Passive magnetic speed sensors can provide a signal from the inside of an aircraft engine at temperatures approaching 425° C or from the hub of an automobile wheel at high shock and vibration.

This hall effect magnetic speed sensor can detect each change in target movement, regardless of speed, from near zero to 15 kHz frequency range, generating a steady pulse train of frequency proportional to target speed.
