Pinout & General Notes
Vcc should be controlled by 5.00 volts. Output is radiometric with and depends on controlled input voltage. Input should be "spike" protected if used with a vehicular power supply.
Input current is between 18 and 19 mils (0.018 to 0.019 amps) at 5.00 volts.
Input should be polarity protected; reversing Vcc and ground will destroy sensor.
Output of sensor runs between 0.34 and 0.4 volts above and below the "crossing" voltage. The crossing voltage is usually between 2.35 to 2.5 volts and may vary between different sensors, but the crossing voltages of the signals on any one sensor will match.
Maximum current draw on any output should not exceed 0.004 amps (4 mils).
Outside magnetic flux density up to approximately 1000 Gauss will not harm sensor. Outside flux exceeding 200 Gauss may create erratic indications from the sensor. No 1525 sensor is constructed to operate pins down. Sensors are damped to operate and indicate a return from a 90º displacement in approximately 2.5 to 3.0 seconds without overswing indication. Zero damping or slower damping can be furnished upon request.
Operating temperature is -20º C to +85º C. Sensor weighs approximately 2.25 grams.
