High Breakdown
Voltage Relay
RoHS compliant
FEATURES
1. Approved to the supplementary
insulation class in the EN standards
(EN60950).
The insulation distance between the
contact and coil meet the
supplementary insulation class of the
EN60950 standards as required for
equipment connected to the telephone
lines in Europe.
Satisfies the following conditions:
• Clearances: 2.0 mm .079 inch or
more
• Creepage distance: 2.5 mm .098 inch
or more
2. 3,000 V breakdown voltage between
contact and coil.
The body block construction of the coil
that is sealed formation offers a high
breakdown voltage of 3,000 V between
contact and coil.
3. Nominal operating power:
High sensitivity of 200mW
By using the highly efficient polar
magnetic circuit “seesaw balance
mechanism”, a nominal operating
power of 200 mW has been achieved.
4. High contact capacity: 2 A 30 V DC
5. High contact reliability achieved
with gold-clad crossbar twin
contacts and the use of gas
expelling materials during
formation.
*We also offer a range of products with
AgPd contacts suitable for use in low
level load analog circuits (Max. 10V
DC 10 mA).
6. Outstanding vibration and shock
resistance.
Functional shock resistance: 750 m/s2
Destructive shock resistance:
1,000 m/s2
Functional vibration resistance:
10 to 55 Hz (at double amplitude of
3.3 mm .130 inch)
TX-D RELAYS
Destructive vibration resistance:
10 to 55 Hz (at double amplitude of
5 mm .197 inch)
7. Sealed construction allows
automatic washing.

NOTES
1. Packing style
1) Tube packing
The relay is packed in a tube with the
relay orientation mark on the left side, as
shown in the figure below.
Orientation (indicates PIN No.1) stripe
3) Ambient temperature when
transporting and during storage with the
product in its original packaging:
–40 to +70°C –40 to +158°F
2. Automatic insertion
To maintain the internal function of the
relay, the chucking pressure should not
exceed the values below.
A
Stopper (gray)
C
3. M.B.B. type
A small OFF time may be generated by
the contact bounce during contact
switching. Check the actual circuit
carefully.
If the relay is dropped accidentally, check
the appearance and characteristics
including M.B.B. time before use.

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
avoided.
