PHYSICAL CHARACTERISTICS
The circuit board for the HMR4007 Linear Position Sensor is approximately 340mm by 80mm. A 6-pin right angle
connector (J1) and two 4-pin connectors (J2, J3) protrude from the back of the board for user connections.
Components on the top-side have a maximum height of 12mm. Figure 1 shows a typical circuit board with
dimensions.
