Abstract
An electromagnetic lock employs a pre-wound bobbin which is forced onto the E-shaped lamination stack of a magnetic core. The housing is configured in two longitudinal sections which are relatively pivotal to provide access for circuitry within the housing for both an outswinging and an inswinging door lock installation. The electromagnet also employs a circuit to sense the power supply to the electromagnet and to automatically select the operating voltage of the electrical coil.
