Interfacing Variable Reluctance and Proximity Speed Sensors to the NI 660x Counter Devices

Hi.. Sometime in February, 2019 I had accessed the white paper titled "Interfacing Variable Reluctance and Proximity Speed Sensors to the NI 660x Counter Devices" that had the link http://www.ni.com/white-paper/3531/en/

However, when I try to access link today, it doesn't let me do it and the page says the white paper may have been moved or deleted. Does anyone have access to this pdf ? Can anyone send me a copy ?

Thanks.
