Technical Terms
2-3. Temperature Characteristics of Hysteresis Voltage
The detection voltage (−V
among products of the same specification. The variation of detection voltage between the specified minimum
(−V
The release voltage (+V
among products of the same specification. The variation of release voltages between the specified
minimum (+V
22 ). The range is calculed from the actual detection voltage (−V
−V
The temperature change of the hysteresis voltage is expressed as
as follows:
Example: For the S-80815CN, the detection voltage lies in the range of 1.470≤(−V
Example: For the S-80815CN, the release voltage lies in the range of 1.514≤(+V
