TX
Best seller with broad
lineup and AC 2000 V
breakdown voltage.
FEATURES
1. 2,000 V breakdown voltage between
contact and coil
The body block construction of the coil
that is sealed at formation offers a high
breakdown voltage of 2,000 V between
contact and coil, and 1,000 V between
open contacts.
2. 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. (Bellcore)
3. Nominal operating power: High
sensitivity of 140mW
By using the highly efficient polar
magnetic circuit “seesaw balance
mechanism”, a nominal operating
power of 140 mW (minimum operating
power of 79 mW) has been achieved.
4. High contact capacity: 2 A 30 V DC
5. Compact size
15.0(L) 7.4(W) 8.2(H) .
591(L) .291(W) .323(H)
6. The use of gold-clad twin crossbar
contacts ensures high contact
reliability.
*We also offer a range of products
with AgPd contacts suitable for use
in low level load analog circuits
(max. 10V DC 10 mA).
7. Outstanding vibration and shock
resistance
Functional shock resistance: 750 m/s2
Destructive shock resistance:
1,000 m/s2
Functional vibration resistance:
10 to 55 Hz (at double amplitude of
3.3 mm .130 inch)
Destructive vibration resistance:
10 to 55 Hz (at double amplitude of
5 mm .197 inch)
