antenna characteristics. See ElectroStatic Discharge (ESD) Considerations
for methods to increase ESD tolerances.
Warning: The ThingMagic M3e antenna port 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 ThingMagic M3e 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.
Shock and Vibration
ThingMagic M3e module is specified to survive a 1-meter drop onto a hard surface. It will also survive the
following vibration limits:
18 shocks (3 in each direction of 3 different axis) of 1000g at 23˚C applied via the mounting surface.
Sinusoidal vibration of 1.0” peak-to-peak displacement from 5 to 13 Hz, 10g acceleration from 13 to 500 Hz
