TESTING
Small size, controlled 7.5A
inrush current possible
Compliance with RoHS Directive
FEATURES
1. Small size, controlled 7.5A inrush
current possible
2. 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.
3. Outstanding surge resistance.
Surge breakdown voltage between
open contacts:
1,500 V 10×160µ sec. (FCC part 68)
Surge breakdown voltage between
contact and coil:
2,500 V 2×10µ sec. (Bellcore)
4. 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.
5. High contact capacity: 2 A 30 V DC
6. Compact size
15.0(L) × 7.4(W) × 8.2(H) .591(L) ×
.291(W) × .323(H)
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)
8. Sealed construction allows
automatic washing.
