PRODUCTS DETAILS

◆ Outline

九州appwhen the “s” pole of magnet faces the mark surface of the sensor and is closed to sensor (b≥bop),the sensor outputs low level; when magnet is far away from sensor(b≤ brp),the sensor outputs high level. when the “n” pole faces the mark surface,the sensor is no response. stable hysteresis((bh= |bop- brp|)ensure the stable sensor’s switch status. the magnet and electric transfer characteristic curve is shown as the figure:
