All M400 Series electromagnetic locks are symmetrical with field-selectable handing,
allowing optimum placement of the magnet no matter the application. They are
designed to provide automatic voltage sensing for 12 and 24 volts along with polarity
protection to make wiring less complex. M490 models are tested and certified to meet or
