TX RELAYS
FEATURES
TYPICAL APPLICATIONS
1. 2,000 V breakdown voltage between
contact and coil
2. Outstanding surge resistance.
1,500 V 10×160μ sec. (FCC part 68)
(open contacts)
2,500 V 2×10μ sec. (Telcordia)
(contact and coil)
3. Nominal operating power: High
sensitivity of 140mW
4. High contact capacity: 2 A 30 V DC
5. Compact size
15.0 (L) × 7.4 (W) × 8.2 (H) mm
.591 (L) × .291 (W) × .323 (H) inch
6. 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).
1. Communications (xDSL,
Transmission)
2. Measurement
3. Security
4. Home appliances, and audio/visual
equipment
5. Medical equipment
