Appendix 3: Frequently Asked Questions

Additional questions about the sensor are addressed here.
1. Q: What are the primary factors distinguishing the M8 from competing sensors?
A: Quanergy's M8 LiDAR sensor is typically superior in terms of price, IP69K-rated
ingress protection, longer range, higher angular resolution, points per second,
reliability, and ability to deal with adverse weather.
2. Q: Where is the serial number of the M8 sensor?
A: The entire serial number is printed on the manufacturing label that is affixed to
both the rectangular base plate and the round mounting base, as shown in Figure 1.
3. Q: What is the voltage range for the M8 sensor?
A: 24 VDC ± 1.2 V.
4. Q: How robust is the M8 sensor in terms of electromagnetic compatibility (EMC)?
A: The sensor passed tests for the following EMC compliance specifications:
EN 61000-4-2 ESD
EN 61000-4-3 RF Immunity
EN 61000-4-4 EFT
5. Q: Under what lighting conditions will the M8 sensor work?
A: The M8 sensor works well under all lighting conditions. Quanergy tested the
sensor by operating it on extremely bright and sunny days, and the performance was
not affected. And in dark, zero-lighting conditions where vision-based systems are
challenged, the sensor's performance was not affected.
6. Q: Does the M8 sensor work underwater?
A: No. 905 nm light is absorbed by water.
7. Q: Why does the M8 sensor have eight lasers?
A: This was the perceived optimum for the main target applications of transportation,
security, industrial automation, and mapping.
8. Q: When does the M8 sensor's motor start and stop?
A: The sensor starts upon establishing the socket connection, and it stops after
terminating the socket connection. So the sensor's socket connection determines
when the motor starts and stops.
