Mounting
Ultrasonic transducer
The transducer mounts in a 1.54" diameter circular hole
cut into any sheet material. The transducer can be glued
using a resilient compound such as GE Silicone Sealant.
Grounding
If the sheet material is metal, surface contact to
the transducer will connect the surface to the
sensor's ground (PWR-). This is allowable as
long as it doesn't conflict with other wiring.
Circuit board
The circuit board mounts on 4 standoffs using 4-40
screws in the following hole pattern:
