Miniature dc power relays cut energy consumption, production costs

For appliance, energy management, motor control, and lighting applications, 15- to 20-A AZ7555 power relays consume one-sixth the energy of conventional 5-mm-pin, general-purpose relays while costing 20 to 30% less than equivalent latching relays. The relays are available in standard, sensitive, and super-sensitive versions, and the super-sensitive version has a typical power consumption at pickup of 67.5 mW. They are priced under $1.00 each in 10,000-piece quantities.

The relays provide fail-on/off without additional circuitry, and are available with SPST (1 Form A) and SPDT (1 Form C) silver-tin-oxide contacts. Suitable for applications from 3 to 110 Vdc, the standard, sensitive, and super-sensitive versions provide maximum continuous power dissipation at 68°F of 1.2, 0.9, and 0.2 W, respectively. Dielectric strength is 5,000 Vrms between coil and contact, plus the relays have 10-kV surge resistance.  Class F insulation and epoxy sealing are optional.
