0717 series sensors can be mounted directly on the board
0703 series sensors can be mounted externally and connected with wires
All Fredericks electrolytic tilt sensors require a basic electrolytic tilt sensor circuit to generate a tilt angle output. These are often called signal conditioners, signal conditioning boards, or electronic tilt sensors. The 0717 series dual/two-axis tilt sensors can be mounted directly on these boards for a complete inclinometer solution. Other single/one axis 0703 series and glass tilt sensors must be mounted externally and connected with wires.
