Cautions
*The open of CD terminal may cause double pulses shown in Figure 8 at release. If the double pulses cause a
trouble, attach 10pF or larger capacitor to the CD terminal. Do not apply the voltage to the CD terminal.
Time
Figure 8
*Layout the print circuit board not to apply or flow out the current to/from the CD terminal. Doing not so may cause
inaccurate delay time.
*Use an external capacitor, CD of which leakage current can be ignored for the built-in constant-current value. A
leakage current may cause an error of delay time. Also, a leakage current over the built-in constant-current
causes unrelease status.
3. Other characteristics
(1) Temperature characteristic of detection voltage.
The temperature characteristics of the detection voltage are expressed by the oblique line parts in Figure 9.

(2) Temperature characteristics of release voltage
The temperature factor (
) of the release voltage is calculated by the temperature factor of the
detection voltage as follows:

The temperature factor of the release voltage has a same sign characteristics as the temperature factor of the
detection voltage.
(3) Temperature characteristics of hysteresis voltage
The temperature characteristics of hysteresis voltage (
