ORDERING INFORMATION
Very High Sensitivity,
50 mW (nominal operating)
Relay with LT style
pin layout
TX-S RELAYS
RoHS compliant
FEATURES
1. Nominal operating power:
High sensitivity of 50mW
By using the highly efficient polar
magnetic circuit “seesaw balance
mechanism”, a nominal operating
power of 50 mW (minimum operating
power of 32 mW) has been achieved.
2. Compact size
15.0(L) × 7.4(W) × 8.2(H) .591(L) ×
.291(W) × .323(H)
3. High contact reliability
High contact reliability is achieved by
the use of gold-clad twin crossbar
contacts, low-gas formation materials,
mold sealing the coil section, and by
controlling organic gas in the coil.
*We also offer a range of products
with AgPd contacts suitable for use
in low level load analog circuits
(Max. 10V DC 10 mA).
4. Outstanding surge resistance.
Surge breakdown voltage between
open contacts:
1,500 V 10×160 µsec. (FCC part 68)
Surge breakdown voltage between
contact and coil:
2,500 V 2×10 µsec. (Telcordia)
5. Low thermal electromotive force
(approx. 0.3 µV)
The structure of the mold-sealed body
block of the coil section achieves
nominal operating power of 50 mW
and high sensitivity, along with low
thermal electromotive force, reduced
to approximately 0.3 µV.
6. Sealed construction allows
automatic washing.

2. Specifications
Notes: *1 This value can change due to the switching frequency, environmental conditions, and desired reliability level, therefore it is recommended to check this with the
actual load. (AgPd contact type is available for low level load switching [10V DC, 10mA max. level])
*2 Refer to 6. Conditions for operation, transport and storage mentioned in AMBIENT ENVIRONMENT (Page 24).

To maintain the internal function of the
relay, the chucking pressure should not
exceed the values below.
Chucking pressure in the direction A:
4.9 N {500gf} 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
avoided.
