The measuring range depends on the sensor type and There, sinking outputs normally have current flowing the target, but maximum frequency is generally > 10 kHz. into the device output lead when the device is active. The target geometry must be noted when calculating Also called “open collector outputs”, sinking outputs are the frequency. With asymmetrical targets, for example, compatible with any logic family because they can be with narrow tooth widths as compared to the distances used for a wide range of supply and ­ utput voltages. o between teeth, the time between the leading and trailing F ­ urthermore, the supply voltage used to power the Hall edge of the tooth is the governing factor. ZF sensors have assembly may differ from the pull-up voltage to which maximum response times from approximately 10 μS it is connected.

If the required response The external pull-up resistor connected between time is very close to these limits, it can lead to unex­ the ­ utput and supply voltage is required for proper o pected results, such as lost counts. Unlike passive speed sensors (VR or variable reluctance With the resistor connected as shown, the output will sensors), a GS sensor has an output amplitude that is be “pulled up” to the supply voltage (Vcc) level when off i ­ndependent of input frequency (speed). This means that and (approximately) to ground when on. the sensor does not require a minimum speed. However, it does require some initial movement of the target in o ­ rder to locate the tooth edge. We therefore prefer to call it a “near-zero-speed” sensor. Recommended pull-up resistor values * Volts DC * Precise values supplied on request.
