1
Relative Timing Accuracy Range is the change in edge position over the operational air gap and temperature range that
can be expected from a single device. This does not include part-to-part variation.
2
The Typical Absolute Timing Accuracy is the difference between the target mechanical edge (rising or falling) and the
corresponding sensor electrical edge.
3
Phase Delay is the change in edge position over the operational RPM range that can be expected from a single device.
This does not include part-to-part variation or variation due to temperature.
4
The TPOS Air Gap Min is the Installation Air Gap where the device may detect Valleys as Teeth. The True Power On
Function is
NOT
guaranteed to operate.
5
The TPOS Air Gap Range is the Installation Air Gap Range where the True Power On Function is guaranteed to
operate. Operating is defined as correctly detecting a tooth when powered up over a tooth and correctly detecting a valley
when powered up over a valley using the Reference Target. This specification is only valid for targets that meet or
exceed the ‘Gear Parameters for Correct TPOS Operation’ section of this document.
6
The TPOS Air Gap Max is the Installation Air Gap where the device may detect a Tooth as a Valley. The True Power On
Function is
NOT
guaranteed to operate.
