Electro-Static Discharge (ESD) Specification
The Electro-Static Discharge Immunity specifications for the 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.
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.
Shock and Vibration
The 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 Grms 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.
