The release voltage is a voltage at which the output turns to “H”. The release voltage varies slightly among products of
the same specification. The variation of release voltages between the specified minimum (+V

The temperature changes of the hysteresis voltage is expressed as
follows:
Example: For the S-1000C15, the detection voltage lies in the range of 1.485 ≤ (−V
Example: For the S-1000C15, the release voltage lies in the range of 1.530 ≤ (+V
