Switch Points

Switch points (±S) is a pair of pre-defined angles which set off the operation zone and critical zone
(→4.5 Output explained). The S can be set with a unit of 0.1° and in default only symmetrical switch
points are allowed, ie. Switch points is always ±3 or ±45°.
Example: Switch point = ±3°
Sensor position at (-3°,+3°), the output will be in the operation zone.
Sensor position at (-3°, -90°) and (+3°, +90°), the output will be in the critical zone.
An asymmetrical switch points such as (+2°, +80°) can also be requested with a customized
configuration. Contact your local distributor for more information.
4.7.2

Hysteresis

By creating a hysteresis, we can prevent sensor constantly switching at the switch point. The actual
switch point from critical to operation zone will be ±S', whose value is the programmed switch point
S minus Hysteresis.
