RoHS compliant
TX-S RELAYS
FEATURES
TYPICAL APPLICATIONS
1. High sensitivity and Nominal
operating power of 50mW
2. Compact size
15.0 (L) × 7.4 (W) × 8.2 (H) mm
.591 (L) × .291 (W) × .323 (H) inch
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.
1,500 V 10×160 μsec. (FCC part 68)
(open contacts)
2,500 V 2×10 μsec. (Telcordia)
(contact and coil)
5. Low thermal electromotive force
(approx. 0.3 μV)
1. Communications
(XDSL, Transmission)
2. Measurement
3. Security
4. Home appliances, and audio/visual
equipment
5. Medical equipment
