An overhead door position sensor assembly includes a sensor actuating device, and a position sensor including a roller track clamping device for mounting the position sensor onto a roller track of an overhead door assembly. The sensor actuating device is mountable to an overhead door of the overhead door assembly for actuating the position sensor when the sensor actuating device is located within a minimum actuation distance from the position sensor. The roller track clamping device includes a body having a main member for placement adjacent to a sidewall of the roller track and a curved resilient member extending from the main member for placement along the contour of a curved roller race that extends from the sidewall of the roller track. A bracket of the roller track clamping device is coupled to the body. A plurality of serrations located on one of the body and bracket engage with an edge of a slot located on the other of the body and the bracket to allow the body and the bracket to be coupled in a ratchet-like manner. The resilient member of the body includes a flexible thin section that conforms to the roller race and prevents the roller track clamping device from slipping along the roller track. When installed, no part of the position sensor assembly interferes with travel of the overhead door along the roller track.

Compressible door track magnet module

A resilient and compressible door channel magnet module facilitates the installation of a door channel magnet. The module comprises a magnet set supported inside a magnet holder that is connected to a flexible and deformable outer ring by a set of elongate web members. To install, the module is compressed, positioned in the door channel, and released. The pressure of the module against the walls of the door channel retains the module in position. A preferred module includes a rare earth magnet backed with a ceramic magnet for producing the requisite magnetic field strength at less cost than a sole rare earth magnet of equal magnetic field strength.
