1D Hall-effect latches share similar operational characteristics as switches, but uniquely retain the previous output state until a magnetic pole of the opposite polarity is detected. Therefore, it is necessary that the sensor detect changing magnetic polarities to create corresponding changes on the output. Assuming equal spacing of magnets, the output waveform of a latch is approximately 50% duty cycle regardless of sensing frequency. Figure 2-5 demonstrates the operational characteristics of a Hall-effect latch.
