TX-S RELAYS
FEATURES
1. Nominal operating power:
High sensitivity of 50 mW
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 10160 sec. (FCC part 68)
Surge breakdown voltage between
contact and coil:
2,500 V 210 sec. (Telcordia)
5. Low thermal electromotive force
(approx. 0.3 V)
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 V.
6. A range of surface-mount types is
also available.
SA: Low-profile surface-mount
terminal type
SS: Space saving surface-mount
terminal type
7. Sealed construction allows
automatic washing.
8. Sealed according to RTIII (IP67
