Notes:
1. In reference to internal reader signal level.
2. Under conditions specified in the Measurement Environment (see following pages). Specifications for the sensor have been established by using the SenGenuity WSR-T2 Wireless SAW Reader. See reader specification sheet
for information on standard set up of reader hardware.
3. Decay of time domain response envelope, measured with 4MHz span around center (resonant) frequency.
4. Δf[Hz] = TCf(ppm/K) x (T - To) x fS[MHz]
5. For 1000h continuous operation at maximum operating temperature.

Stability Characteristics and Reliability
After the following tests the sensor shall meet the whole specification:
•
Shock:
500g, 1 ms, half sine wave, 3 shocks each plane;
DIN IEC 68 T2 - 27
•
Vibration:
10 Hz to 500 Hz, 0,35 mm or 5 g respectively, 1 octave per min, 10 cycles per plan, 3 plans;
DIN IEC 68 T2 - 6
•
Change of temperature:
-55 °C to 125°C / 15 min. each / 100 cycles;
DIN IEC 68 part 2 – 14 Test N
•
ESD:
MIL-STD-883E using coupling network of ISO 10605 and EN 6100-4-2;
HBM:250V
•
Impact Strength:
1J , rod pendulum, impact at upper edge of sensor module cap
(may occur only once in sensor module lifetime)
This sensor is RoHS compliant (2011/65/EU)
Measurement Environment
Specified electrical properties shall be measured under the following test conditions
1.
Ambient temperature:
25°C
2.
Humidity:
30% - 60%
3.
Distance sensor antenna to reader antenna:
80cm (signal path shall have minimum free 1st Fresnel zone)
4.
Anechoic environment:
Reflected RF signals (multipath echos) should be attenuated minimum 25 dB in
reference to direct signal between reader / sensor module
5.
Inband interferer:
Outside signals in the measured frequency range shall be attenuated by 40 dB in
reference to reader Tx signal power
6.
Sensor mounting:
Sensor module has to be mounted on a ground plane perpendicular to sensor
module antenna rotation axis
7.
Antenna alignment:
Rotation axis of sensor module and reader antenna have to be parallel and
perpendicular to transmission path
The frequency and signal level is influenced by reactive interaction to materials within the reactive near field, approximately 17.5 cm. For
a description of an example implementation of these requirements see application note Sensor Module Test Setup.
