# How can I calculate the hysteresis of Reed sensor?

As question says, I want to calculate the hysteresis of Reed sensor and I don't know how. As I seen in Reed sensor's documentation, hysteresis may be x/y, or the difference between x and y, and I'm not sure which is true.

• I see the picture and understand it but it's not clear what is confusing you. – Andy aka Jun 2 '17 at 9:22
• How can I calculate hysteresis based on this picture?. I have a set of values for Reed sensor. For example if x = -20 and y = 15, how can I calculate hysteresis based on this? I mean, which is the formula for hysteresis calculation? – Linksx Jun 2 '17 at 9:25
• I have no idea what those numbers are or represent. – Andy aka Jun 2 '17 at 9:26
• Those numbers represent distance of magnet from reed sensor, they are coordinates. – Linksx Jun 2 '17 at 9:27
• So, what is it that confuses you? – Andy aka Jun 2 '17 at 9:36

• I understand it. Absolute difference between the distancesis what I was looking for. Thank you for your explanation sir. – Linksx Jun 2 '17 at 9:40
