ThingMagic Nano User Guide 16
www.JADAKtech.com
ThingMagic Nano 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 +60°C (case
temperature).
NOTE: The temperature level at which transmission is prevented, +85°C, is higher than the +60°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
+60°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 Nano are as follows:
IEC-61000-4-2 and MIL-883 3015.7 discharges direct to operational antenna port tolerates max 1 KV
pulse. It will tolerate a 4-kV air discharge on the I/O and power lines. It is recommended that protective
diodes be placed on the I/O lines as shown in the carrier board schematic diagram (see Hardware
Integration).
NOTE: Survival level varies with antenna return loss and antenna characteristics. See ElectroStatic
Discharge (ESD) Considerations for methods to increase ESD tolerances.
Shock and Vibration
ThingMagic Nano module is specified to survive a 1-meter drop onto a hard surface. It will also survive the
following vibration limits:
• 4.02 Grams random, mounted on a non-resonant hard carrier
• Five shipments by air, MIL-STD-810G METHOD 514.6 ANNEX C, Figure 514.6C-5 General Exposure
pg. 514.6C-16, and Table 514.6C-VII, General Exposure. 5 minutes each of three axes.
Warning: The ThingMagic Nano 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 Nano 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.
