*Magnets also available, Available Cut and Bent as Well as on Reed.

Notes:
1.Pull-in & drop-out were measured by using OKI standard coil.*This value of drop-out is prescribed when pull-in is over 20AT. When pull-in is less than 20AT, drop-out are 5 MIN & RLS/OP >0.7, Tolerance at measurement is ±2AT. (Fig.1)

2.Measurements are made by the four-terminal voltage reduction method where the 100AT excitation is given to the switch using the OKI standard coil to close the contacts, and 10mA current is applied.

3.This value varies depending on the pull-in value (contact gap). In this measurement, the pull-in value is about 20AT.(MIL-STD-202D METHOD 301)

4.Measurement is made by using a DC 100V super megger.(MIL-STD-202D METHOD 302)

5.The value shows the time required for the contacts to cause the first contact bounce after applying the voltage to the OKI standard test coil. The times is shown at top in Fig.2

6.Bouncing is caused when the contact close. Bounce time means the time when opening and closing of the contacts are being repeated before the contacts are completely closed. Shown by T bounce.

7.Release time means the time from the morment the voltage applied to the test coil as removed to the moment the contacts open. Shown by Tris.

8.Resonant frequency is a vibrating frequency inherent to the reed switch. Avoid application of vibration at this frequency to the switch, otherwise it will cause misoperation.

9.The reed switch can be operated with a frequency higher than the maximum operating frequency. However, operation with such a frequency will often cause an endless chattering at the time of ON operation. It is recommended for the designer to take the maximum operationg frequency into consideration when designing systems and circuits.

10.Dimensions of standard coil.
A:Inner diameter of standard coil.
B:Length of standard coil.

11.If a shock of more than 30G is applied to a reed switch, the pull-in value of the switch will be often caused to change from the standard specification. Therefore, it is recommended not to use the reed switch which has been given such a shock.

12.If a vibration of more than 1 kHz is applied to a reed switch, even a very small acceleration to it will easily cause the switch to misoperate to close due to its resonant frequency.

13.In practice the reed switch can operate beyond the specified range. In case of magnet driving. however, some magnets show decrease of magnetic flux even at the lowest temperature of the range depending on their temperature characteristics. There fore, it is recommended to consider the range as a general guide line.

14.The actual tensile strength is more than 5 kg (breakdown). However, considering the lead not to get out of position, the value for the static load is shown here.
