An elevator door coupler includes a vane member adapted to be supported on one of a hoistway door or an elevator car door. A magnetic coupler device (500) is adapted to be supported on the other of the hoistway door or the elevator car door to be selectively magnetically coupled with the vane member. The magnetic coupler device includes a plurality of modules (520) each having a core and at least one coil associated with the core. An insulation material (528) occupies a space between the modules for substantially insulating adjacent coils from each other and for maintaining a desired alignment of the modules relative to each other.
