Datasheet

Make sure there are no vias or exposed

metal underneath the EC OEM

™

circuit.

Designing your PCB

Create the traces as short as possible from the EC OEM

™

circuit to your probe connection.

Keep the traces on your top layer, keep a distance of 1mm for any other trace. use 0.4mm

trace width. Use a ground plane underneath the traces and probe connection.

Ground Plane

101

This cross section is an example of how the ground plane protects

the Conductivity signal. The ground plane should surround the

Conductivity signal, on the top layer as well as the bottom layer.

If pin 7(INT) is unused leave it floating,

do not connect pin 7 to VCC or ground.

Conductivity Signal

Keep the traces for both probe and

probe ground as short as possible.

Connect pin 6 to the ground plane.
