FEATURES

• Sealed to meet the combination

process of automatic wave soldering

and cleaning needs

• Latching types available

• High switching capacity and high

sensitivity in subminiature size

150 mW pick-up, 8 A inrush capacity:

51 A for 1a1b, 35 A for 2a

• High shock and vibration resistance

Shock: 20 G, Vibration: 10 to 55 Hz at

double amplitude of 2 mm

Contacts

Coil (polarized) (at 25°C 77°F)

#1 This value can change due to the switching frequency, environmental conditions,

and desired reliability level, therefore it is recommended to check this with the

actual load.

Remarks

* Specifications will vary with foreign standards certification ratings.
