Another way of identifying a fake cable is to examine the rectangular piece of the cable where the Hall chip is positioned; a properly working cable will have a total of 4 printed circuit traces visible (3 from the Hall chip and 1 from the tiny capacitor) but only 3 (2 from the Hall chip and 1 from the capacitor) on the fake.
Beware of fake versions of this cable 821-1151-A from many suppliers. The Hall Effect magnetic switch will then not work because the printed circuit traces on the cable are incorrect. The fake cable can be identified by an ohmmeter showing the two contacts for the Hall chip farthest from the cable edge to be shorted together.
