1. A latch module for an electronic access system that provides controlled access to a secure area, the latch module being configured for mounting to a panel defining a pre-sized aperture without modifying the size of the pre-sized aperture, the latch module comprising:
a housing at least partially defining an interior space;
a cable extending from the interior space of the housing and being connected to the latch module to deliver either power or signals either to or from the latch module;
a rotatable member that is rotatably coupled to the housing;
a pawl mounted to the rotatable member, the pawl being rotatable between a locked position to prevent access to the secure area and an unlocked position to permit access to the secure area;
a sleeve that is fixed to the housing and at least partially surrounds the rotatable member, such that the rotatable member rotates with respect to the sleeve, the sleeve defining a recess positioned to accommodate the cable and through which the cable passes;
a fastener that is configured to be mounted to the sleeve for attaching the latch module to the panel; and
a washer that is configured to be positioned between the fastener and the panel, the washer defining a channel positioned to accommodate the cable and through which the cable passes so as to either limit or prevent the fastener from compressing the cable;
wherein the recess defined by the sleeve and the channel defined by the washer together form a cable passage when the recess and the channel are aligned; and
wherein the pre-sized aperture defined by the cable is configured to receive the sleeve and the cable without modifying the size of the pre-sized aperture.
