Circuit cannot be damaged by magnetic overdrive. * Absolute maximum ratings are the extreme limits that the device will withstand without damage to the device. However, the electrical and magnetic characteristics are not guaranteed as the maximum limits (above recommended operating conditions) are approached, nor will the device necessarily operate at absolute maximum rating. LEADWIRE COLOR CODE Vs (+) Ground (-) Output (Digital) NOTICE Do not reverse supply voltage polarity. Do not exceed maximum ratings.

Make certain wiring is correct (load must be connected). 2. Measure supply voltage across the Red (+) and Black (-) leads to verify that proper supply voltage is present. 3. Connect positive lead of voltmeter to White (output) lead, and negative voltmeter lead to Black (-) lead. With magnet removed (or north pole present), the reading should equal Vs. 4. When the magnet (south pole) moves toward sensor face (beyond operating point), the sensor output should be 0.40 VDC. CURRENT SINKING OUTPUTS (Current flow through load into sensor.) Output terminal is open collector. In the unoperated condition (IL = 0), the output voltage is normally high.
