Very High Sensitivity,
50 mW (nominal operating)
Rely with LT style
pin layout
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 10160 sec. (FCC part 68)
Surge breakdown voltage between
contact and coil:
2,500 V 210 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.

also available.
SA: Low-profile surface-mount
terminal type
SS: Space saving surface-mount
terminal type
7. Sealed construction allows
automatic washing.
