Electromechanical Relays
Hasco Component's electromechanical relays range from less than an amp to 80 amps. Hasco's
relays are UL and CSA with some TUV ratings. All relays have DC coils and many have an AC coil.
They come sealed for wave soldering and washing thereby allowing the relays to be put on any
assemble line. There are surface mount low current relays available as well.
