FEATURES
1. 2 Form C Slim type
14.0(L) ×9.0(W) ×5.0(H) .551(L) ×
.354(W) ×.197(H)
Small header area makes higher
density mounting possible
2. Nominal operating power:
High sensitivity of 140mW (Single
side stable type)
By using the highly efficient polar
magnetic circuit “seesaw balance
mechanism”, a nominal operating
power of 140 mW (minimum operating
power of 79 mW) has been achieved.
3. Surge breakdown voltage:
1500 V FCC Part 68
4. Outstanding vibration and shock
resistance.
Functional shock resistance: 490 m/s2
Destructive shock resistance: 980 m/s2
Functional vibration resistance:
10 to 55 Hz (at double amplitude of
3 mm .118 inch)
Destructive vibration resistance:
10 to 55 Hz (at double amplitude of
5 mm .197 inch)
5. High density mounting possible
High-efficiency magnetic circuits
ensure low magnetic flux leakage.
Because characteristics are little
changed by proximity mounting, high-
density mounting is possible.
6. The use of gold-clad twin crossbar
contacts ensures high contact
reliability.
*We also offer a range of products
with AgPd contacts suitable for use
in low level load analog circuits
(Max. 10V DC 10 mA).
*SX relays designed for low level
loads are also available.
7. Low thermal electromotive force
As well as low power consumption of
140 mW, use of a structure with
separate coil and contact sections has
reduced thermal electromotive force to
the low level of approximately 5 µV.
8. Latching types also available
9. Self-clinching terminal also
available
10. Sealed construction allows
automatic washing.

1. Coil operating power
Pure DC current should be applied to the
coil. The wave form should be
rectangular. If it includes ripple, the ripple
factor should be less than 5%.
However, check it with the actual circuit
since the characteristics may be slightly
different. The nominal operating voltage
should be applied to the coil for more
than 10 ms to set/reset the latching type
relay.
2. Coil connection
When connecting coils, refer to the wiring
diagram to prevent mis-operation or
malfunction.
3. External magnetic field
Since T series relays are highly sensitive
polarized relays, their characteristics will
be affected by a strong external magnetic
field. Avoid using the relay under that
condition.
4. Packing style
The relay is packed in a tube with the
relay orientation mark on the left side, as
shown in the figure below.
5. Automatic insertion
To maintain the internal function of the
relay, the chucking pressure should not
exceed the values below.
Chucking pressure in the direction A:
9.8 N {1 kgf} or less
Chucking pressure in the direction B:
9.8 N {1 kgf} or less
Chucking pressure in the direction C:
4.9 N {500gf} 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
avoided.
6. Soldering
Preheat according to the following
conditions.
Soldering should be done at 260±5°C
500±41°Fwithin 6 sec.
