6.4 Hysteresis
6.4.1 Definition of the hysteresis
The Hysteresis is the difference between switch-on and switch-off point. It is defined as a percentage of the
sensing distance
𝑆𝑆𝑆𝑆
. Without hysteresis
𝐻𝐻
, objects could at the limit of the switching points lead to ceaseless
on/off switching or bouncing.
6.4.2 Calculating the hysteresis
The absolute hysteresis
𝐻𝐻
can be calculated by taking the Hysteresis
ℎ
value from the data sheet.
𝐻𝐻 = 𝑆𝑆𝑆𝑆 × ℎ
For the sensors should be noted that the upper range
𝑆𝑆𝑆𝑆𝑆𝑆
can be changed by using the FLEX MOUNT
function. If FLEX MOUNT is active, the current value
𝑆𝑆𝑆𝑆𝑆𝑆
can be read in the FLEX MOUNT menu.
𝑆𝑆𝑆𝑆 = 𝑆𝑆𝑆𝑆𝑆𝑆 − 𝑆𝑆𝑆𝑆𝑆𝑆𝑆𝑆𝑆𝑆ℎ 𝑝𝑝𝑝𝑝𝑆𝑆𝑝𝑝𝑆𝑆
