NOTES

1. Coil operating power

1) As a general rule, only a pure DC pow-

er supply should be used for the coil drive.

2) To ensure proper operation, the voltage

applied to both terminals of the coil should

be

voltage of the coil. Also, be aware that the

pick-up and drop-out voltages will fluctu-

ate depending on the ambient tempera-

ture and operating conditions.

3) The ripple factor for the voltage applied

to the coil should be less than 5%.

4) For set and reset latching relays, the

rated operating voltage should be applied

to the coil for 10 ms or more.

2. Coil connection

When connecting coils, refer to the wiring

diagram to prevent mis-operation or mal-

function.

3. External magnetic field

Since SX relays are highly sensitive polar-

ized relays, their characteristics will be af-

fected by a strong external magnetic field.

Avoid using the relay under that condition.

4. Cleaning

In automatic cleaning, cleaning with the

boiling method is recommended. Avoid ul-

trasonic cleaning which subject the relay

to high frequency vibrations. It may cause

the contacts to stick.

lt is recommended that a fluorinated hy-

drocarbon or other alcoholic solvent be

used.

5. Packing style

1) The relay is packed in a tube with the

relay orientation mark on the left side, as

shown in the figure below.

2) Tape and reel packing

(1) Tape dimensions

(2) Dimensions of plastic reel

6. Automatic insertion

To maintain the internal function of the re-

lay, the chucking pressure should not ex-

ceed the values below.

Chucking pressure in the direction A:

4.9 N {500 gf} or less

Chucking pressure in the direction B:

9.8 N {1 kgf} or less

Chucking pressure in the direction C:

9.8 N {1 kgf} or less

Please chuck the

portion.

Avoid chucking the center of the relay.

In addition, excessive chucking pressure

to the pinpoint of the relay should be also

avoided.
